SLC315 1EC Revolution Long Cased Axial Fan Single Phase EC 315mm

The Elta SLC315-1EC is a 315mm Revolution long cased axial fan with a single phase EC motor. At full speed it moves up to 1753 m³/h at free air and 677 m³/h against 150 Pa, with the speed fully variable from a 2 to 10V signal, 4 to 20mA, PWM or a potentiometer.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 IE5 EC motor has its variable speed drive built in, is IP55 with sealed for life bearings, runs on 220-277V 50/60Hz and is rated for air up to +60°C. Elta give a 12 month warranty. 1 Phase EC Motor Up to 1753 m³/h Speed Controllable What it is best used forVariable speed ventilation on a single phase supply where running cost and control matter: plant rooms, small workshops and stores. It moves 1753 m³/h at full speed (10V) and can be turned down with a 2 to 10V signal, 4 to 20mA, PWM or a potentiometer to match the actual demand.At full speed it reaches 150 Pa (677 m³/h at that pressure). It is not for explosive atmospheres (use the ATEX SLCX range), and it must be disconnected before any insulation resistance testing, which can damage the electronics.Why choose this over alternativesAgainst the AC Elta SLC315/4-3AC (1440 m³/h, to 75 Pa), the EC model gives stepless speed control without a separate transformer, an integrated drive and an IE5 motor, with 45.2% overall fan efficiency at its best efficiency point. The AC fan is the lower cost choice where fixed or stepped speed is enough.Need more air? The Elta SLC355-1EC moves 2254 m³/h at full speed and reaches 150 Pa.Installation notes Mount at any angle, horizontally in a duct run or vertically, and make sure the fan is adequately supported: it weighs 15 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. Allow at least 5 minutes between switching the supply off and on: the motor has a delayed start and should not be cycled at the isolator. Day to day control should be by the speed control input or controller. Disconnect the fan before any insulation resistance testing, as it can damage the EC electronics. The terminal box takes one 20mm and one 25mm conduit fitting. Wire to diagram 152-710 or 152-736 as shown on the product label. The motor has an auto reset thermal contact, so isolate before maintenance as the fan may restart once cooled.
