Our EMI Shielded vents with dustfilter assemblies are composites of our EMI Shielded honeycomb attenuated vents and removable dustfilter panels containing a demembraned polyurethene filter media. The attenuated 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 honeycomb 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.
Honeycomb vent and demembraned polyurethane dust filter panels 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 woven aluminium mesh is not needed. Dust filters fitted inside the equipment can have quick-release fastenings and do not require an emi shielded gasket. In applications where the attenuated vent is fixed directly to the enclosure, dustfilters mounted outside the equipment do not need an emi shielded gasket.
