Ideal for clean environments, filter fan packages use densely filtered, ambient air to pressurize enclosures so air cannot be drawn-in through poorly sealed doors, panels and wireway. This protects electronics from both heat and condensation. Filter Fan Package includes the fan with grille, filter and filter sealing gasket. Exhaust Grille Kits are offered for each Filter Fan Package and must be ordered separately. Filter sealing gaskets are supplied with both Filter Fan Package and Exhaust Grille Kit to achieve an IP54 rating. Simple, snap-in mounting. Slim fan grille protrudes only .25 in. or less from enclosure mount. Fan is completely installed inside plastic housing. Removable grille cover. Mounting hardware, full-size mounting template, drawings and installation instructions furnished. Housings are made of heat resistant, self-extinguishing ABS; color RAL 7042 grey (grille only).
