Our next generation series of fans, the PPF (positive pressure fan) is the most versatile series of fiberglass exhaust and positive pressure fans. Designed with an aerodynamic one piece interior venture that can be positioned inside an insulated shroud, with insulated power shutters or a gravity shutter. Easy access hinged safety guard on the rear and fixed guard between the shutter and the blade for added protection.
The PPF fans have protected insulated shutters and do not use large costly cones to improve performance in a test lab which could have severe detrimental effects in windy real life conditions. The PPF fan is protected by a strong intake guard that is zinc coated and then painted making it very corrosion resistant. The belts can be easily removed by slipping them over the blade.
POSITIVE PRESSURE INSULATED FAN The Positive Pressure Insulated Fan Series are ideal cold climate fans. Designed for buildings that need to be insulated from the outside weather conditions of cold in the winter and heat in the summer. The strong insulated outside shutters are powered by an actuator to keep a tight seal when not operating and a full open position for optimum performance when the fan is running.
