SLC500 Revolution Long Cased Axial Fan Three Phase AC 500mm

The Elta SLC500/4A-3AC is a 500mm Revolution long cased axial fan and the smaller motor four pole three phase model at 500mm. It moves up to 6494 m³/h at free air and 3884 m³/h against 150 Pa, from a 4 pole three phase AC motor running at 1435 rpm.The casing is heavy gauge steel, hot dip galvanised to BS EN ISO 1461 and suitable for external mounting, with a die cast aluminium aerofoil impeller. The motor is IP55 with sealed for life bearings, wired to an IP55 terminal box on the outside of the case. The IE2 motor is designed for use with a frequency inverter and can also run on a 149-TC310 transformer controller. Elta give a 12 month warranty. 3 Phase AC Motor Up to 6494 m³/h Speed Controllable What it is best used forLow to moderate pressure ventilation on three phase where 500mm ducting is fixed: warehouses, workshops, sports halls and agricultural buildings, wall mounted or ducted up to 150 Pa. It moves 6494 m³/h at free air on only 0.39 kW, at 53 dB(A) at 3m.It drops to 3884 m³/h at 150 Pa. If the system sits near that pressure, the SLC500/4B-3AC holds far more air.Why choose this over alternativesThe Elta SLC500/4B-3AC in the same casing moves 8075 m³/h at free air and 6437 m³/h at 150 Pa on 0.689 kW. Choose the 4A for lower resistance systems where it is cheaper to run.Worth comparing: the smaller Elta SLC450/4-3AC moves 6991 m³/h and holds 4601 m³/h at 150 Pa, so if the duct size is not fixed it can be the better fit.Installation notes Mount at any angle, horizontally in a duct run or vertically, and make sure the fan is adequately supported: it weighs 33 kg. AV mounts and mounting feet are available from Elta. The flanges are 585mm outside diameter with 12 holes of 12mm on a 560mm PCD. Use Elta matching flanges and flexible connectors to join it to ductwork. Fit a local isolator, and protect the motor with a starter or controller that has overload protection; fuses and breakers only give short circuit protection. Do not use the isolator for day to day on and off control. Supplied star (Y) connected for a 400V three phase supply, wiring diagram 152-600. The installation manual shows it reconnected to delta when run from a single phase to three phase inverter. Not suitable for corrosive or explosive atmospheres. Inspect and clean the impeller, motor and guards at least every 12 months.
