The propeller fan needs little introduction having given admiral service for over half a century. Probably the most reliable, robust and versatile air mover available, the LUFT Series FAC / FTAC propeller fan continues to meet the demand for a competitive, easy to install ventilation fan, available in thirteen models delivering volume flow rates of 0,22m³ to 4,00m³ per second with pressures up to 130 pascal, the propeller fan is no doubt the most cost effective fan for moving large volumes of air at low pressures.
The complete fan assembly is mounted on an octagonal pressed steel mounting plate. Produced in six diameters 230, 300, 400, 450 and 600mm, the impeller comprises four heavy gauge pressed steel blades bolted to the die cast aluminum alloy hub.dynamically balanced after assembly. Four rigid mild steel arms are provided for fixing the motor and impeller to the mounting plate by way of special vibration absorbers. Each model is supplied complete with a motor side wire guard providing protection against accidental contact with the blades whilst the impeller is in motion and preventing air borne objects from passing through the fan.
Totally enclosed motors specifically designed to match their respective impellers are protected to IP54 standard, with sealed for life ball bearings to BSZETB/1970. Standard motors are suitable for operation in ambient temperatures between -20 C and 4O“C in relative humidity up to 95%. All 220 volt models are supplied with a one metre electrical cord, which may be connected to a 15 amp switch socket or a suitable isolator at the fan.
The 380 volt models are not supplied with an external electrical cord. Motors exposed to the weather or other arduous conditions may require further treatment. The highest degree corrosion resistance is ensured by phosphoric cleaning and double dipping all steel and alloy components in resin based paint. Bolts, nuts and other fixings including the motor side wire guard are electro-galvanized. An epoxy resin impeller side guard may be fitted as an optional extra. the product carries a one year warranty.
