Fantech ProVent In-Line Duct Fan RIL-125 150SW 200SW

Mixed-flow in-line fans built for ducted supply or exhaust air. Mount them in the ceiling space and away from the room, so you get the airflow without the noise sitting over your head.

What you get across the range

• Mixed-flow impeller — moves serious air against duct resistance, where an axial fan would stall. Reinforced injection-moulded polypropylene housing, moulded plastic impeller.
• Serviceable without pulling the duct apart — the fan body lifts out on purpose-designed support brackets. Anyone who's tried to service a fan buried in a ceiling will know what that's worth.
• Integrated mounting foot — fixes off cleanly instead of being strapped up and hoped for.
• Plug and lead included — standard models come with a 2-pin plug to suit HPM 37CL or Clipsal 413-WE bases with 3-pin sockets.
• Mount in any position — vertical, horizontal, on its side. Suits both supply and exhaust.

The 150SW and 200SW include an external 2-speed switch. The 125 doesn't — it's a 2-speed motor, but you'll need a separate switch or VA-type speed controller if you want low speed.

⚠ Sizing note for the 125

Fantech specifically advise against spring-loaded backdraft dampers, long duct runs and air valves on the 125mm model. It hasn't got the static pressure for them. If your run is long or you need a damper, step up to the RIL-150SW — it's the more forgiving fan and it's not much more.

Speed control

These can be speed-controlled with a VA-type controller, but only from the high-speed setting.

Installation

The fans are plug-in, but the socket base in the ceiling is electrical work and must be installed by a licensed electrician.
