Elta Spa450 4-1ac Raptor Plate Axial Fan Single Phase Ac - 450mm

The elta spa450 4-1ac is a 450mm raptor plate mounted axial fan with a 4 pole single phase motor, moving up to 7132 m h in free air and working against static pressures up to 100 pa. It runs at 49 db a at 3m.It runs on a 220-240v ac external rotor motor at 1323 rpm, insulated to class f with integral thermal overload protection, drawing 545 w and 2.45 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 7132 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 7132 m h it gives about 6 air changes an hour in a space of roughly 1200 m , for example 25m x 12m with a 4m ceiling.It is a low pressure fan. The datasheet shows airflow only up to 100 pa, so it is the wrong choice for ducting or heavy louvres use a cased axial or inline mixed flow fan there. It is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesagainst the compact elta scp450 4-1ac 5231 m h, up to 100 pa, 335 w, 51 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 spa450 6-1ac is quieter and cheaper to run 4831 m h, u...
