Summary

The Elta STDL200-1EC-R is a Twinflow duty/standby centrifugal box fan for 200mm duct systems, with rectangular spigots sized 204 x 204mm. Two backward curved fans sit side by side in one acoustically lined case: one runs, the other waits on standby. At full speed it moves up to 1019 m³/h free air, about 896 m³/h at 100 Pa, and still delivers 367 m³/h against 500 Pa.

Each fan has an IP44 EC external rotor motor (220 to 240V single phase, 50/60Hz) with sealed for life bearings, and the case is 1.2mm galvanised mild steel. An auto changeover panel (149-ACO1/EDV) is fitted as standard, switching to the standby fan if the duty fan fails and sharing run hours between the two. Speed is set by the built in commissioning potentiometer or a 0-10V signal, and Elta give a 12 month (1 year) manufacturer warranty.

  • Up to 1019 m³/h
  • Speed Controllable

What it is best used for

Mid size extract on 200mm ducting where continuity matters: multi cubicle toilet cores in offices and schools, classroom and library extract, hotel corridor and bathroom riser systems, and small kitchen general ventilation. It moves 1019 m³/h free air and about 763 m³/h against 200 Pa.

It is mounted horizontally only and is rated for air up to +60°C, so it is not suitable for hot, grease laden kitchen canopy extract or corrosive or explosive atmospheres.

Why choose this over alternatives

The point of a twin fan is resilience. A single fan such as the Elta SSDL200-1EC-R Singleflow moves more air in the same duct size (1148 m³/h free air against 1019 m³/h here, and 436 m³/h at 500 Pa against 367 m³/h), but when its motor fails the extract stops until someone replaces it. The STDL200-1EC-R keeps running on its standby fan, the panel gives normally open fail and run contacts for a BMS or alarm, and the duty share means neither motor does all the hours. Choose it for windowless toilets, risers and any system where a dead fan means a complaint or a breach of the ventilation design; choose the Singleflow where a short outage is acceptable.

This model has rectangular spigots (204 x 204mm). If your ductwork is round, the Elta STDL200-1EC is the same fan with 200mm circular spigots. For less air, the Elta STDL150-1EC-R gives 493 m³/h free air. For more, the Elta STDL250-1EC-R gives 1210 m³/h.

Installation notes

  • Mount the fan horizontally only. Elta show it fixed directly to circular or rectangular duct, inverted, on AV mounts or hung from drop rods, and leave access for maintenance.
  • Bring the 220 to 240V single phase, 50/60Hz supply to the terminals of the fitted auto changeover panel and provide a local means of isolation. Wiring diagram 152-717 applies.
  • Set the maximum speed on the 149-CD-POT commissioning board. For external control from a potentiometer, the 149-POT-10-MI or a 0-10V BMS signal, remove the jumper and connect to terminals ST1; the board setting then caps the top speed.
  • The panel's test jumper shortens the duty share switching time from 12 hours to 1 minute, so you can prove the changeover works at commissioning.
  • Disconnect the EC fans before any insulation resistance testing. The electronics can be damaged and this is not covered by warranty.

What does duty/standby mean on the Elta STDL200-1EC-R?

There are two fans in one case. One runs as the duty fan while the other stands by. The fitted auto changeover panel starts the standby fan automatically if the duty fan fails, and it also swaps the fans over on a timed duty share so the run hours are spread across both motors.

Do I need to buy a separate changeover panel?

No. The 149-ACO1/EDV auto changeover panel comes fitted, and the mains supply connects straight to it. It provides normally open fail and run contacts so a BMS or alarm can see a fan failure.

How much air does the STDL200-1EC-R move?

Up to 1019 m³/h (0.283 m³/s) at free air on full speed, about 896 m³/h at 100 Pa, 763 m³/h at 200 Pa and 367 m³/h at 500 Pa.

How do I control the fan speed?

Set a single fixed speed on the built in 149-CD-POT commissioning potentiometer, or remove its jumper and wire in the Elta 149-POT-10-MI controller or a 0-10V BMS signal. The commissioning setting then acts as the maximum speed.

What duct size does it connect to?

It has 204 x 204mm rectangular spigots. The STDL200-1EC is the version with 200mm circular spigots.

Can it be mounted vertically?

No. Elta state the STDL must be mounted horizontally. It can be fixed to the duct, inverted, set on AV mounts or hung on drop rods. It weighs 40 kg, so make sure the fixings are rated for it.
