MODEL OVERVIEW
S&P’s Model CM is available in a full range of sizes (10 through 36) provides airow performance from 500 CFM to over
24,500 CFM with static pressure up to 5.5 in. w.g. This single inlet backward inclined utility fan provides substantial benets
for pressure ow, low power consumption and low noise level, ideal for commercial and industrial applications. Typical
applications include either supply or exhaust service for ducted systems in schools, theaters, gymnasiums, manufacturing
plants, hotels, ofce buildings, restaurant hoods, and many other general ventilation applications.
The turbine performance, minimizes unnecessary energy losses resulting in a system with high efciency.
Its design, manufacture and testing guarantee a long operating life with low
maintenance. Also having great versatility in arrangements, and available
positions with a complete series of mounting accessories for installation and
proper operation of equipment for each application.
The mechanical design and construction determines the maximum operating
speed and power. The performance ranges shown on the following pages
comply with the Class I operating limits as dened in AMCA standard 99.
