Elta Spa250 4-1ac Raptor Plate Axial Fan Single Phase Ac - 250mm

The elta spa250 4-1ac is a 250mm raptor plate mounted axial fan with a 4 pole single phase motor, moving up to 983 m h in free air and working against static pressures up to 50 pa. It runs at 37 db a at 3m.It runs on a 220-240v ac external rotor motor at 1368 rpm, insulated to class f with integral thermal overload protection, drawing 46 w and 0.24 A. The ziehl-abegg fe2owlet aerofoil impeller has serrated trailing edges and winglets for lower noise, the motor is weatherproofed to ip44 with an ip55 terminal box, and elta give a 12 month warranty. 1 Phase ac motor up to 983 m h speed controllable what it is best used forthrough-wall extract or supply on a single phase supply where noise matters, in plant rooms, stores, small workshops, garages and back of house rooms in shops. At 983 m h it gives about 6 air changes an hour in a space of roughly 165 m , for example 11m x 5m with a 3m ceiling.It is a low pressure fan. The datasheet shows airflow only up to 50 pa, so it is the wrong choice for ducting or heavy louvres use a cased axial or inline mixed flow fan there. The motor is ip44, so on an exposed external wall fit a wall cowl or louvre shutter. It is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesagainst the compact elta scp250 4-1ac 954 m h, up to 50 pa, 80 w, 42 db a , the raptor moves more air and is quieter, thanks to its ziehl-abegg impeller and external rotor motor.
