Summary
See more specification See less specification
The Elta SLC630/4B-3AC is a 630mm Revolution long cased axial fan and the high volume four pole model at 630mm. It moves up to 20243 m³/h at free air and 13910 m³/h against 250 Pa, from a 4 pole three phase AC motor running at 1460 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. Elta give a 12 month warranty.
- 3 Phase
- AC Motor
- Up to 20243 m³/h
- Speed Controllable
What it is best used for
High volume ventilation on three phase: large warehouses, factories, distribution centres, sports halls and agricultural buildings, ducted to 250 Pa or wall mounted. It moves 20243 m³/h at free air, roughly 10 air changes an hour in about 2020 m³.
It is 66 dB(A) at 3m and stops at 250 Pa (13910 m³/h). For higher pressure duties, a two pole fan in a smaller size is the alternative.
Why choose this over alternatives
Against the Elta SLC630/4A-3AC (13403 m³/h, 1.13 kW), the 4B adds about 6840 m³/h at free air for 2.24 kW. Pick it when the 4A's curve falls short.
For even more air at moderate pressure, the Elta SLC710/4A-3AC moves 26852 m³/h and reaches 300 Pa, but needs 710mm ductwork.
Installation notes
- Mount at any angle, horizontally in a duct run or vertically, but make sure the fan is adequately supported: it weighs 58 kg. AV mounts and mounting feet are available from Elta.
- The flanges are 715mm outside diameter with 12 holes of 12mm on a 690mm 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 630mm (061B-0630) (sold each, one per ducted side)
- Eltadrive 149-ODE3-24220-3KA4B inverter for a three phase supply (available to order, ask us)
- Eltadrive 149-ODE3-22220-1KB4B inverter for a single phase supply (available to order, ask us)
- Elta APK630/003 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 SLC630/4B-3AC fit?
It is a 630mm fan with 630mm inside the casing. The flanges are 715mm outside diameter with 12 holes of 12mm on a 690mm PCD, and the case is 400mm long (dimension C).
How much air does it move?
Up to 20243 m³/h (5.623 m³/s) at free air, falling to 13910 m³/h at 250 Pa, the highest pressure in Elta's table for this model.
Is the SLC630/4B-3AC single or three phase?
Three phase, 380-415V 50Hz, star connected. Peak current is 4.56 A.
Can I control the speed of the SLC630/4B-3AC?
Yes, with a frequency inverter. Elta list the Eltadrive 149-ODE3-24220-3KA4B for a three phase supply and 149-ODE3-22220-1KB4B for single phase, with the motor reconnected to delta as shown in the installation manual.
How noisy is it?
66 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.
