Summary

The Elta Multiflow SMB650/4-1AC is a 650mm square inline mixed flow box fan with a single phase AC motor, moving up to 7974 m³/h in free air and 6786 m³/h against 200 Pa. It fits straight into 650mm ductwork on Ductmate flanges at each end.

The 4 pole motor runs at 1380 rpm on a 220 to 240V 50Hz supply, absorbing 1.143 kW with a peak current of 5.28 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 7974 m³/h
  • Speed Controllable

What it is best used for

The largest single phase SMB, for high volume extract and supply on 650mm ductwork: large commercial kitchen canopies, restaurants, warehouses, factory units, sports halls and plant rooms. It holds 7445 m³/h at 100 Pa, 6786 m³/h at 200 Pa and still 4381 m³/h at 400 Pa.

At 1.143 kW and up to 5.28 A it needs a dedicated circuit and the 16 A transformer controller for speed control. Where three phase is available, the SMB650/4-3AC gives more air for a much lower running current.

Why choose this over alternatives

Against the three phase SMB650/4-3AC, this single phase model moves less air (7974 against 10480 m³/h in free air) and draws 5.28 A on 230V against 2.89 A per phase. Choose it where a three phase supply is not available.

Within the single phase range, it sits above the SMB550/4-1AC (5314 m³/h free air), and is the largest single phase SMB Elta make.

Installation notes

  • Mount the fan at any angle in the duct run, securely supported, and leave access for maintenance. It weighs 47 kg.
  • Connect with the 650mm Ductmate flanges at each end. Elta's flexible connectors (063-0650-MFB) and anti vibration mounts (062-003) 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-TC116 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 650mm flexible connectors 063-0650-MFB (each), available to order, ask us.
