Greenheck Introduces the Modular SP-AP Ceiling Exhaust Fan
November, 2019

The latest advance in Greenheck’s line of SP commercial ceiling exhaust fans is the modular SP-AP fan that offers exceptional design versatility and energy efficiency. The SP-AP’s constant CFM EC motor technology ensures performance set points resulting in improved indoor air quality when application static pressure is higher than expected. The SP-AP is two speed capable (constantly on low speed) with built-in time delay. Three built-in high-speed airflow settings of 50, 80 and 110 cfm meet most common applications. Plug-and-play sensor modules (motion, humidity, CO2, and night light) enable easy customization. A universal duct connector for 4”, 5” and 6” ducting along with an install bracket and room side-duct connection allows for simple, quick installation in both new construction and retrofits. Certified as an Energy Star Most Efficient 2019 product, the SP-AP is ideal for multifamily applications such as condominiums, apartment buildings, hotels, and senior living facilities.
