Advanced
technology, high quality products
and in-depth application expertise combine
to provide cost effective solutions
to EMI/RFI shielding challenges.
Shielded Screen Filter Ventilation
Panels Special air filter panels, with knitted metal
screen mounted behind a retaining grill in a similar type edge frame, are
available for filtration of dust particles at the air intake of electronic
enclosures which require low velocity filtered cooling air
while, at the same time, providing
effective EMI/RFI shielding.
General:
Shielding Express Inc. Shielded Screen Filter Ventilation Panels are
constructed using multiple layers of aluminum screen mounted within a C-channel
edge frame. The panels are supplied ready to mount on the shielded enclosure
via a composite EMI/RFI shielding gasket attached to the panel frame. The panel
edge frame has a mounting hole pattern for either through bolts or captive
insert receptacles. This type of filter panel is
normally used for air
filtration.
All panels are made to customer specifications.
