The Filter Media Cabinet (FMC) is just for applications that have space constraints and can be used with a return drop or installed over a floor return plenum. Filter depth is standard (nominal 25”). FMC boxes come in two models that will fit 1” 2” or 4” filters. The 4” tall box can house a 1” or 2” filter while the 8” tall box fits a standard 4” filter. Options include front load or side load. The front load has the filter door on the short side of the box and side load models have the door on the long side of the box.
