SPA400 4 1AC Raptor Plate Axial Fan Single Phase AC 400mm

The Elta SPA400/4-1AC is a 400mm Raptor plate mounted axial fan with a 4 pole single phase motor, moving up to 3935 m³/h in free air and working against static pressures up to 100 Pa. It runs at 48 dB(A) at 3m.It runs on a 220-240V AC external rotor motor at 1372 rpm, insulated to Class F with integral thermal overload protection, drawing 240 W. 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 3935 m³/h Speed Controllable What it is best used forThrough-wall extract or supply on a single phase supply where noise matters, in workshops, school halls, commercial kitchens with little or no ducting, vehicle garages and small industrial units. At 3935 m³/h it gives about 6 air changes an hour in a space of roughly 648 m³, for example 18m x 9m 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 SCP400/4-1AC (2578 m³/h, up to 100 Pa, 121 W, 50 dB(A)), the Raptor moves more air and is quieter, thanks to its Ziehl-Abegg impeller and external rotor motor. On a three phase site the Elta SPA400/46-3AC gives similar air (3856 m³/h, up to 100 Pa, 227 W, 48 dB(A) on high speed) with a star/delta low speed. For 0-10V control choose the EC Elta SPA400/4-1EC (5299 m³/h, up to 200 Pa, 490 W, 58 dB(A)).Installation notes Mount the 540 x 540mm fan plate securely at any angle using the four 10mm holes on 490mm centres. Make sure the structure can carry its 10 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-EL31TK electronic controller or the 149-TC14 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-EL31TK electronic speed controller (3 amp) for variable speed. Elta 149-TC14 five step transformer controller (4 amp) as an alternative.
