SLC710 4B 3AC Revolution Long Cased Axial Fan Three Phase AC 710mm

The Elta SLC710/4B-3AC is a 710mm Revolution long cased axial fan and the highest airflow SLC model we list. It moves up to 28800 m³/h at free air and 21528 m³/h against 300 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 28800 m³/h Speed Controllable What it is best used forThe biggest jobs on our SLC range: warehouse and distribution centre ventilation, factory main extract, large livestock buildings and plant cooling. It moves 28800 m³/h at free air and still 21528 m³/h at 300 Pa.At 77 kg, 4.46 kW and 73 dB(A) at 3m it is a serious installation needing a three phase supply, motor protection, solid supports and usually silencers. For pressures above 300 Pa, a two pole fan is required.Why choose this over alternativesAgainst the Elta SLC710/4A-3AC, the 4B holds its airflow far better under load: 21528 against 17543 m³/h at 300 Pa. If your system sits towards the top of the curve, the 4B is the safer selection.Compared with the two pole Elta SLC560/2-3AC (24124 m³/h on 8.42 kW), the 710/4B moves more air on about half the power, if the system pressure stays under 300 Pa and you can fit 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 77 kg. AV mounts and mounting feet are available from Elta. The flanges are 795mm outside diameter with 16 holes of 12mm on a 770mm 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. Wire to diagram 152-601 (delta connected, 380-415V three phase). Check rotation and airflow direction at first start and that the running current does not exceed the nameplate. Not suitable for corrosive or explosive atmospheres. Inspect and clean the impeller, motor and guards at least every 12 months.
