Summary
See more specification See less specification
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 for
Moderate 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 alternatives
It 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.
You'll also need
- Elta matching flanges 400mm (061B-0400) (sold each, one per ducted side)
- Elta 149-TC33 three phase transformer speed controller (available to order, ask us)
- Eltadrive 149-ODE3-14075-3KA1B inverter for a three phase supply (or 149-ODE3-12037-1KB1B from single phase; available to order, ask us)
- 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 SLC400/4-3AC 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 4968 m³/h (1.380 m³/s) at free air, falling to 3780 m³/h at 100 Pa, the highest pressure in Elta's table for this model.
Is the SLC400/4-3AC single or three phase?
Three phase, 380-415V 50Hz, star connected as supplied. Peak current is 1.02 A.
Can I control the speed of the SLC400/4-3AC?
Yes. Elta list the 149-TC33 three phase transformer controller, or an Eltadrive inverter: 149-ODE3-14075-3KA1B on a three phase supply or 149-ODE3-12037-1KB1B from single phase (motor reconnected to delta, per the installation manual).
How noisy is it?
53 dB(A) at 3m in free field, per Elta's data. Elta offer podded and unpodded silencers in 1D and 2D lengths 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.
