Summary
See more specification See less specification
The Elta SSDL125-1EC-RT is a 125mm Singleflow SSDL centrifugal box fan with rectangular inlet and outlet spigots and a pre-fitted terminal box. It moves up to 601 m³/h in free air, 493 m³/h at 200 Pa and still 302 m³/h at 500 Pa, the highest pressure in Elta's published table.
A single phase EC external rotor motor (220-240V 50/60Hz) drives a backward curved impeller balanced to ISO1940-1, at up to 3555 rpm with an integrated commissioning control for setting speed. The 1.2mm galvanised steel casing is acoustically lined and suitable for external mounting, the IP44 motor has sealed for life bearings and runs in air from -20°C to +60°C, and Elta backs it with a 12 month warranty.
- 1 Phase
- EC Motor
- Up to 601 m³/h
- Speed Controllable
What it is best used for
Extract from washrooms, changing rooms, small kitchenettes and single offices on 125mm duct, especially in schools, hotels and offices where the fan needs to sit in a plant space, ceiling void or on a roof. At 100 Pa it moves 547 m³/h, roughly 10 air changes an hour in a room of about 55 m³.
If the duct is short and the space is indoors, a simple inline fan may do the job for less money. It is not suitable for corrosive or explosive atmospheres, and the airstream must stay within -20°C to +60°C.
Why choose this over alternatives
This is the 125mm SSDL with rectangular spigots and terminal box. Pick this version when the fan connects to rectangular ductwork and you also want a pre-fitted terminal box for a quick, tidy electrical connection. The fan, motor and performance are identical across the four versions, so the choice is only about duct shape and wiring. The same size is also available as Elta SSDL125-1EC (circular spigots), Elta SSDL125-1EC-T (circular spigots with terminal box) and Elta SSDL125-1EC-R (rectangular spigots).
It sits in the middle of the three small casing sizes, all with the same 0.97 A motor and 15 kg weight. At 100 Pa it gives 547 m³/h, against 446 m³/h for the Elta SSDL100-1EC-RT and 605 m³/h for the Elta SSDL150-1EC-RT, so match it to your duct size rather than stepping up a size on the same spigot.
Installation notes
- Mount it at any angle, indoors or outside, on drop rods or Elta's SEL anti-vibration mounts (upright or inverted), make sure it is adequately supported, and leave access for maintenance.
- The inlet and outlet are rectangular spigots for rectangular ductwork. Check the spigot sizes on Elta's dimensional drawing before fabricating the duct connections.
- A terminal box is pre-fitted to one side; tell us which side when ordering. Elta's drawing shows it adds 74mm to dimension B, so allow for that in tight voids.
- Speed is set on the built-in commissioning potentiometer. To use an external potentiometer or a 0-10V BMS signal, remove the jumper link and connect to ST1; the commissioning setting then caps the maximum speed.
- Disconnect the fan before any insulation resistance testing. Elta warn this can damage the EC electronics and is not covered by warranty.
You'll also need
- Elta EC electronic controller 149-POT-10-MI (the potentiometer controller Elta list for every SSDL size)
- Elta anti-vibration mounts 062-SEL03 available to order, ask us

What is the difference between the SSDL125-1EC, -R, -T and -RT?
The -RT has rectangular spigots plus a pre-fitted terminal box. The plain SSDL125-1EC has circular spigots and no terminal box, -T is circular with a terminal box and -R is rectangular without one. Performance is the same on all four.
How much air does the SSDL125-1EC-RT move?
Up to 601 m³/h in free air at full speed, 547 m³/h at 100 Pa, 493 m³/h at 200 Pa and 302 m³/h at 500 Pa.
How do I control the speed?
The built-in commissioning potentiometer sets a single speed or a maximum speed. For user control, Elta list the 149-POT-10-MI EC controller, or you can feed a 0-10V signal from a BMS after removing the jumper link.
Can it be mounted outside or on its side?
Yes. The SSDL is suitable for external mounting and can be mounted at any angle. The motor is IP44 and the fan is rated for air from -20°C to +60°C, up to 90% relative humidity.
How noisy is it?
At full speed Elta quote 53 dB(A) at the inlet, 54 dB(A) at the outlet and 45 dB(A) breakout at 3m. The casing is acoustically lined, and 068-0125-JF spigot silencers from 300 to 1200mm long are available to order.
What power supply does it need?
A single phase 220 to 240V 50/60Hz supply. Peak current is 0.97 A, and it uses Elta wiring diagram 152-712.
