SPA450 4 1AC Raptor Plate Axial Fan Single Phase AC 450mm

The Elta SPA450/4-1AC is a 450mm Raptor plate mounted axial fan with a 4 pole single phase motor, moving up to 7132 m³/h in free air and working against static pressures up to 100 Pa. It runs at 49 dB(A) at 3m.It runs on a 220-240V AC external rotor motor at 1323 rpm, insulated to Class F with integral thermal overload protection, drawing 545 W and 2.45 A. The Ziehl-Abegg FE2owlet aerofoil impeller has serrated trailing edges and winglets for lower noise, the motor is weatherproofed to IP54 with an IP55 terminal box, and Elta give a 12 month warranty. 1 Phase AC Motor Up to 7132 m³/h Speed Controllable What it is best used forThrough-wall extract or supply on a single phase supply where noise matters, in factory units, workshops, warehouses, sports halls and large commercial kitchens where air is moved straight through a wall or bulkhead. At 7132 m³/h it gives about 6 air changes an hour in a space of roughly 1200 m³, for example 25m x 12m 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 ducting or heavy louvres; use a cased axial or inline mixed flow fan there. It is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesAgainst the Compact Elta SCP450/4-1AC (5231 m³/h, up to 100 Pa, 335 W, 51 dB(A)), the Raptor moves more air and is quieter, thanks to its Ziehl-Abegg impeller and external rotor motor. The slower 6 pole Elta SPA450/6-1AC is quieter and cheaper to run (4831 m³/h, up to 50 Pa, 189 W, 41 dB(A)) if you can accept less air. For 0-10V control choose the EC Elta SPA450/4-1EC (5162 m³/h, up to 100 Pa, 300 W, 54 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 16 kg and leave access for maintenance. The motor is prewired to an IP55 terminal box on a flying lead, so the box can be placed to suit the incoming supply. Wire to Elta diagram 152-104B and make all earth connections. Speed can be controlled with the 149-EL61TK electronic controller or the 149-TC18 five step transformer controller. Wire the thermal contacts into the controller circuit as shown on the diagram. Fit a local means of isolation. The AC motor has an auto-reset thermal cut-out, so isolate the supply before any work because the fan can restart on its own once it cools. At first start check impeller rotation and 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-EL61TK electronic speed controller (6 amp) for variable speed. Elta 149-TC18 five step transformer controller (8 amp) as an alternative.
