Taking a look at what’s new in dust control and disinfectionPublished 29/6 at 13:35
This year sees the introduction of many new products from dust control manufacturers; although this time some of these new developments aren’t actually combatting dust. During the ongoing pandemic, the sector has found innovative ways to offer other solutions that can help save lives.
The new reality we are currently experiencing reminds of a Hollywood horror or sci fi movie come true. Covid-19 has become the proverbial ‘black swan’ that effectively shut down the global economy, closed the borders and sent entire nations into lockdown. Despite unprecedented measures undertaken by world governments to curb the spread of coronavirus, the death toll keeps climbing albeit now at a decreasing rate. There have however been some interest developments, notably from Italy which suffered initially very badly from the virus, to help combat its spread.
WLP and the NCA remediation system
WLP s.r.l., a dust control specialist based in Northern Italy, is doing its bit to combat the pandemic by offering a decontamination system that can considerably reduce the diffusion of the virus. With severe lockdown measures in place, only businesses that have been classified as ‘essential’ are allowed to continue operating in Italy (at the time this article was written). WLP, a trendsetter in dust and odour control technology, has been granted such a status, not least thanks to its NCA remediation system, which stands for ‘No Contaminated Area’.
WLP began to design and build decontamination systems some four years ago, following a 6.2 Richter scale earthquake in central Italy on 24 August 2016. A great deal of livestock was killed by collapsing stables, causing a real threat of an epidemic. The situation was quickly resolved at the time, but it did prompt the WLP engineering team to look into decontamination issues. Two years later the Italian manufacturer came up with the NCA solution. Designed to hinder the proliferation of dangerous bacteria with the aid of non-toxic additives, a self-contained NCA system consists of an electric generator set, a large volume tank with decontamination solution and a spraying cannon or nebulizer. Thanks to the on board electronics and a radio controlled unit, the system can be operated in remote mode, which drastically reduces the risk of the operator being infected. Complete autonomy and the ability to treat large areas are further benefits of the WLP solution.
Due to the current coronavirus situation, WLP has not only remained fully operational throughout the crisis, but in fact, has increased production of decontamination systems. This has enabled the company to respond to the need for sanitising indoor environments such as offices, warehouses and manufacturing facilities by designing a brand new machine. Named ‘ET’ (‘Extreme Treatment’ and ‘Extra Terrestrial’ thanks to its somewhat outlandish design), this mobile system features a 70l tank with sanitising liquid, permitting an average run time of three hours. Also, the ET is equipped with a remote control unit, which allows users to operate it from a safe distance. As the coronavirus crisis worsens, demand for this machine is said to be growing exponentially worldwide. Within a space of just two weeks, WLP has supplied over 60 units to France, the UK, Malta, Egypt and Thailand.
‘DisinfecTunnel’ – the full body sanitizer from EmiControls
Another Italian manufacturer, EmiControls, based in Bolzano, has manufactured a new disinfection tunnel, reminiscent of the common airport body scanner. The user enters the tunnel and stops with outstretched arms. The disinfectant is sprayed through nozzles, forming a fine mist of water which is deposited on all surfaces in the tunnel including skin, clothing, bags or even smartphones. The disinfection process is completed in 15 seconds while the effect lasts up to 24h. The ‘Ersa’ disinfectant used is harmless for humans, which means no protective equipment is necessary when using it. The tunnel uses a high pressure system (70bar) and has been designed in such a way that only a small amount of water and disinfectant is required (0.55l/min). The water is atomized into small droplets of between 1 and 30 microns. The tunnel is operated with drinking water and domestic electricity, and has a quick assembly time of 15min. The DisinfecTunnel can also be used to disinfect objects, being particularly suitable for use in public places, in front of hospitals, at work, in front of entrances and at events, to name but a few.
