Elta SCP710/1EC Compact Plate Axial Fan Single Phase EC - 710mm

The Elta SCP710-1EC is a 710mm Compact SCP plate mounted axial fan with a single phase EC motor, moving up to 17273 m³/h at full speed and working against static pressures up to 400 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 1555 rpm at 10V, drawing 1.36 kW and 9.98 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 17273 m³/h Speed Controllable What it is best used forThrough-wall ventilation that needs variable or BMS controlled speed on a single phase supply in warehouses, distribution sheds, factories, sports halls and large industrial units, often as a bank of fans along one wall. At 17273 m³/h it gives about 6 air changes an hour in a space of roughly 2888 m³, for example 38m x 19m with a 4m ceiling. Turned down to 8V it still moves 12992 m³/h at 66 dB(A).Its pressure (up to 400 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 three phase Elta SCP710/4/6-3AC (17921 m³/h, up to 200 Pa, 1.58 kW, 62 dB(A)), it runs on single phase and reaches far higher pressure, though it is louder at full speed. The Raptor Elta SPA710/6-1EC is quieter (13104 m³/h, up to 150 Pa, 659 W, 51 dB(A)) where pressure is low. At reduced speed EC power falls sharply, which is where it saves running cost over a fixed speed AC fan.Installation notes Mount the 850 x 850mm fan plate securely at any angle using the four 10mm holes on 810mm centres, and leave access for maintenance. Supply is 220-277V single phase 50/60H
