SLC315 Revolution Long Cased Axial Fan Three Phase AC 315mm

The Elta SLC315/4-3AC is a 315mm Revolution long cased axial fan and the smallest model in the Revolution SLC range. It moves up to 1440 m³/h at free air and 929 m³/h against 75 Pa, from a 4 pole three phase AC motor running at 1485 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 1440 m³/h Speed Controllable What it is best used forSmall, low pressure three phase duties that need an industrial build: plant room and switch room ventilation, small workshops, stores and farm buildings, on short duct runs or through the wall. It moves 1440 m³/h at free air on 0.121 kW and is very quiet at 40 dB(A) at 3m.Its table stops at 75 Pa (929 m³/h), so it is only for short, low resistance runs. If you need more pressure in 315mm, the SLC315-1EC reaches 150 Pa.Why choose this over alternativesAgainst the Elta SLC315-1EC in the same size, this AC model suits sites that already run three phase plant and want a 149-TC33 transformer or Eltadrive inverter. The EC model moves more air (1753 m³/h at full speed) from a single phase supply.For a lighter compact case, the Elta SCD315/4-3AC moves 2102 m³/h but only to 25 Pa; the SLC has more casing length and a galvanised finish suitable for external mounting. If you need more air, step up to the Elta SLC355/4-3AC.Installation notes Mount at any angle, horizontally in a duct run or vertically, and make sure the fan is adequately supported: it weighs 16 kg. AV mounts and mounting feet are available from Elta. The flanges are 375mm outside diameter with 8 holes of 10mm on a 355mm 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.
