The Multipurpose High-Performance Solution
Our code-compliant-verified ventilation fans help ensure that you meet code, exceed your customers' expectations, and eliminate costly callbacks.
Exclusive Features
- 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 and meet the latest energy codes.
- Greenheck's code-compliant-verified ventilation fans are all tested and certified (air & sound) for 0.4 in. wg and above, so there are no surprises. You get the airflow that you paid for and eliminate callbacks.
- The SP-LP series is the most powerful low-profile exhaust fan on the market, offering airflow up to 110 cfm.

Additional Benefits
- The virtually silent EC motor features three built-in high-speed airflow settings of 50, 80, and 110 cfm.
- 3 1/2-inch housing depth – the low profile is ideal for wall or ceiling installations, and easily fits in a 2x4 stud bay.
- L-shaped bracket for support and ease of installation.
- UL listed for tub/shower enclosure when GFCI protected.
- SP-LP0511L includes a 10W dimmable LED chip panel, 750 lumens, 3000K warm white color temperature, and Rated Life of 50,000 hours.
- 3-year warranty on EC motor and parts, excluding light.
