SLC450 1EC Revolution Long Cased Axial Fan Single Phase EC 450mm

The Elta SLC450-1EC is a 450mm Revolution long cased axial fan with a single phase EC motor. At full speed it moves up to 5911 m³/h at free air and 2340 m³/h against 250 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 5911 m³/h Speed Controllable What it is best used forVariable speed ventilation on a single phase supply where running cost and control matter: kitchen canopy systems, workshops and sports facilities. It moves 5911 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 250 Pa (2340 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 SLC450/4-1AC (6059 m³/h, to 100 Pa), the EC model gives stepless speed control without a separate transformer, an integrated drive and an IE5 motor, with 61.7% 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 SLC500-1EC moves 8147 m³/h at full speed and reaches 200 Pa. Stepping down, the Elta SLC400-1EC moves 4241 m³/h.Installation notes Mount at any angle, horizontally in a duct run or vertically, and make sure the fan is adequately supported: it weighs 30 kg. AV mounts and mounting feet are available from Elta. The flanges are 530mm outside diameter with 8 holes of 12mm on a 500mm 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.
