Products: Attenuation Vents with Dustfilters | VF Series

General Information

Our VF Series of RFI vents combine the benefits of an attenuation vent panel with the properties of a dustfilter in a single frame, unlike the VB Series which utilises separate units fixed together in-situ.

Standard frame styles are AF1 to AF4 and they incorporate a triple layer of woven and corrugated aluminium mesh. Each layer has a slightly different degree of corrugation and so provides separation and increased airflow potential. To enable it to perform its dual function the VF filter material is relatively dense and so requires an assisted airflow to operate correctly. A 'kickplate' is built into the unit to protect the filter from damage.

Applications

VF dustfilters are mounted in the same manner as the VH series and are used in industrial or military environments where a 'heavy duty' attenuating dustfilter is required and the lighter weight de-membraned polyurethene VB Series is not suitable. They are not designed for pure convection and need a driven airflow. They may be solvent cleaned after removal but particular attention should be paid to the replacement of gaskets which could be affected by compression-set or hydrocarbon/solvent contamination.