Disinfecting equipment from Savic Engineering
The government of Spain asked Belgium based Savic Engineering to use its industrial dust suppression and disinfecting equipment to help combat Covid-19. A few days were spent testing the machines on site, approving their use before being put to work. The equipment was deployed on a large scale and to great eﬀect to thoroughly disinfect spaces destined for the care of Spanish coronavirus patients, with public areas receiving a similar treatment. Savic Engineering’s Spanish dealer cooperated closely with the local authorities and the army. “Our ‘Spraystream’ machines can generate droplets of water mixed with disinfectant in a highly controlled fashion,” says CEO Mirko Savic. “We then use a turbine system to spray this mixture onto surfaces and through the air. The machines are controlled remotely and are suitable for fully autonomous, vehicle mounted operation. This makes it possible to disinfect large areas quickly at the correct ﬂow rate and dosage. Moreover, our system is set up in such a way that we can work very eﬃciently, without ﬂooding the surroundings with water and with a minimum of workers. We have a large supply of equipment available that is perfectly suited to these tasks with only a few modiﬁcations, either indoors or out.”
New low weight pre separator from Blastrac
For more conventional dust control equipment for use in demolition, Blastrac has launched a new pre separator, namely the BPS-LP-0020, which possesses both flexibility and low weight. It captures up to 95% of dust, measured with a 2m dust hose between the pre separator and the dust collector and is designed to work in combination with small Blastrac dust collectors. It is made from recyclable and lightweight plastic materials, weighing only 6.5kg. The separator is multifunctional due to its trolley system, which can be used stand alone or with a hook on system making it attachable to the BDC-122 and the BDC-133. The pre separator is equipped with a Longopac bagging system, as well as a tube on the frame for tie wraps and scissors. The manually operated valve ensures that the full Longopac bag can be changed while the dust collector remains turned on, thereby reducing downtime. The turntable mounted on the trolley provides ergonomic advantage to easily turn the full Longopac bag and close it.
Blastrac has also launched a petrol powered dust collector, BDC-187PLP-UD, also equipped with a Longopac bagging system for 25kg bags. It is equipped with the ‘Up & Down system’ (‘low’ position for transportation and ‘high’ when in operation) which, according to Blastrac, makes it easy to transport from jobsite to jobsite. This dust collector can be used in combination with the BMP-335GHY scarifying machine and BMC-335GHY sawing machine. This means the operator does not need to bring a generator to the jobsite.
Schwamborn offers redesigned suction system for demanding jobs
Schwamborn believes that there are two challenges when milling and grinding floors, walls and ceilings: on the one hand, it is dangerous because of the amount of dust it produces, which therefore implies that fewer workers are willing to perform such jobs. On the other hand, there are numerous excuses in the industry to proceed without perfected dust reduction. With this dilemma as a starting point, Schwamborn has aimed at breaking new grounds. “As a result we can now present a completely redesigned suction system that is perfectly adapted to the requirements on the construction sites,” says CEO Eckart Schwamborn. Schwamborn now offers a suitable suction system for particularly demanding requirements related to grinding and milling contaminated or environmentally harmful material. STS 130 and STS 260 are examples of H-certified models that meet such standards.
Last year, Schwamborn reworked its entire dust extraction line and improved the suction capacity for almost all models in the new STS line. As a consequence, the three stage filtering was improved, with the installing of HEPA 13 and HEPA 14 standard particle filters. Coarse particles are filtered first and then a polyester pre filter removes up to 99.9% of the dust. In the third stage, up to 99.995% of all dust particles on site are filtered by HEPA filters. “Our goal had to be the development of a system that was maximally closed, realistic and easy to implement on site,” says Eckart Schwamborn. “Our new suction system guarantees easy handling on site and increases the likelihood that it will actually be used.” The new suction machine has an easy to use click system, antistatic hoses and a quick coupling system for hose extensions. It is rounded off by large, built in, abrasion resistant wheels, an integrated brake, a holder for cable ties and a Longobag tear resistant dust collector, all fitted as standard.
BlastPro aims to conquer the world
Oklahoma based Blastpro Manufacturing, Inc. is a US manufacturer of surface prep equipment and dust collectors. BlastPro have been operating and manufacturing ‘world class’ surface preparation and dust extraction products with its dust collection systems comprising of a series of four different models: BP-5-54, BP-9-54, BP-9-54-Steel and BP-6-54, with Blastpro’s Chris Glenn stating that the BP-9-54 is its most popular model. This is a three-phase machine running on multiple voltages. It provides a very high efficiency and versatility when working on concrete surfaces, weighing in at about 129kg.
