Summary
See more specification See less specification
The Elta SCD315/4-3AC is a 315mm Compact SCD cased axial fan with a short 180mm case, built for moving large volumes of air against low resistance. It moves up to 2102 m³/h at free air and 1861 m³/h against 25 Pa, from a 4 pole three phase AC motor running at 1440 rpm.
The mild steel casing is powder coated in Telegrey 1 (RAL 7045) with the motor and adjustable pitch aerofoil impeller held within its length, and an IP55 terminal box is fitted as standard. The three phase TENV motor is IP55, multi voltage (star 400V as supplied, or delta 230V three phase) and suits the Eltadrive inverter range or a 149-TC33 transformer controller. It is rated for air from -20°C to +70°C at fixed speed (+50°C with a speed controller) and Elta give a 12 month warranty.
- 3 Phase
- AC Motor
- Up to 2102 m³/h
- Speed Controllable
What it is best used for
Moving a lot of air against low resistance on a three phase supply: small plant rooms, stores, kitchens and shops, mounted in a duct run or on a wall. It moves 2102 m³/h at free air on 0.12 kW, at 50 dB(A) at 3m.
Its table stops at 25 Pa (1861 m³/h), so it is only for very short duct runs or through the wall; for any real duct resistance choose a long cased SLC instead.
Why choose this over alternatives
The single phase Elta SCD315/4-1AC moves 1854 m³/h at the same size. Choose this three phase model where you have a three phase supply and want inverter control, as Elta rate the three phase motor for use with the Eltadrive range.
Against the long cased Elta SLC315/4-3AC (1440 m³/h, to 75 Pa), the SCD is a much shorter and lighter fan (180mm case, 9 kg) with a powder coated finish, and costs less. Choose the SLC for higher pressure, external mounting (it is hot dip galvanised and rated for outdoor use as standard) or heavier industrial duty. Need more air? The Elta SCD350/4-3AC moves 2239 m³/h.
Installation notes
- The fan is short (180mm) and light (9 kg), so it fits in a duct run or on a wall where space is tight. Mounting feet and AV mounts are available from Elta.
- The flanges are 382mm outside diameter with 8 holes of 10mm on a 356mm PCD. Use Elta matching flanges and flexible connectors to join it to ductwork.
- Supplied star (Y) connected for 400V three phase, wiring diagram 152-611, via the fitted IP55 terminal box (21mm cable entry). The motor can be reconnected to delta for 230V three phase from an inverter.
- If you run it on a speed controller, keep the air temperature at or below +50°C (Elta's limit with a controller); at fixed speed it is rated to +70°C.

- Eltadrive 149-ODE3-14075-3KA1B inverter for a three phase supply (or 149-ODE3-12037-1K1B from single phase; available to order, ask us)
