G-FIL
G-FIL shielded air vents offer a high grade of shielding effectiveness against the penetration or emissions of high frequency interferences of all kinds through air vents of otherwise shielded housings. The air flow resistance is very low. A G-FIL air vent consists out of a aluminium honey comb bordered by a frame. Honey comb and frame are made out of a hard aluminium alloy. The frame of the vent is delivered with fixing holes or tapped through holes to fasten the air vent to the housing. The frame normally has a gasket to seal the space between the frame and the housing. The air vents are usually produced by specifications of the customer. Possible forms are round and rectangular. Frames manufactured out of aluminium are usually used for rectangular profiles. Round vents are hold by two round profiles.
