Amist20 is available with different filter cassettes depending on the application and are designed for air flows up to 2000m³/h. The filter units are being placed adjacent to one or several machines. The Amist20HP version can even cope with longer duct lengths and thereby higher external pressure drops.

Per utilizzo


The highest possible collecting efficiency

The filtered air becomes so clean that it usually can be returned to the premises. This means less loss of energy and a more balanced ventilation.

Extremely low maintenance

Absolent filter units can usually run for at least one year without requiring a filter change. Moreover, Amist filter cassettes can usually be washed**. This results in a low total cost of ownership.

A very reliable filter unit

The fan, as the only moving component, is placed at the clean-side to minimize wear & tear.
Extremely low noise level for agreeable working conditions.

Functional Design

The Amist filter range has a highly robust tower design that occupies a minimum of floor space. Its hinged access doors make service still more convenient. The filter is supplied with a baked powder painted finish that adds colour to the shop floor.


The filtering process occurs in three stages. The process air passes first through the self-draining Absolent filter cassettes. Here, approximately 90% of the oil mist is arrested. The last stage consists of a HEPA filter, which has a guaranteed and consistent collecting efficiency of 99.97% arresting 0.3 μm dia. particles. The filter unit has an electronic pressure gauge, Amonitor, which shows the pressure drop over the different filter stages and indicates when a filter cassette is to be changed. Thanks to the continuous draining of the filter cassettes, the unit can be operated without interruptions. The return oil is collected at the bottom of the filter for recycling.
