SLC630 4A 3AC Revolution Long Cased Axial Fan Three Phase AC 630mm

The Elta SLC630/4A-3AC is a 630mm Revolution long cased axial fan and the most efficient model at 630mm. It moves up to 13403 m³/h at free air and 8561 m³/h against 250 Pa, from a 4 pole three phase AC motor running at 1475 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. Elta give a 12 month warranty. 3 Phase AC Motor Up to 13403 m³/h Speed Controllable What it is best used forEfficient general ventilation and ducted extract on three phase up to 250 Pa: warehouses, distribution sheds, factories, sports halls and agricultural buildings. It moves 13403 m³/h at free air, roughly 10 air changes an hour in about 1340 m³, at 64 dB(A) at 3m.The table stops at 250 Pa (8561 m³/h). For more air in 630mm ductwork choose the SLC630/4B-3AC.Why choose this over alternativesIt has the best overall efficiency of the 630mm SLC models (48.8%, FMEG 54). It moves about the same air as the Elta SLC560/4C-3AC on 1.13 kW instead of 1.497 kW, so if 630mm ducting fits, it is the cheaper fan to run.For more volume at this size, the Elta SLC630/4B-3AC gives 20243 m³/h at free air on 2.24 kW.Installation notes Mount at any angle, horizontally in a duct run or vertically, but make sure the fan is adequately supported: it weighs 47 kg. AV mounts and mounting feet are available from Elta. The flanges are 715mm outside diameter with 12 holes of 12mm on a 690mm 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.
