FlexFilter12 1


Modular designed dust collector

Dust collector with 2-stage filtration. Central inlet with velocity reducer. Fully automatic filter cleaning. Can easily be equipped with a great variety of filter materials, bins, emptying systems, etc. Standard equipped with circular bags of polypropylene. PTFE or antistatic filters on request.

A state of the art filter system to meet your current and future needs

The Flexfilter EX is manufactured to withstand overpressure from a potential explosion and is equipped with an explosion relief panel. The harmful effects of an explosion are minimized by venting the overpressure and flame propagation via the relief panel to a safe area. The dust collector is fully earth bonded in all modular components. All electric equipment is EX classified for combustible dust. Options are available for the collected dust from either a standard 70L (18 gal) collection bin complete with bin balance kit to allow the use of conductive plastic sack for ease of removal of the collected dust or fully automatic empty device with fully conductive bulk bag with earth cables for larger installations. A control filter comes as standard to allow the use of non-EX rated vacuum units.
