ATI-Thin Filter

ATI-Thin Filter is the thinnest profile EMI shielded air filter. Extruded aluminum surrounds a singular thin piece of expanded monel or aluminum metal screen and welded in place. Alco-Knit or conductive gasket increase shielding effectiveness. Through hole locations are customized for easy surface mount installation. Plating options enhance shielding effectiveness. ATI–Thin Filters are frequently placed at intake and exhaust areas and are best utilized where narrow space limitations are a requirement.
