SDA500 4 1AC Raptor Case Mounted Axial Fan Single Phase AC 500mm

The Elta SDA500/4-1AC is a 500mm Raptor SDA short cased axial fan for fitting in 500mm ductwork. It moves up to 8626 m³/h in free air, 6354 m³/h at 100 Pa and still 4468 m³/h at 150 Pa, the highest pressure in Elta's published table for this model.A 4 pole single phase AC external rotor motor (220-240V 50Hz) runs at 1250 rpm and draws 719 W at best efficiency (3.18 A peak). It is insulated to Class F with integral thermal overload protection and suits speed control. 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 AC Motor Up to 8626 m³/h Speed Controllable What it is best used forLarger ducted duties on 500mm duct: sports halls, factory bays, warehousing, retail parks and commercial kitchens. At 50 Pa it moves 7474 m³/h, roughly 6 air changes an hour in a space of about 1250 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 5 Raptor SDA models in the 500mm case, and the choice comes down to supply, noise and control. This 4 pole single phase version runs from a standard 230V supply at 1250 rpm. In the same size there is also the Elta SDA500/6-1AC (6 pole single phase, 6188 m³/h, 46 dB(A)), the Elta SDA500/46-3AC (two speed three phase, 8813 m³/h, 53 dB(A)), the Elta SDA500/4-1EC (single phase EC, 8582 m³/h, 57 dB(A)) and the Elta SDA500/4-3EC (three phase EC, 9536 m³/h, 59 dB(A)).If you need more air, the Elta SDA560/4-1AC moves 11678 m³/h in free air. For a smaller duct the Elta SDA450/4-1AC gives 6674 m³/h. If the fan will sit in a wall or panel rather than in a duct, the Elta SPA500/4-1AC 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 12 holes of 10mm on a 541mm PCD at each end for Elta matching flanges 061A-0500-C, and mounting feet 060A-0500-C are available. Wire to Elta diagram 152-104B through the fitted IP55 terminal box (21mm cable entry), and connect the thermal cut-out leads (TB TB) into the control circuit so the motor is protected. For speed control Elta list the 149-EL61TK or 149-TC18 for this model; check the controller amp rating against the 3.18 A peak current. 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.
