Hammond XFF4 4" Aluminum Replacement Air Filter, 3-Pack

The XFF4 is a package of three 4-inch replacement filters for the XF Series filtered fan box system. It is intended for maintenance crews, panel builders and facilities teams who keep enclosure cooling running and need spare filter media on hand for the XFG4 grille and filter assembly, whose drawing lists the XFF4 (package of 3) as its replacement filter accessory.

The filter media is aluminum. According to the XF Series specifications, the aluminum filter is coated with adhesive baffle surfaces that collect dust and dirt, and it can be recoated after cleaning for optimum performance. Filter Coat is listed among the series accessories. The filter grill and air filter are easily accessible and can be removed for cleaning.

As the smallest filter in the range, the XFF4 is sized for the 4-inch grille, and its drawing shows a square filter pad of 132.00 mm [5.197 in] per side. The drawing gives a thickness of 8.00 mm [0.315 in]. The package ships at 1 lbs (0.45 kg).

Within the XF Series, a filtered fan box pulls air into the enclosure while the filter grill serves as the air outlet, and each installation normally needs an additional exhaust grill and filter. Keeping a spare XFF4 pack means a loaded filter can be swapped out quickly while the removed one is cleaned. The part is RoHS compliant and REACH compliant.
