The F17HA fan also has an optional on-board speed signal. The F16BJ brushless blower develops a maximum air flow of up to 1.24 CFM at a static pressure of 0.056 in. of water. The blower is available with ball and sleeve bearings, depending on application, and is designed for intermittent “spot” cooling applications.
