Summary
See more specification See less specification
The Elta Multiflow SMB500/4-1AC is a 500mm square inline mixed flow box fan with a single phase AC motor, moving up to 3856 m³/h in free air and 2646 m³/h against 200 Pa. It fits straight into 500mm ductwork on Ductmate flanges at each end.
The 4 pole motor runs at 1385 rpm on a 220 to 240V 50Hz supply, absorbing 0.386 kW with a peak current of 1.99 A, and has sealed for life bearings. The casing is stiffened pre-galvanised sheet steel, the impeller has 7 backward curved aerofoil blades in high performance composite, and it handles air up to 60°C. Elta give a 12 month warranty.
- 1 Phase
- AC Motor
- Up to 3856 m³/h
- Speed Controllable
What it is best used for
Medium commercial extract and supply on a single phase supply where the ductwork is 500mm: restaurant and kitchen canopy extract with grease filters, plant and lift motor rooms, warehouse and workshop ventilation. It holds 3388 m³/h at 100 Pa and 2646 m³/h at 200 Pa.
It runs out of pressure above 250 Pa (486 m³/h at 300 Pa). For higher resistance or more air, the SMB550 or SMB650 is the better choice.
Why choose this over alternatives
Against the three phase SMB500/4-3AC, this single phase model moves almost the same air in free air (3856 against 3888 m³/h) and draws 1.99 A on 230V against 0.88 A per phase. It is the straightforward choice where only a single phase supply is available.
The SMB450/4-1AC has almost identical performance with a 450mm connection, so pick between the two on duct size. For more air, the SMB550/4-1AC moves 5314 m³/h.
Installation notes
- Mount the fan at any angle in the duct run, securely supported, and leave access for maintenance. It weighs 27 kg.
- Connect with the 500mm Ductmate flanges at each end. Elta's flexible connectors (063-0500-MFB) and anti vibration mounts (062-002) reduce transmitted noise and vibration.
- Wire to Elta diagram 152-104A on a 230V single phase supply. The thermal cut out terminals (TB) must be connected into the control circuit, and Elta specify the 149-TC14 transformer controller for speed control.
- Fit a means of isolation and earth the fan. Fuses and breakers only give short circuit protection, so Elta advise a starter with overload protection for the motor. Check rotation, airflow direction and running current on first start.
- Not for corrosive or explosive atmospheres. Locate the discharge away from open flues, and inspect and clean the impeller and motor at least every 12 months.
You'll also need
- Elta 149-TC14 single phase 5 step transformer controller (4 A), the controller Elta specify for this fan.

- Elta 500mm flexible connectors 063-0500-MFB (each), available to order, ask us.
