SLC400 Revolution Long Cased Axial Fan Three Phase AC 400mm

The Elta SLC400/4-3AC is a 400mm Revolution long cased axial fan and the 400mm four pole three phase model. It moves up to 4968 m³/h at free air and 3780 m³/h against 100 Pa, from a 4 pole three phase AC motor running at 1425 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-TC33 transformer controller. Elta give a 12 month warranty. 3 Phase AC Motor Up to 4968 m³/h Speed Controllable What it is best used forModerate airflow three phase ventilation: workshops, small warehouses, plant rooms, school and sports facilities and farm buildings, wall mounted or on duct runs up to 100 Pa. It moves 4968 m³/h at free air, roughly 10 air changes an hour in about 496 m³, at 53 dB(A) at 3m.At 100 Pa it is down to 3780 m³/h, so it is not for long filtered systems. Above that pressure, step up to a 450mm fan.Why choose this over alternativesIt moves about 17% more air than the single phase Elta SLC400/4-1AC (4234 m³/h) and can be transformer or inverter controlled. The Elta SLC450/4-3AC is the next step: 6991 m³/h and a curve to 150 Pa on 0.491 kW.For a lighter compact case at the same size, the Elta SCD400/4-3AC moves 4993 m³/h but only to 75 Pa.Installation notes Mount at any angle, horizontally in a duct run or vertically, and make sure the fan is adequately supported: it weighs 34 kg. AV mounts and mounting feet are available from Elta. The flanges are 475mm outside diameter with 8 holes of 12mm on a 450mm 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.
