Summary
See more specification See less specification
The Elta SDA350/4-1AC is a 350mm Raptor SDA short cased axial fan for fitting in 350mm ductwork. It moves up to 2570 m³/h in free air and still 1544 m³/h at 50 Pa, the highest pressure in Elta's published table for this model.
A 4 pole single phase AC external rotor motor (220-240V 50Hz) runs at 1075 rpm and draws 119 W at best efficiency (0.54 A peak). It is insulated to Class F with integral thermal overload protection and suits speed control. The Ziehl-Abegg FE2owlet aerofoil impeller has serrated trailing edges and winglets for lower noise, the mild steel case is powder coated in RAL 7045 with an IP55 terminal box, the motor is IP44, and Elta give a 12 month warranty.
- 1 Phase
- AC Motor
- Up to 2570 m³/h
- Speed Controllable
What it is best used for
Ducted extract or supply on 350mm duct for classrooms, small retail units, squash courts and workshops where the run is short and the grilles are generous. At 50 Pa it moves 1544 m³/h, roughly 6 air changes an hour in a space of about 260 m³.
Its published curve stops at 50 Pa, so it is the wrong fan for long duct runs, filters, heater batteries or attenuators; for those a centrifugal box fan or an inline mixed flow fan holds its airflow far better. It is not suitable for corrosive or explosive atmospheres, and the air must stay between -20°C and +70°C.
Why choose this over alternatives
There are 2 Raptor SDA models in the 350mm case, and the choice comes down to supply, noise and control. This 4 pole single phase version runs from a standard 230V supply at 1075 rpm. In the same size there is also the Elta SDA350/4-1EC (single phase EC, 4316 m³/h, 57 dB(A)).
If you need more air, the Elta SDA400/4-1AC moves 3611 m³/h in free air. For a smaller duct the Elta SDA315/4-1AC gives 2185 m³/h. If the fan will sit in a wall or panel rather than in a duct, the Elta SPA350/4-1AC plate fan uses the same Raptor impeller and motor family on a square mounting plate.
Installation notes
- Fit it in the duct run at any angle, securely supported, with access for maintenance. The case is 180mm long with 8 holes of 10mm on a 395mm PCD at each end for Elta matching flanges 061A-0350-C, and mounting feet 060A-0350-C are available.
- Wire to Elta diagram 152-104B through the fitted IP55 terminal box (21mm cable entry), and connect the thermal cut-out leads (TB TB) into the control circuit so the motor is protected.
- For speed control Elta list the 149-TC12 for this model; check the controller amp rating against the 0.54 A peak current.
- Fit a local means of isolation, and site the discharge so exhaust cannot be drawn back into a room through the open flue of a gas or fuel burning appliance.
- At first start check rotation, airflow direction and that the running current is within the rating plate. Inspect and clean the blades and guards at least every 12 months.

How much air does the Elta SDA350/4-1AC move?
Up to 2570 m³/h in free air and 1544 m³/h at 50 Pa.
What size duct does the SDA350/4-1AC fit?
350mm. The case has a 356mm internal diameter and 8 flange holes of 10mm on a 395mm PCD at each end, which match Elta's 061A-0350-C matching flanges.
Which speed controller do I need?
Elta list the 149-TC12 for this fan. The motor draws 0.54 A peak, so check the rating if you put more than one fan on a controller.
How noisy is it?
Elta quote 45 dB(A) at the inlet and 45 dB(A) at the outlet at 3m at full speed. Matching 1D and 2D flanged silencers (068-0350) are available to order if you need it quieter.
What power supply does it need?
A single phase 220-240V 50Hz supply. Peak current is 0.54 A at 230V, and Elta wiring diagram 152-104B applies. It must be wired by a qualified electrician with a local isolator.
Can it be mounted vertically or outside the building?
It can be mounted at any angle, horizontal or vertical. The motor is IP44 with an IP55 terminal box and the fan handles air from -20°C to +70°C, but it is designed to sit in ductwork rather than be exposed to the weather; on an external wall fit a weather cowl such as Elta SWC35/40.
