The VARIO series is particularly suitable for separation of fine dust. Nearly all types of dust can be successfully separated, such as those created in metal processing, polymer processing, and in chemical, pharmaceutical and ceramic industries, as well as non-metallic minerals.


The dust-laden air flows through the dirty air inlet into the filter unit.

A baffle plate slows down and deflects the dust particles to protect the filter elements from direct impact. An air down-flow is created between the filter elements, allowing the dust particles to drop. A fan in the clean air chamber draws the polluted air through the filter elements, depositing the dust particles onto the filter surface.

Because the filter elements are cleaned continuously by compressed air pulses during operation, the air flow remains constant. The cleaned air exits through the top of the unit and in most cases can be re-circulated into the work area or vented outdoors. The separated dust falls into the dust collector containers

Filter Elements

Cartridges or plate filters are used, depending on the application, for enhanced separation efficiency and service life. All filter elements used are of high quality and easy to clean.

Cleaning of the filter elements

The pulse cleaning cycle can be adjusted for each application by means of an integrated control unit. The air flow of the fan remains nearly constant. The cleaning operation is activated either by a differential pressure regulator while in operation, or by a programmable downtime cleaning cycle.
