Brøndum introduces new remote control
The Denmark based manufacturer of industrial vacuum cleaners Brøndum used bauma to introduce a new smart remote control for its ‘Ronda’ 200H Power and Ronda 1800H Power models. The control is mounted on the hose near the user and makes it possible to start and stop the vacuum cleaner easily and quickly. This new solution is particularly handy for concrete cutting, drilling or grinding tasks. Using machines like concrete grinders necessitates hearing protection, which makes it difficult to hear the vacuum cleaner's acoustic alarm for low airflow. The new Ronda remote control is equipped with a visual alarm that flashes red simultaneously with the sound alarm, indicating that the airflow in the hose is lower than the required 20m/s. This typically happens when the collection bag needs to be changed or the filter needs cleaning or the hose is clogged. This way the new remote control helps contribute to a safer work environment.
Sprintus flaunts high end dust control and cleaning solutions at bauma
Sprintus GmbH, a German based supplier of dust management and cleaning solutions, used bauma to showcase its flagship products - the pump vacuum N 51/1 KPS and the brand new ‘CraftiX’ series of safety vacuum cleaners. Capable of pumping out water from any flooded building structure, the N 51/1 KPS can also be used in civil engineering applications such as flat roof renovation and pool cleaning. Featuring a 900W integrated pump with a capacity of up to 14,000l/h of wastewater and a robust 50l container made out of impact proof plastic, the N 51/1 KPS is designed for challenging professional tasks. A filter net retains leaves, wood chunks and other objects in the container and prevents the pump from clogging. Thanks to a 10m wastewater hose, waste water is continuously drained from the container. With a maximum suction of 230bar and a 360mm wet floor nozzle, the machine can also function as a wet vacuum cleaner.
The new CraftiX series consists of the four certified safety vacuum cleaners designed for ‘L’ and ‘M’ dust classes. All machines feature automatic filter cleaning, which, thanks to the patented Hepa 13 cartridge filter, takes place at a constantly high suction power. This allows users to perform sawing, drilling, milling or grinding tasks in a safe and efficient manner. The CraftiX 35 L and 50 L vacuum cleaners are suitable for dealing with L class dust, which is slightly hazardous to health. If hazardous dust of M class is involved, the CraftiX 35 M and 50 M models are a better fit. Due to their standard antistatic equipment, they can easily extract large quantities of fine dust directly from the power tool. The M models are also equipped with an alert system that monitors the suction power. The operator is alerted by acoustic and visual signal if the required airflow is not reached. The heart of the CraftiX is the Hepa 13 cartridge filter. It consists of the two independent chambers, which are cleaned one after the other. Filter cleaning takes place automatically every 45sec. All four models come complete with the maxi chassis featuring large wheels and swivel casters suitable for construction sites. Thanks to their 10m power cord and 5m suction hose, the CraftiX vacuums provide a large operating radius on any construction or demolition site. All models are equipped as standard with a 450mm dry floor nozzle, a crevice, a round nozzle and power tool adapters. Established in 2007, Sprintus GmbH is a family owned manufacturing company located in the town of Welzheim in Baden-Württemberg, some 35km from Stuttgart.
