Husqvarna adds dust extractor to its Pace battery system

Husqvarna Construction has now added the dust extractor DE 120 H Pace to its 94V Pace battery system. This ‘H’ class development has a compact and mobile design, developed for long working intervals. The Pace battery system supports a range of heavy duty machines that provides the operator with 94v of power which can be applied to jobs at sites where previously only combustion powered alternatives have been an option. According to Husqvarna, the development can provide operators with the mobility of cordless equipment and covers a range of applications. These include working in remote places with no access to the electrical grid, urban areas where noise level or emissions are an issue, or in tunnels and trenches where emissions can cause problems for the operator. “As a trusted partner to our customers, we want to support them in getting the most demanding jobs done, even in remote, off grid locations,” says Joe Taylor, vice president product and service management at Husqvarna Construction. “With the Pace battery system, we have a powerful range of machines as a strong alternative for operators who prefer all the benefits that a battery product can offer but need high power for heavy duty applications.”

New ‘Ronda’ 4000H ‘QC’ class ‘H’ vacuum cleaner with four motors

A new member has been added to the Ronda range of industrial vacuum cleaners, the Ronda 4000H QC (short for ‘Quad Core’). This new vacuum cleaner is constructed with the same frame and filter system as the Ronda 2800H, but with a new motor top. It is suited for collecting large volumes of fine and hazardous dust, or act as a dust extractor on, for example, floor grinders or other cutting or grinding machines that usually produce large volumes of fine dust. As standard it is equipped with Longopac bagging system but can also be delivered with other collection systems such as a metal container or a combination of Longopac and container. A built in acoustic alarm sounds if the air velocity in the hose falls below 20m/s ensuring that the 4000H QC meets the European standard requirements for vacuum cleaners used as dust extractors attached to tools such as floor grinders. According to Ronda’s manufacturer V. Brøndum, the measurement of the air flow (which forms the basis for the acoustic alarm) is offered by most vacuum cleaner manufacturers of H class single motor vacuum cleaners, but only a few manufacturers offer it on multi motor vacuum cleaners, as in the case of the Ronda 4000H QC. The machine is fitted with four suction motors, each of max 900W, and the machine does not exceed the max 3,600W required to operate at 230V (it can also be supplied as 380V). The model is equipped with soft start which protects the motors as well as the building installations. The motors can be started individually, for example in situations where 16A is not available or for less demanding tasks that require only two or three motors.

New dust extractor models from Scanmaskin

Scanmaskin has introduced three dust extractors, namely the 3000, 4000 and 7000 World Series. The 3000 World Series dust extractor is designed for use with Scanmaskin’s single phase floor grinding machines. It has a height of 130cm, a robust frame and large wheels, and comes with a 10m hose and 10m power cable which gives a full 20m range. It is supplied with a cleaning kit containing a 50mm aluminium pipe and a cleaning nozzle of 450mm and suits the grinders ‘Scan Combiflex’ 330 and 450 as well as the Scanmaskin 18. The suctioned air is conveyed and discharged outside at low speed.

The 4000 World Series is specially designed for use with Scanmaskin’s mid-range line of grinding and polishing machines. It is equipped with a ‘PCB’ electronic circuit, which enables automatic start/stop functionality for the motors. It features a sturdy frame and large wheels and is supplied with 10m of hose and a cleaning kit containing a 50mm diameter aluminium pipe, including a cleaning nozzle of 450mm. It also offers the option of connecting a pre-separator and suits the floor grinders Scan Combiflex 330 three phase, Scan Combiflex 450 and Scan Combiflex 500. Both the 3000 and 4000 features an ‘M’ class polyester star filter. The filter is abrasion resistant, and the filter pockets are sealed with glued seams. Both of these models have a clogging monitoring system of filters with an indication of the filter’s status.

The 7000 World Series is intended to be used together with Scanmaskin’s larger floor grinders. This vacuum cleaner features a double stage side channel blower as well as a motor and filter system designed for continuous use. Other features include ‘M’ rated and oversized cartridge filters (‘PTFE’ treated and with nanofibers). It also has a fully automatic and continuous filter cleaning system using reverse pressure from compressed air from the Thomas compressor. As the compressor is oil less, it is said that no maintenance is required. The max pressure is regulated by an overpressure valve. It features a robust construction and large wheels and is built for industrial use. Scanmaskin offers additional accessory kits for general cleaning and a 76mm hose with camlock for connection to the grinding machine. It suits the larger floor grinders such as Scan Combiflex 650 and Scanmaskin 28 World Series. 

The 3000, 4000 and 7000 World Series models are all H classed, and are equipped with Longopac as well as Hepa 14 filters, which removes 99.995% of particles as small as 0.18μm. The filters have been ‘DOP’ tested, and the models features a bag in, bag out system developed for the safe replacement of the primary filter and preventing operators from being exposed to dust during maintenance.
