Ultra-thin ventilation grill / honeycomb / EMC

General Information :

VT thin vent panels are effectively slimmer versions of the VF airfilters but with different filtration media. The VT series comprises two basic types referred to as A & B.

VT(A) panels incorporate an expanded aluminium mesh which is crimped into an aluminium extrusion frame. The VT(A) style offers excellent dust filtration and RF shielding performance but considerably restricted airflow.

The VT(B) styles utilise a lower profile extruded aluminium frame (3.5mm) than the VT(A) into which a woven aluminium or expanded Monel foil is crimped.


Applications :

VT thin vent panels are designed for enclosures or racks where RF attenuation and protection from the ingress of foreign bodies is required but space is at a premium.

VT(A) panels are nominally 6.0mm thick inside a 4.8mm thick frame and provide attenuation levels considerably higher than the VT(B) types which have a very small effect on airflow but offer less shielding effectiveness.

VT(A) & VT(B) shielding materials have very different properties and their airflow characteristics are a function of size, positioning, application and airflow source / volume. We suggest that a sample of the materials is requested for customer testing before specifications are finalised - please ask our sales office.
