Remove fumes from engine compartments. These are medium-duty blowers for exhausting warm air, ventilating odors or steam and general marine air circulation. 12V models are ignition protected and approved for removal of gasoline vapors from confined engine spaces.All models are constructed of tough reinforced plastic and have one-piece, balanced plastic rotors for maximum corrosion resistance. Flangemount models mount directly onto a flat bulkhead and use a mounting collar to connect to discharge ducting. Flexmount models install to any flat surface with the adjustable mounting bracket. Flexmount blowers can be rotated within the mounting collar to achieve the most convenient exhaust hose routing in confined spaces.Flangemount Blowers:Are of a radial design which gives the highest output in more complex installations with longer ducting lengths and/or multiple bends in the ducting. They are generally mounted directly onto a flat bulkhead using a mounting collar to connect to the discharge ducting. This allows a very neat installation on an engine room bulkhead.Flexmount Blowers: Are also of radial design but are installed by attaching a mounting collar around the motor (which is supplied with the blower) to any convenient solid surface. They can be rotated inside the collar to allow the shortest ducting lengths and most convenient routings in confined spaces. Both ports are designed for slipon flexible ducting connections.Key FeaturesTough, reinforced plastic housings and a one-piece balanced rotorFlexmount models have both inlet and outlet ports designed for slip-on flexible-duct connectionsFlangemount models mounted with discharge port fastened to flat surface to minimize ductingLow current drawQuiet runningApprovals USCG, ISO 8846/9097Note: Compact model is approximately 25% smaller than the regular 3" size.
