SCP450 4 1AC Compact Plate Axial Fan Single Phase AC 450mm

The Elta SCP450/4-1AC is a 450mm Compact SCP plate mounted axial fan with a single phase 4 pole AC motor, moving up to 5231 m³/h in free air and working against static pressures up to 100 Pa. It is built for moving large volumes of air against low resistance, straight through a wall, panel or bulkhead.The 220-240V induction motor runs at 1365 rpm with greased for life ball bearings, drawing 335 W and 1.62 A. The Series 1 impeller has adjustable pitch GRP aerofoil blades, the mild steel plate and motor are powder coated and the guards epoxy coated, an IP55 terminal box is fitted on 550mm of flexible conduit, and Elta give a 12 month warranty. 1 Phase AC Motor Up to 5231 m³/h Speed Controllable What it is best used forThrough-wall extract or supply on a single phase supply in workshops, school halls, commercial kitchens with little or no ducting, vehicle garages and small industrial units. At 5231 m³/h it gives about 6 air changes an hour in a space of roughly 880 m³, for example 22m x 10m 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 ducted systems or heavy louvres; use a cased axial or inline mixed flow fan there. When speed controlled Elta limit the air temperature to +50°C (+70°C at fixed speed), and it is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesIf you have a three phase supply, the Elta SCP450/4-3AC is the same size (6138 m³/h, up to 100 Pa, 373 W, 53 dB(A)). The single phase Elta SCP450-1EC uses an EC motor with built in speed control and gives 7337 m³/h, up to 200 Pa, 424 W, 60 dB(A), so it suits sites that need more pressure or BMS control. Elta's Raptor Elta SPA450/4-1AC is the alternative 450mm single phase plate fan with a Ziehl-Abegg impeller (7132 m³/h, up to 100 Pa, 545 W, 49 dB(A)).Installation notes Mount the 575 x 575mm fan plate securely at any angle using the four 10mm holes on 535mm centres. Make sure the structure can carry its 14 kg and leave access for maintenance. The motor is prewired to an IP55 terminal box on 550mm of 20mm flexible conduit. Wire to Elta diagram 152-500 and make all earth connections; the thermal cut-out must be wired into the starter or controller control circuit. For speed control Elta list the 149-TC14 five step transformer controller (4 A). Diagram 152-500 also shows connection to the 149-EL31TK and 149-EL61TK electronic controllers; choose one rated above the motor current. Fit a local means of isolation, but do not use the isolator for day to day on and off control. Elta warn this shortens motor life; use a controller or switch instead. At first start check rotation, airflow direction and that the running current does not exceed the rating plate. Inspect and clean blades and guards at least every 12 months. You'll also need Elta 149-TC14 five step transformer controller (4 amp) for speed control.
