SDA630 4 3EC Raptor Case Mounted Axial Fan Three Phase EC 630mm

The Elta SDA630/4-3EC is a 630mm Raptor SDA short cased axial fan for fitting in 630mm ductwork. It moves up to 13774 m³/h in free air, 12053 m³/h at 100 Pa and still 9727 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 1208 rpm and draws 1087 W at best efficiency (1.94 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 13774 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 12920 m³/h, roughly 6 air changes an hour in a space of about 2150 m³.It still gives 9727 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 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 48.5% 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 SDA630/4-1EC (single phase EC, 12233 m³/h, 53 dB(A)).For a smaller duct the Elta SDA500/4-3EC gives 9536 m³/h. If the fan will sit in a wall or panel rather than in a duct, the Elta SPA630/4-3EC 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 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-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 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 SDA630/4-3EC Type Cased axial fan, short case Diameter 630mm Max airflow 13774 m³/h Static pressure 200 Pa Motor Three phase EC, 380-480V 50/60Hz, 1208 rpm Power 1087 W (1.94 A peak) Noise 56 dB(A) inlet, 55 dB(A) outlet at 3m IP rating IP54 motor, IP55 terminal box Warranty 1 Year Manufacturer Airflow at 50 Pa 12920 m³/h Airflow at 100 Pa 12053 m³/h Airflow at 150 Pa 11063 m³/h Airflow at 5V control signal 6628 m³/h, 43 dB(A) at 3m Speed control Integrated variable speed drive, 0-10V or potentiometer Overall efficiency 48.5% at best efficiency point FMEG 55 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-MOEA03K3 Manuals & Guides Elta Raptor SDA Datasheet Elta Raptor SDA Installation Manual
