LPA Series F Plate Axial
The Luft series ‘F’ plate axials are an established range of high quality bellmouth plate mounted fans. Designed for either wall or duct mounting, these air movers are engineered to high tandards having excellent volume/power characteristics. The range covers 15 models in sizes from
315mm to 630mm. Two standard speeds, 920rpm and 1440rpm (nominal) are available and can be supplied with single or three phase motors.
The fans come fully assembled and are tested before delivery. The motor is supported by a rigid powder-coated wire guard, which is fixed to a glass fibre bellmouth plate. The guard supports the
motor and doubles as a protection screen to avoid accidental contact with the rotating impeller and prevents airborne objects from passing through the fan. The guard is fixed to the plate via secured rubber mountings to ensure vibration free operation. The polypropylene impeller with true aerofoil section blades delivers maximum output with low noise levels. The centre hub is die
cast in aluminium or GRN and fixed to the motor shaft by a retaining washer and high tensile bolt.
The legend plate showing the fan details is fixed to rear of the motor for easy reference.
Manufactured essentially from corrosion proof materials, all fixings are electro galvanized. The fibreglass plate, together with the polypropylene blades and powder coated protection guard ensure the highest degree of anti-rust protection for the fan assembly.
Extruded aluminium air stream motors of robust design are generously sized to match the impeller diameter. Class ‘F’ insulation with IP55 protection is standard throughout the range ensuring protection against moisture and industrial atmospheres. Bearings are sealed and are to SABS and IEC standards. The motor temperature range is from –20ºC and 40ºC. All fans have
standard metric frame motors.
