SPA450 46 3AC Raptor Plate Axial Fan Three Phase AC 450mm

The Elta SPA450/46-3AC is a 450mm Raptor plate mounted axial fan with a two speed three phase motor, moving up to 7193 m³/h on high speed and still delivering 5486 m³/h at 100 Pa. On low speed it moves 5836 m³/h for quieter running.The 380-415V AC external rotor motor runs at 1354 rpm in delta and 1016 rpm in star, insulated to Class F with integral thermal overload protection, drawing 538 W and 1.08 A on high speed. The Ziehl-Abegg FE2owlet aerofoil impeller has serrated trailing edges and winglets for lower noise, the motor is weatherproofed to IP54 with an IP55 terminal box, and Elta give a 12 month warranty. 3 Phase AC Motor Up to 7193 m³/h Speed Controllable What it is best used forWall and roof extract in larger spaces with a three phase supply: sports halls, warehouses, factory bays, industrial units, retail parks and school halls. At 7193 m³/h it gives about 6 air changes an hour in a 1200 m³ space, for example 20m x 15m with a 4m ceiling.It is a plate fan for low resistance installations, so for ducted runs a cased axial or inline mixed flow fan is the better fit. It is not suitable for corrosive or explosive atmospheres, and a single phase supply needs the SPA450/4-1AC instead.Why choose this over alternativesThe Elta SPA450/4-1AC moves about the same air on single phase, but draws 2.45 A against 1.08 A per phase here and has no built in second speed. The Elta SPA450/6-1AC is quieter at 41 dB(A) but tops out at 4831 m³/h. If you need more air, the Elta SPA560/46-3AC moves 11336 m³/h on high speed.Installation notes Mount the fan plate securely at any angle, in a wall, panel or bulkhead, using the four corner fixing holes, and leave access for future maintenance. Wire to Elta diagram 152-108. Delta connection gives high speed, star gives low speed, and a star/delta switch can be fitted to select between them. Swap any two supply phases to reverse rotation. For variable speed, Elta pair this fan with the 149-TC33 three phase transformer controller wired through its own terminal box. The thermal contacts (TB TB) must be wired into the starter or controller circuit so the motor is protected. Fit a local means of isolation. At first start check rotation, airflow direction and that the running current does not exceed the rating plate. Inspect and clean blades and guards at least every 12 months.
