Products: EMC Vent / Filter Composites | VB Series

General Information

Our VB Series of EMC vents / filter assemblies are composites of the VH Series honeycomb attenuation vents and demountable dustfilter panels containing a demembraned polyurethene filter media. The vent is specified in the normal way and contains, within its mounting frame, additional fixings (usually captive threaded inserts) which are used to retain the framed dustfilter element.

The dustfilter can be mounted either side of the EMC vent panel and attention should be paid when specifying the type of interface gasket to ensure that, where necessary, it is conductive. The filter material is available with openings of 30 to 60 per inch as standard, but others can be specified, and is secured by a woven mesh kickplate.

Applications

VB Series EMC vents are usually used inside racks and electronic equipment enclosures, in particular where the ingress of dust or foreign matter is likely but the heavier duty VF Series is not needed. Filters fitted inside the equipment can have quick-release fastenings and do not require a shielded gasket. In applications where the attenuation vent is fixed directly to the enclosure, dustfilters mounted outside the equipment do not need a shielded gasket.
