SCP350 1EC Compact Plate Axial Fan Single Phase EC 350mm

The Elta SCP350-1EC is a 350mm Compact SCP plate mounted axial fan with a single phase EC motor, moving up to 2722 m³/h at full speed and working against static pressures up to 100 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 1780 rpm at 10V, drawing 177 W and 1.54 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 2722 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 workshops, changing rooms, small commercial kitchens, classrooms and retail back of house areas. At 2722 m³/h it gives about 6 air changes an hour in a space of roughly 459 m³, for example 17m x 9m with a 3m ceiling. Turned down to 8V it still moves 2138 m³/h at 49 dB(A).Its pressure (up to 100 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 SCP350/4-1AC (2444 m³/h, up to 75 Pa, 120 W, 50 dB(A)), this EC version needs no separate transformer controller and gives stepless control from a BMS signal. The three phase Elta SCP350/4-3AC gives 2218 m³/h, up to 100 Pa, 120 W, 50 dB(A). Elta's Raptor Elta SPA350/4-1EC is the other single phase EC plate fan at this size (4489 m³/h, up to 100 Pa, 429 W, 57 dB(A)). At reduced speed EC power falls sharply, which is where it saves running cost over a fixed speed AC fan.Installation notes Mount the 485 x 485mm fan plate securely at any angle using the four 10mm holes on 435mm centres, and leave access for maintenance. Supply is 220-277V single phase 50/60Hz. Wire to Elta diagram 152-711. The fitted 149-CD-POT commissioning trimmer sets the maximum speed; remove its jumper when using an external 149-POT-10-MI potentiometer, 2-10V, 4-20mA or PWM signal. Keep control cables within Elta's limits: 10m for a voltage or PWM signal, 300m for 4-20mA. Allow at least 5 minutes between starts from the mains supply, and do not use the isolator for day to day control. High voltage can remain in the motor for up to 10 minutes after isolation. At first start check rotation and airflow direction. Inspect and clean blades and guards at least every 12 months. You'll also need Elta EC electronic controller 149-POT-10-MI for manual speed control.
