PPS – Peripheral Side Swing

The side-swing PPS model is the recommendation of choice for all return access panel applications. The peripheral return air opening between the frame and the door makes for a sleek and modern design that appeals to the eye. The access door has acoustical lining to absorb internal noise and attenuate its transmission to the living area. It also provides access for filter change and for retrieval of the unit’s compressor chassis for maintenance. Three standard frame profiles provide three choices of width for the peripheral return air opening namely PPSA (1.1” wide), PPSB (1.6” wide), PPSC (2.1” wide), allowing the designer to adjust the free area to the capacity of the heat pump.
