Summary
See more specification See less specification
The Elta SLC400-1EC is a 400mm Revolution long cased axial fan with a single phase EC motor. At full speed it moves up to 4241 m³/h at free air and 3132 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 4241 m³/h
- Speed Controllable
What it is best used for
Variable speed ventilation on a single phase supply where running cost and control matter: kitchen canopy extract, workshops and school spaces. It moves 4241 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 (3132 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 alternatives
Against the AC Elta SLC400/4-1AC (4234 m³/h, to 100 Pa), the EC model gives stepless speed control without a separate transformer, an integrated drive and an IE5 motor, with 61.1% 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 SLC450-1EC moves 5911 m³/h at full speed and reaches 250 Pa. Stepping down, the Elta SLC355-1EC moves 2254 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 25 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.
- 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.
You'll also need
- Elta matching flanges 400mm (061B-0400) (sold each, one per ducted side)
- Elta EC electronic controller 149-POT-10-MI (the controller Elta list for this model)
- Elta APK400/003 ancillary pack (flexible connections, matching flanges, AV mounts and mounting feet in one code; available to order, ask us)

What size duct does the Elta SLC400-1EC fit?
It is a 400mm fan with 400mm inside the casing. The flanges are 475mm outside diameter with 8 holes of 12mm on a 450mm PCD, and the case is 400mm long.
How much air does it move?
Up to 4241 m³/h (1.178 m³/s) at free air at full speed, falling to 3132 m³/h at 150 Pa, the highest pressure in Elta's table for this model.
Is the SLC400-1EC single or three phase?
Single phase, 220-277V at 50Hz or 60Hz. Peak current at full speed is 2.54 A.
How do I control the speed of the SLC400-1EC?
The drive is built into the fan. Elta list the 149-POT-10-MI EC electronic controller, and the fan also accepts 2 to 10V DC, 4 to 20mA or a 10 to 95% PWM signal from a BMS or sensor. A 149-CD-POT commissioning device on the fan sets the maximum speed.
How noisy is it?
55 dB(A) at 3m in free field at full speed, per Elta's data, and much quieter when turned down. Elta offer 1D and 2D silencers for this size if you need it quieter.
Can it be mounted outside or vertically?
Yes. The galvanised casing is suitable for external mounting as standard and the fan can be mounted at any angle. For explosive atmospheres you need the ATEX rated Elta SLCX range instead.
