SCP315 4 3AC Compact Plate Axial Fan Three Phase AC 315mm

The Elta SCP315/4-3AC is a 315mm Compact SCP plate mounted axial fan with a three phase 4 pole AC motor, moving up to 1854 m³/h in free air and working against static pressures up to 75 Pa. It is built for moving large volumes of air against low resistance through a wall, panel or bulkhead.The 380-415V induction motor runs at 1445 rpm with greased for life ball bearings, drawing 120 W and 0.34 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. 3 Phase AC Motor Up to 1854 m³/h Speed Controllable What it is best used forThrough-wall extract or supply on three phase sites in workshops, changing rooms, small commercial kitchens, classrooms and retail back of house areas. At 1854 m³/h it gives about 6 air changes an hour in a space of roughly 315 m³, for example 15m x 7m with a 3m ceiling.It is a low pressure fan. The datasheet shows airflow only up to 75 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 alternativesThe single phase Elta SCP315/4-1AC is the same size (2005 m³/h, up to 75 Pa, 120 W, 50 dB(A)), for sites without three phase. For built in speed control without an inverter, the Elta SCP315-1EC gives 1854 m³/h, up to 100 Pa, 110 W, 52 dB(A).Installation notes Mount the 430 x 430mm fan plate securely at any angle using the four 10mm holes on 380mm centres. Make sure the structure can carry its 7 kg and leave access for maintenance. Wire to Elta diagram 152-611 through the IP55 terminal box on 550mm of 20mm flexible conduit. The thermal cut-out must be wired into the starter control circuit. For variable speed Elta list the 149-TC33 five step transformer controller or an Eltadrive inverter (149-ODE3-14075-3KA1B 3 phase to 3 phase, or 149-ODE3-12037-1KB1B from a single phase supply). Fuses and circuit breakers only give short circuit protection, so Elta advise a starter with overload protection. Do not use the isolator for day to day on and off control, as it shortens motor life. At first start check rotation (swap any two supply phases to reverse it) and that the running current does not exceed the rating plate. Inspect and clean blades and guards at least every 12 months.
