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

The Elta SLC630/4B-3AC is a 630mm Revolution long cased axial fan and the high volume four pole model at 630mm. It moves up to 20243 m³/h at free air and 13910 m³/h against 250 Pa, from a 4 pole three phase AC motor running at 1460 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 20243 m³/h Speed Controllable What it is best used forHigh volume ventilation on three phase: large warehouses, factories, distribution centres, sports halls and agricultural buildings, ducted to 250 Pa or wall mounted. It moves 20243 m³/h at free air, roughly 10 air changes an hour in about 2020 m³.It is 66 dB(A) at 3m and stops at 250 Pa (13910 m³/h). For higher pressure duties, a two pole fan in a smaller size is the alternative.Why choose this over alternativesAgainst the Elta SLC630/4A-3AC (13403 m³/h, 1.13 kW), the 4B adds about 6840 m³/h at free air for 2.24 kW. Pick it when the 4A's curve falls short.For even more air at moderate pressure, the Elta SLC710/4A-3AC moves 26852 m³/h and reaches 300 Pa, but needs 710mm ductwork.Installation notes Mount at any angle, horizontally in a duct run or vertically, but make sure the fan is adequately supported: it weighs 58 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.
