Summary
See more specification See less specification
The Elta SLC500/4B-1AC is a 500mm Revolution long cased axial fan and the larger four pole 500mm model for single phase supplies. It moves up to 9266 m³/h at free air and 6336 m³/h against 150 Pa, from a 4 pole single phase AC motor running at 1440 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. Speed control is by a 149-TC18 transformer controller. Elta give a 12 month warranty.
- 1 Phase
- AC Motor
- Up to 9266 m³/h
- Speed Controllable
What it is best used for
General ventilation on a single phase supply at low to moderate pressure: sports halls, school halls, agricultural buildings, small warehouses and workshops, wall mounted or on short duct runs. At 9266 m³/h it gives roughly 10 air changes an hour in a space of about 925 m³.
Its table stops at 150 Pa (6336 m³/h), so it is not for long ducted runs with filters or grease extract. For high pressure on single phase, the two pole 450mm SLC450/2-1AC is the alternative.
Why choose this over alternatives
It is the larger motor option to the Elta SLC500/4A-1AC, which moves 7427 m³/h at free air. The 4B adds around 1840 m³/h for 0.702 kW instead of 0.483 kW, and is still quiet at 56 dB(A) at 3m.
Unusually, this single phase fan out-performs the three phase Elta SLC500/4B-3AC at free air (9266 against 8075 m³/h), so there is no airflow penalty for staying on single phase at this size.
Installation notes
- Mount at any angle, horizontally in a duct run or vertically, but make sure the fan is adequately supported: it weighs 41 kg. AV mounts and mounting feet are available from Elta.
- The flanges are 585mm outside diameter with 12 holes of 12mm on a 560mm 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.
- Wire to diagram 152-502 for 220-240V single phase. Check rotation and airflow direction at first start and that the running current does not exceed the nameplate.
- 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 500mm (061B-0500) (sold each, one per ducted side)
- Elta 149-TC18 transformer speed controller (the controller Elta list for this model)
- Elta APK500/003 ancillary pack (flexible connections, matching flanges, AV mounts and mounting feet in one code; available to order, ask us)

How much air does it move?
Up to 9266 m³/h (2.574 m³/s) at free air, falling to 6336 m³/h at 150 Pa, the highest pressure in Elta's table for this model.
Is the SLC500/4B-1AC single or three phase?
Single phase, 220-240V 50Hz. Peak current is 3.24 A.
Which speed controller does the SLC500/4B-1AC need?
Elta list the 149-TC18 single phase 5 step transformer controller (8 A) for this model. Peak current is 3.24 A, well inside its rating.
How noisy is it?
56 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.
