Elta Spa500 4-1ac Raptor Plate Axial Fan Single Phase Ac - 500mm

The elta spa500 4-1ac is a 500mm raptor plate mounted axial fan with a 4 pole single phase motor, moving up to 8514 m h in free air and working against static pressures up to 150 pa. It runs at 51 db a at 3m.It runs on a 220-240v ac external rotor motor at 1210 rpm, insulated to class f with integral thermal overload protection, drawing 750 w and 3.46 A. 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. 1 Phase ac motor up to 8514 m h speed controllable what it is best used forthrough-wall extract or supply on a single phase supply where noise matters, in factory units, workshops, warehouses, sports halls and large commercial kitchens where air is moved straight through a wall or bulkhead. At 8514 m h it gives about 6 air changes an hour in a space of roughly 1404 m , for example 27m x 13m with a 4m ceiling.With airflow shown up to 150 pa it copes with a louvre shutter, cowl or short duct, but for long ducted runs use a cased axial or inline mixed flow fan. It is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesagainst the compact elta scp500 4-1ac 6772 m h, up to 100 pa, 411 w, 58 db a , the raptor moves more air and is quieter, thanks to its ziehl-abegg impeller and external rotor motor. The slower 6 pole elta spa500 6-1ac is quieter and cheaper to run 6340 m h, up to 75 pa, 289 w, 44 db ...
