Elta 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 m h on high speed and still delivering 5486 m h at 100 pa. On low speed it moves 5836 m 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 m 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 m h it gives about 6 air changes an hour in a 1200 m 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 m h. If you need more air, the elta spa560 46-3ac mov...
