Elta Scp450 1ec Compact Plate Axial Fan Single Phase Ec - 450mm

The elta scp450-1ec is a 450mm compact scp plate mounted axial fan with a single phase ec motor, moving up to 7337 m h at full speed and working against static pressures up to 200 pa. Speed is fully variable, so one fan can be set to the duty you need.The ie5 efficiency ec motor has an integrated variable speed drive, runs on 220-277v 50 60hz and reaches 1800 rpm at 10v, drawing 424 w and 3.99 A. Speed is set by a 2-10v dc signal, 4-20ma, a pwm signal 10-95% or a potentiometer. The series 1 impeller has adjustable pitch grp aerofoil blades, an ip55 terminal box is fitted on trailing leads, and elta give a 12 month warranty. 1 Phase ec motor up to 7337 m h speed controllable what it is best used forthrough-wall ventilation that needs variable or bms controlled speed on a single phase supply in factory units, workshops, warehouses, sports halls and large commercial kitchens where air is moved straight through a wall or bulkhead. At 7337 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. Turned down to 8v it still moves 5609 m h at 53 db a .Its pressure up to 200 pa on the datasheet is high for a plate fan, but it is still not a ducted fan for long runs use a cased axial or inline mixed flow fan there. Ec fans are rated for air up to 60 c, and it is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesagainst the single phase ac elta scp450 4-1ac 5231 m h, up to 100 pa, 335 w, 51 db...