The BP-9-54 is recommended for use with the BP-10 Super-2 and BP-15 Super shot blasters. It houses nine filter cartridges and utilises reverse pulse, filter cleaning technology, cleaning three filters every 13 seconds. The internal EPA filter ensures clean, safe air discharge whilst the large dust bin allows the user to work longer than with comparable dust collectors. It also features two vacuum inlets, allowing additional equipment, such as grinders or edgers, to be operated simultaneously. Other features include a manufactured control panel, circuit breaker, an earth leakage module and a rugged, wear resistant electrical cord. The machine has an internal HEPA filter which is compliant with OSHA 29 CFR 1926.1153 and has a 2,039m3/h capacity and includes an internal EPA filter to ensure clean air discharge.
Expanded dust shroud range from Au Tour du Betón
Au Tour du Beton’s range of steel shrouds dedicated to bush hammering has expanded in recent months, to now comprise of four models in various diameters. A removable cover allows the bush hammer to be used as close as possible to the walls, with the shrouds also being used for grinding with a raised kit. The French company also offers rubber or steel shrouds for grinding and supplies a complete range of machines and consumables for floor preparation, bush hammering, grinding or polishing concrete floors. This includes grinding machines in the ‘Scoot family’, its 220V and 380V grinding machines, bush hammering plates for planetary grinding machines or hand grinders, as well as tailor made accessories and machines dedicated to the concrete industry.
New Longopac version of Dustcontrol’s DC 2900
DC 2900, Dustcontrol’s most popular dust extractor, is suitable for vacuum cleaning and source extraction from handheld power tools (with up to 13cm suction casings) and small table saws. The DC 2900 has a steel chassis with large wheels and is lightweight and portable. The new, Longopac equipped version of the model, DC 2900L, is delivered with one roll of Longopac mini 12 especially developed for the DC 2900L. When ordering Longopac, it is possible to order either Longopac mini 12m (six rolls, 12m each) or Longopac mini 23m (four rolls, 23m each). The DC 2900 is delivered with additional equipment, such as a suction hose, aluminium floor tool, chrome steel suction pipe, fine filter (cellulose) and HEPA 13 filter.
Ronda ‘1800H Power’ vacuum cleaner
Since its introduction almost two years ago, the Ronda 1800H Power has become a very popular machine, not least in the longopac version. The powerful motor makes it possible to use longer suction hoses and the large multi tube filter is suitable for larger quantities of fine material such as concrete and plaster dust. Furthermore, the machine is approved as a class-H vacuum cleaner and is therefore also suitable for hazardous dust. Finally, the machine is very robust and handy thanks to its strong metal frame with integrated tube parking.
No more threads and shavings getting stuck
As to the Ronda 1800H Power with longopac, the longopac bag is, in the standard version, held down by means of a metal grille integrated into the longopac dispenser itself. If the 1800H Power is used for collecting rather long shavings, carpet threads or the like, there may be a risk of these getting stuck in this metal grille causing blockages. For this type of job, V. Brøndum A/S, the manufacturer of Ronda vacuum cleaners, has introduced a smart flap valve to replace the metal grille. The new flap valve has two flaps to maximise the opening and furthermore, it is possible for the user of the machine to adjust counter weights in such circumstances as very light dust. The new flap valve may also be mounted on existing machines.
Two new Klindex vacuum cleaners for large dust quantities
Klindex has introduced the Supervax X3 industrial vacuum cleaner with cyclonic pre separator and ASC automatic filter cleaning system being a compact vacuum cleaner for large quantities of dust. Over 95% of the dust is collected in the pre separator and, consequently, the filters do not clog easily meaning that the machine can work for a long time without filter cleaning. The cyclone pre separator has been integrated inside the machine to avoid the issue of having to move a vacuum cleaner and a pre separator around separately. It has a reduced height for easy transport even in small vans, and is equipped with a HEPA filter, shockproof drum and three independent 1,400W motors.
Klindex has launched a second industrial vacuum cleaner which shares many similarities with Supervak X3. Supervak K23 is also designed to vacuum large quantities of dust, for example dust produced by floor preparation or concrete polishing, has three motors of 220V at 1.400W each; polyester star filter; mechanical filter shaker; pre separator with cyclone; a plastic bag to collect dust, HEPA filter and large wheels. Thanks to the pre separator with cyclone system, over 90% of the dust is collected in the plastic bag positioned inside the pre separator drum. When the plastic bag is full, the operator closes it without contact with the dust.
