Product focus:

Roto-cleaning filter unit type FR3

The FR3/VT500 filter unit is suitable for small process extraction tasks such as dust extraction from small grinding machines, sandblasting cabins and the like. The filter unit is suitable for both dust and chips and ensures both high separation efficiency and long filter life thanks to the Roto-cleaned cartridge filter. The unit can be supplied without a fan for connection to a central system or with a built-in fan and exhaust silencer for independent operation and recirculation.

"In connection with centralized welding fume extraction systems, the duct systems are dimensioned with low transport speeds to reduce energy consumption, but when grinding machines are connected, the transport speed in the main duct will not be sufficient for cleaning. In this case, it is a good idea to install an FR unit directly after the grinder so that grinding dust and chips are not directed into the main duct. This ensures continued clean duct systems for the benefit of energy consumption and minimizing the risk of fire."
