Summary
See more specification See less specification
The Elta SDA500/4-3EC is a 500mm Raptor SDA short cased axial fan for fitting in 500mm ductwork. It moves up to 9536 m³/h in free air, 8348 m³/h at 100 Pa and still 6019 m³/h at 200 Pa, the highest pressure in Elta's published table for this model.
A three phase EC external rotor motor (380-480V 50/60Hz) with an integrated variable speed drive runs at up to 1555 rpm and draws 920 W at best efficiency (1.53 A peak), with internal electronic overload protection. Speed is set by a 0-10V signal or Elta's 149-POT-10-MI potentiometer. The Ziehl-Abegg FE2owlet aerofoil impeller has serrated trailing edges and winglets for lower noise, the mild steel case is powder coated in RAL 7045 with an IP55 terminal box, the motor is IP54, and Elta give a 12 month warranty.
- 3 Phase
- EC Motor
- Up to 9536 m³/h
- Speed Controllable
What it is best used for
Larger ducted duties on 500mm duct: sports halls, factory bays, warehousing, retail parks and commercial kitchens. At 50 Pa it moves 9065 m³/h, roughly 6 air changes an hour in a space of about 1510 m³.
It still gives 6019 m³/h at 200 Pa, but Elta publish no figures for it beyond that, so very high resistance systems need a mixed flow or centrifugal fan. It is not suitable for corrosive or explosive atmospheres, and the air must stay between -20°C and +70°C.
Why choose this over alternatives
There are 5 Raptor SDA models in the 500mm case, and the choice comes down to supply, noise and control. This EC version gives fully variable speed from a 0-10V signal with no separate controller needed for BMS control, and at 41.8% overall efficiency it is more efficient than any AC model in this size (the best is the SDA500/46-3AC at 34.2%). In the same size there is also the Elta SDA500/4-1AC (4 pole single phase, 8626 m³/h, 51 dB(A)), the Elta SDA500/6-1AC (6 pole single phase, 6188 m³/h, 46 dB(A)), the Elta SDA500/46-3AC (two speed three phase, 8813 m³/h, 53 dB(A)) and the Elta SDA500/4-1EC (single phase EC, 8582 m³/h, 57 dB(A)).
If you need more air, the Elta SDA630/4-3EC moves 13774 m³/h in free air. If the fan will sit in a wall or panel rather than in a duct, the Elta SPA500/4-3EC plate fan uses the same Raptor impeller and motor family on a square mounting plate.
Installation notes
- Fit it in the duct run at any angle, securely supported, with access for maintenance. The case is 250mm long with 12 holes of 10mm on a 541mm PCD at each end for Elta matching flanges 061A-0500-C, and mounting feet 060A-0500-C are available.
- Wire to Elta diagram 152-MOEA03K3 through the fitted terminal box (21mm cable entry). For variable speed connect a 0-10V signal or the 149-POT-10-MI potentiometer to the 10V, E1 and GND terminals.
- Disconnect the fan before any insulation resistance testing. Elta warn this can damage the EC electronics and is not covered by warranty.
- Fit a local means of isolation, and site the discharge so exhaust cannot be drawn back into a room through the open flue of a gas or fuel burning appliance.
- At first start check rotation, airflow direction and that the running current is within the rating plate. Inspect and clean the blades and guards at least every 12 months.
You'll also need
- Elta EC electronic controller 149-POT-10-MI (the potentiometer controller Elta list for every EC Raptor SDA)
- Elta ancillary pack APK500SCD/002 (flexible connections, matching flanges, anti-vibration mounts and mounting feet) available to order, ask us

How much air does the Elta SDA500/4-3EC move?
Up to 9536 m³/h in free air, 9065 m³/h at 50 Pa, 8348 m³/h at 100 Pa and 6019 m³/h at 200 Pa.
What size duct does the SDA500/4-3EC fit?
500mm. The case has a 503mm internal diameter and 12 flange holes of 10mm on a 541mm PCD at each end, which match Elta's 061A-0500-C matching flanges.
How do I control the speed?
The motor has a built in variable speed drive. Use Elta's 149-POT-10-MI potentiometer, which we stock, or a 0-10V signal from a BMS. At a 5V signal it still moves 4435 m³/h at 43 dB(A).
How noisy is it?
Elta quote 59 dB(A) at the inlet and 58 dB(A) at the outlet at 3m at full speed. Matching 1D and 2D flanged silencers (068-0500) are available to order if you need it quieter.
What power supply does it need?
A three phase 380-480V 50/60Hz supply. Peak current is 1.53 A at 400V, and Elta wiring diagram 152-MOEA03K3 applies. It must be wired by a qualified electrician with a local isolator.
Can it be mounted vertically or outside the building?
It can be mounted at any angle, horizontal or vertical. The motor is IP54 with an IP55 terminal box and the fan handles air from -20°C to +70°C, but it is designed to sit in ductwork rather than be exposed to the weather; on an external wall fit a weather cowl such as Elta SWC45/50.
