International. According to Greenheck, the two new solutions belong to the MultiSPECTM SP-LP line and have features that allow them to offer high performance.
The SP-LP0511H features a built-in sensor that helps monitor humidity to prevent mold and mildew with speed selections of 50/80/110 cfm. In addition, the SP-LP0810W model features two-speed operation for continuous ventilation throughout the home (range 30 to 100 cfm) to meet the requirements of ASHRAE 62.2.
Both models are available in illuminated configurations and are compatible with the CRD-300WT, a UL 263 certified ceiling radiation damper.
Greenheck SP-LP ceiling pullers are powered by an electronically commutated motor (ECM) with adaptive variable speed technology and constant CFM, programmed to overcome the static pressure associated with common commercial, multifamily, and residential installations (0.4 inches wg and above).
The engine reacts to increased static pressure by increasing its speed to supply the airflow needed to remove harmful air and moisture and meet the latest energy codes.
Offering quiet operation in a low-profile design, SP-LP fans are ideal for multi-family installations with a 3.5" enclosure depth that allows for wall or ceiling installations and easily fits into a 2×4 stud compartment.
Greenheck further noted that with an airflow of up to 110 cfm, the MultiSPECTM SP-LP fans are the most powerful low-profile extractor fans on the market.
