Surface mounted fans can be wall or ceiling mounted and have a centrifugal impeller designed to overcome longer duct runs. The SF90A runs continuously at trickle speed. Changing to normal speed is achieved via the pull cord or remote switch. The fan back plate can be removed and fully installed before the fan and motor assembly are fixed in place. The IP rated 44 fan can be located in Zones 1, 2 or 3.
