Applications

The Polyfoam Washable filter is a medium efficiency filter suitable for ventilation and air conditioning systems, where cleanability is required rather than a disposable cell.

These filters are initially more expensive than disposable panels, but can last several years.

Use of washable filters makes it unnecessary to have valuable space-consuming spares on the premises, and also obviates the need for frequent ordering of replacements.

Description

The filter media is reticulated polyurethane foam, enclosed within an aluminium channel frame with a galvanised retaining mesh on the outlet face. The frame is provided with corner gussets to provide added rigidity.