Scanmaskin presents its most efficient industrial vacuum cleaner
Scanmaskin’s new dust extractors, ‘ScanDust 9000 World Series’ in electric and propane versions, are focused on efficiency, design, ergonomics and ease of service. ScanDust 9000 World Series is the largest and most efficient industrial vacuum cleaner produced by the company due to its filter capacity and built in pre separators which are unique and patented, separating dust into two stages and providing up to 90% pre separation. This means that there is no need to clean the filters as often, which, according to Scanmaskin, gives longer and more disruption free operating time when compared to traditional industrial vacuum cleaners. As the pre separator is built into the machine, the operator does not need to handle or transport extra equipment. “We have listened to our customers, their challenges and wishes, and created an industrial vacuum cleaner that provides a significantly longer operating time and a safer working environment,” says Anna-Lena Lööf, marketing director, Scanmaskin.
The filter area of the ScanDust 9000 World Series is 4.2m² and consists of 32 Teflon coated sock filters and two HEPA 14 filters. HEPA 14 provides a high filtration rate of 99.995% and takes care of the smallest and most dangerous particles despite the high air flow. The electric version of the ScanDust 9000 World Series is equipped with a frequency control which allows adjusting power and speed depending on the application area. The combination of this together with high filter capacity and airflow enables the connection of more machines to the same vacuum cleaner. It has a height adjustable cyclone for better transportation and is equipped with solid rear wheels and 200mm large swivel wheels. The design aim was to make service easy so that the operator can access all parts with no need to disassemble machine parts for access. The vacuum cleaner is equipped with a filter guard that warns when the filters require cleaning, as well as a ‘Jet-Pulse’ cleaning system that easily pulses the filters to keep them clean. This machine is equipped with a Longopac bag system and features a steel construction as well as 95% recyclability.
New pump model for Dynaset high pressure system
Last year Dynaset updated its pump line up for the ‘HPW-Dust’ high pressure dust suppression system by adding the HPW 250 pump model, thereby adding more flexibility to the range, making it able to handle pressure, as well as chemicals such as dust binding agents, more efficiently than previous models. The compact and eco-friendly HPW-Dust system is easy to install onto any mobile machine being suitable for demolition machinery, excavators, screeners and crushers. It uses the hydraulic power of the machine to convert water to high pressure water mist. According to Dynaset, the system provides better dust suppression performance with a smaller water droplet size than traditional low pressure dust suppression systems. The company believes that a smaller droplet size also binds more dust particles with minimal amounts of water. The system is integrated onto the base machine’s attachment head, or where the dust suppression is needed for maximum effect. It has a large variety of nozzles and pumps for configurations to fit all vehicles and dust suppression applications. It comes with a power washing pistol for power washing applications and can also be equipped with a ‘Double Dust’ boosting system that multiplies the dust suppression power.
Three stage dust collection with Superabrasive’s new Lavina Elite series
Superabrasive new ‘Elite’ series of ‘Lavina’ dust extractors includes electric and propane models for use with different size grinders. The line also includes a new pre separator which works between the grinder and the dust collector to capture 95% of the dust before it reaches the dust collector. According to Superabrasive, it extends the life of the vacuum filter and reduces the need to clean it. The new Lavina Elite dust extractors feature three stage dust collection, cyclone, main filter and HEPA, with important upgrades, such as new filters and seals. The main filters consist of a thermally bonded PTFE membrane with ALU coating, and are antistatic and hydrophobic. The new body design provides a smaller and lighter construction for convenient transportation, with easier access to HEPA filters, as well as a filter chamber with more space for dust. On electric models (115V and 220V), motors have separate valves and work independently from each other, so that the vacuum continues to work even if one motor is down.
More ionization with Renluftsteknik’s updated OxySan 2000
During the latter part of 2019, Renluftsteknik in Mölndal, Sweden, updated its air ionizers, providing longer throwing distances and more ionization, which, according to Renluftsteknik, gives a better effect on particles which can sink to the floor faster. Normal ion levels in indoors air is roughly 50-500 ions per cm3 air, but with the new OxySan 2000, the ion level is at 3M ions per cm3 air. Renluftsteknik’s goal with the update, aside from an improved effect on particles, has also been to make service of the air ionizers cheaper and easier.
