SDA630 4 1EC Raptor Case Mounted Axial Fan Single Phase EC 630mm

The Elta SDA630/4-1EC is a 630mm Raptor SDA short cased axial fan for fitting in 630mm ductwork. It moves up to 12233 m³/h in free air, 9634 m³/h at 100 Pa and still 7682 m³/h at 150 Pa, the highest pressure in Elta's published table for this model.A single phase EC external rotor motor (200-277V 50/60Hz) with an integrated variable speed drive runs at up to 1056 rpm and draws 737 W at best efficiency (3.42 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. 1 Phase EC Motor Up to 12233 m³/h Speed Controllable What it is best used forThe biggest Raptor SDA size, for high volume ducted ventilation on 630mm duct in sports halls, factories, warehousing and large retail units. At 50 Pa it moves 10991 m³/h, roughly 6 air changes an hour in a space of about 1830 m³.Above 150 Pa Elta publish no figures, so for long duct runs with filters, heater batteries or attenuators an inline mixed flow or centrifugal box fan is the safer choice. It is not suitable for corrosive or explosive atmospheres, and the air must stay between -20°C and +70°C.Why choose this over alternativesThere are 4 Raptor SDA models in the 630mm 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 46.3% overall efficiency it is more efficient than any AC model in this size (the best is the SDA630/68-3AC at 33.8%). In the same size there is also the Elta SDA630/6-1AC (6 pole single phase, 10746 m³/h, 49 dB(A)), the Elta SDA630/68-3AC (two speed three phase, 10800 m³/h, 49 dB(A)) and the Elta SDA630/4-3EC (three phase EC, 13774 m³/h, 56 dB(A)).For a smaller duct the Elta SDA500/4-1EC gives 8582 m³/h. If the fan will sit in a wall or panel rather than in a duct, the Elta SPA630/4-1EC 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 16 holes of 12mm on a 674mm PCD at each end for Elta matching flanges 061A-0630-C, and mounting feet 060A-0630-C are available. Wire to Elta diagram 152-MOEA03K1 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 APK630SCD/002 (flexible connections, matching flanges, anti-vibration mounts and mounting feet) available to order, ask us Browse more cased axial fans, axial fans or Elta fans, or call us for help choosing the right fan.Specifications Model SDA630/4-1EC Type Cased axial fan, short case Diameter 630mm Max airflow 12233 m³/h Static pressure 150 Pa Motor Single phase EC, 200-277V 50/60Hz, 1056 rpm Power 737 W (3.42 A peak) Noise 53 dB(A) at 3m IP rating IP54 motor, IP55 terminal box Warranty 1 Year Manufacturer Airflow at 50 Pa 10991 m³/h Airflow at 100 Pa 9634 m³/h Airflow at 5V control signal 5598 m³/h, 41 dB(A) at 3m Speed control Integrated variable speed drive, 0-10V or potentiometer Overall efficiency 46.3% at best efficiency point FMEG 53 Case 250mm long, 634mm internal diameter, 709mm flange diameter Flange fixings 16 holes 12mm on 674mm PCD Impeller Ziehl-Abegg FE2owlet aerofoil with serrated trailing edges Finish Powder coated mild steel, RAL 7045 Operating temperature -20°C to +70°C, up to 95% RH Weight 25 kg Wiring diagram 152-MOEA03K1 Manuals & Guides Elta Raptor SDA Datasheet Elta Raptor SDA Installation Manual
