SDA630 68 3AC Raptor Case Mounted Axial Fan Three Phase AC 630mm

The Elta SDA630/68-3AC is a 630mm Raptor SDA short cased axial fan for fitting in 630mm ductwork. It moves up to 10800 m³/h in free air, 9457 m³/h at 50 Pa and still 8158 m³/h at 100 Pa, the highest pressure in Elta's published table for this model. On low speed (star) it moves 8928 m³/h for quieter running.The 6/8 pole three phase AC external rotor motor (380-415V 50Hz) runs at 906 rpm in delta and 736 rpm in star, drawing 620 W and 1.2 A on high speed. It is insulated to Class F with integral thermal overload protection. 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 AC Motor Up to 10800 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 9457 m³/h, roughly 6 air changes an hour in a space of about 1580 m³.Above 100 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. It needs a 380 to 415V three phase supply.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 three phase version has two built in speeds from star/delta switching and draws only 1.2 A per phase on high speed. In the same size there is also the Elta SDA630/6-1AC (6 pole single phase, 10746 m³/h, 49 dB(A)), the Elta SDA630/4-1EC (single phase EC, 12233 m³/h, 53 dB(A)) and the Elta SDA630/4-3EC (three phase EC, 13774 m³/h, 56 dB(A)).If the fan will sit in a wall or panel rather than in a duct, the Elta SPA630/68-3AC 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 152-108: delta connection gives high speed, star gives low speed, and a star/delta switch can select between them. Swap any two supply phases to reverse rotation. For variable speed Elta pair it with the 149-TC33 three phase transformer controller. Wire the thermal contacts (TB TB) into the starter or controller circuit so the motor is protected. 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.
