Washable filter foam – Description
Filter foam is an open-cell polyurethane foam based on polyether/polyester and can be used in filtration applications. Filter foams typically differ in pore size and in the number of pores per square inch (PPI).
POLFIL material can be used in any thickness, and the range of available pore sizes covers a wide efficiency band, in particular different porosities. The layers are bonded together in tandem to reach the required efficiency through a staged mechanism.
Applications
Pre-filter for all types of air conditioning and ventilation installations.
Benefits
- Progressive open-cell structure with high mechanical strength
- High dust holding capacity at a low pressure drop
- Washable filter, reusable
- Available in rolls or cut to size
