SCD400 Cased Axial Fan Three Phase AC 400mm

The Elta SCD400/4-3AC is a 400mm Compact SCD cased axial fan with a short 190mm case, built for moving large volumes of air against low resistance. It moves up to 4993 m³/h at free air and 3690 m³/h against 75 Pa, from a 4 pole three phase AC motor running at 1405 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 4993 m³/h Speed Controllable What it is best used forMoving a lot of air against low resistance on a three phase supply: kitchens, shops, small industrial units and school spaces, mounted in a duct run or on a wall. It moves 4993 m³/h at free air on 0.324 kW, at 51 dB(A) at 3m.Its table stops at 75 Pa (3690 m³/h), so keep duct runs short and avoid filters or attenuators in the line; for more pressure, choose a long cased SLC.Why choose this over alternativesThe single phase Elta SCD400/4-1AC moves 2869 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 SLC400/4-3AC (4968 m³/h, to 100 Pa), the SCD is a much shorter and lighter fan (190mm case, 12 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 SCD450/4-3AC moves 5447 m³/h.Installation notes The fan is short (190mm) and light (12 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 466mm outside diameter with 8 holes of 10mm on a 438mm 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.
