SPA315 4 1AC Raptor Plate Axial Fan Single Phase AC 315mm

The Elta SPA315/4-1AC is a 315mm Raptor plate mounted axial fan with a 4 pole single phase motor, moving up to 2167 m³/h in free air and working against static pressures up to 50 Pa. It runs at 44 dB(A) at 3m.It runs on a 220-240V AC external rotor motor at 1320 rpm, insulated to Class F with integral thermal overload protection, drawing 110 W and 0.50 A. The Ziehl-Abegg FE2owlet aerofoil impeller has serrated trailing edges and winglets for lower noise, the motor is weatherproofed to IP44 with an IP55 terminal box, and Elta give a 12 month warranty. 1 Phase AC Motor Up to 2167 m³/h Speed Controllable What it is best used forThrough-wall extract or supply on a single phase supply where noise matters, in workshops, changing rooms, small commercial kitchens, classrooms and retail back of house areas. At 2167 m³/h it gives about 6 air changes an hour in a space of roughly 360 m³, for example 15m x 8m with a 3m ceiling.It is a low pressure fan. The datasheet shows airflow only up to 50 Pa, so it is the wrong choice for ducting or heavy louvres; use a cased axial or inline mixed flow fan there. The motor is IP44, so on an exposed external wall fit a wall cowl or louvre shutter. It is not suitable for corrosive or explosive atmospheres.Why choose this over alternativesAgainst the Compact Elta SCP315/4-1AC (2005 m³/h, up to 75 Pa, 120 W, 50 dB(A)), the Raptor moves more air and is quieter, thanks to its Ziehl-Abegg impeller and external rotor motor. The smaller Elta SPA250/4-1AC (983 m³/h, up to 50 Pa, 46 W, 37 dB(A)) and larger Elta SPA350/4-1AC (2772 m³/h, up to 50 Pa, 120 W, 40 dB(A)) bracket it in the range.Installation notes Mount the 430 x 430mm fan plate securely at any angle using the four 9mm holes on 380mm centres. Make sure the structure can carry its 7 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 152-177 and make all earth connections. Speed can be controlled with the 149-EL31 electronic controller or the 149-TC12 five step transformer controller. 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-EL31 electronic speed controller (3 amp) for variable speed.
