Ventilation grilles with a dust cover - the VF series

VENTILATION GRILLES WITH DUST COVER - VF SERIES

Description:
Our VF series of covers combines the benefits of ventilation attenuation panels with the properties of dust filters in a single frame, unlike the VB series of covers, which use separate elements bonded together in-situ.
Standard frame types are AF1, AF2, AF3, AF4, AF6, AF7, and AF8. They incorporate a triple layer of corrugated woven aluminum mesh. Each layer has a slightly different degree of corrugation, providing separation and greater airflow potential. To perform its dual function, the VF filter media is relatively dense, requiring assisted airflow to function properly. A protective plate is incorporated into the device to protect the filter from damage.

Application:
Aluminum mesh dust filters are assembled in the same manner as VH shrouds and are used in industrial or military environments where a heavy-duty, attenuating dust filter is required and the lighter, membraneless polyurethane VB shroud is not suitable. They are not designed for pure convection and require driven airflow. They can be cleaned with solvent after disassembly, but special care should be taken to replace seals, which can fail due to compression or hydrocarbon/solvent contamination.
