Summary
See more specification See less specification
The Elta SB630-CYL4-3 is a 630mm Biflow SB bifurcated cylindrical axial fan. The motor sits in a tunnel outside the airstream, so the fan can move air at up to +200°C, or air carrying grease or dust, without that air passing over the motor. It moves up to 16204 m³/h in free air, 14540 m³/h at 100 Pa and 12391 m³/h at 200 Pa, the highest pressure in Elta's published table for this model.
A 4 pole three phase AC motor (380-415V 50Hz) runs at 1410 rpm with a 2.2 kW output and 4.43 A peak current. It is a foot mounted, totally enclosed IP55 motor with Class H insulation and sealed for life bearings. The adjustable pitch aerofoil impeller has pressure die cast aluminium blades, the steel casing is hot dip galvanised after fabrication and suitable for external mounting, and Elta give a 12 month warranty.
- 3 Phase
- AC Motor
- Up to 16204 m³/h
- Speed Controllable
What it is best used for
High volume hot or contaminated extract on 630mm duct: large commercial kitchen canopies, boiler houses, spray booths, foundry or heavy industrial process extract, and hot gas duties up to +200°C. At 100 Pa it moves 14540 m³/h.
It is not rated for explosive atmospheres, so it is the wrong fan for ATEX zones, and Elta's manual also excludes corrosive atmospheres, so talk to us before using it on aggressive fumes. The motor must sit in ambient air between -20°C and +54°C even when the airstream is much hotter.
Why choose this over alternatives
Running four pole at 1410 rpm keeps the noise to 70 dB(A) at the inlet for a fan moving 16204 m³/h, and it still gives 12391 m³/h at 200 Pa. If around half the air will do, the Elta SB500-CYL4-3 moves 8280 m³/h at 62 dB(A) in a lighter 47 kg casing.
A bifurcated fan costs more than a standard cased axial because the motor has its own tunnel and Class H insulation. If the air is clean and below +70°C, a standard cased axial fan does the job for less money; choose the Biflow when heat, grease or dust would shorten a normal motor's life. The cylindrical case has a single entry motor tunnel, and at this size it is the only Biflow SB option.
Installation notes
- Mount it at any angle, adequately supported, with access for maintenance. Do not obstruct the motor tunnel, as the motor relies on ambient air through it for cooling.
- This cylindrical model has a single entry motor tunnel, which must face vertically upwards or horizontally to keep the motor cool.
- The case is 570mm long with 12 holes of 12mm on a 690mm PCD at each end, matching Elta 061B-0630 flanges. Use Elta's high temperature 063-0630-PU250 flexible connectors for hot air duties.
- Wire to Elta diagram 152-616. Fuses and breakers give short circuit protection only, so fit a starter with overload protection; for variable speed Elta show the fan run from an inverter.
- Fit a local means of isolation, check rotation and airflow direction at first start, and inspect and clean the impeller at least every 12 months.
You'll also need
- Elta matching flanges 630mm (061B-0630, the flanges Elta list for the Biflow SB)
- Elta ancillary pack APK630SBCYL/003 (flexible connections, matching flanges, anti-vibration mounts and mounting feet) available to order, ask us
- Elta bell mouth inlet 241B-0630-BELL and impeller side guard 078C-0630-C available to order, ask us

How much air does the Elta SB630-CYL4-3 move?
Up to 16204 m³/h in free air, 14540 m³/h at 100 Pa and 12391 m³/h at 200 Pa.
What temperature air can it handle?
Up to +200°C in the airstream, because the motor sits in its own tunnel outside the airflow. The motor itself needs ambient air between -20°C and +54°C.
Is it suitable for commercial kitchen extract?
Yes. Elta list kitchen extract as a typical application, and keeping the motor out of the greasy airstream is the main reason to choose a bifurcated fan. Clean the impeller regularly as part of the kitchen's duct cleaning regime.
Can I control the speed?
Yes, with an inverter. Elta's wiring diagram 152-616 shows the fan run from a three phase inverter, or from a single to three phase inverter with the motor reconnected in delta. Ask us to confirm the right one.
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, as long as the motor tunnel is not obstructed. On this cylindrical model the tunnel opening must face up or sideways.
What duct size does it fit?
630mm. The case has a 630mm internal diameter with 12 flange holes of 12mm on a 690mm PCD, and Elta's 061B-0630 matching flanges fit it.
