MULTISPEC SP-LP Series is powered by an electronically commutated motor (ECM) with Constant CFM adaptive, variable speed technology programmed to overcome the static pressure associated with common residential installation scenarios (0.4 in. wg and above). The motor reacts to increased static pressure by increasing its speed to ensure you have the airflow required to remove unhealthy air and moisture.
Key features: ENERGY STAR rated, virtually silent EC motor with 3 high speeds (50-80-110 CFM), constant CFM technology, 3-1/2-inch housing depth – the low profile is ideal for wall or ceiling installations, easily fits in a 2x4 stud bay, L-shaped bracket for support and ease of installation, ETL listed for tub/shower enclosure when GFCI protected, 3-year warranty on ECM motor and parts.
Model SP-AP features a virtually silent electronically commutated (EC) motor with three built-in, high-speed airflow settings (50, 80 or 110 cfm). Its standard two-speed operation (commonly known as whole house) helps comply with ASHRAE 62.2, WSEC, and CAL Title 24 requirements. Fan features allow for improved performance in a variety of installations, improved indoor air quality and the elimination of issues during test and balance.
Key features: ENERGY STAR® rated, virtually silent EC motor with 3 high speeds (50-80-110 CFM), constant CFM technology, plug and play sensors available (Humidity and CO2), 4”, 5” or 6” duct connector, easy installation bracket, two speed capable with integral time delay.

The CRD-300WT series dampers are classified to function as a heat barrier in air handling penetrations through fire resistive membrane ceilings. They are intended to maintain the fire resistive integrity of the ceiling. They can only be installed in conjunction with the SP-AP or SP-LP fan models shown and cannot be installed alone.
