The spare part number for the filters is W0M-74350. The part number W0M-74530 ships as 1 box of 5 filters. 5 filters are required per unit.
The filtration of conditioned air is extremely vital to maintaining the clean, particle-free environment required by electrical equipment. The system uses 30% efficient (100 microns) (ASHRAE 52.1-92), 4” (102 mm) deep filters, with full depth filter pleats. Deeper filters produce a lower pressure drop, requiring less energy during normal operation. Filters are replaceable through the front of the upflow unit, and through the top of the downflow unit.
