  • 100mm recessed centrifugal flow fan for bathrooms and WCs


  • Can be installed in wall, ceiling and panel mounting applications

  • Centrifugal pressure handling allows installations with up to 10m of 100mm ducting


  • Simple screw fix design for fast ceiling installations 


  • Design includes anti-backdraught shutters to reduce unnecessary heat loss in homes when the fan is not in operation


  • Discreet, modern front fascia design which easily blends with today’s modern décors

What else should you know about RF90?


  • Cost comparison - how much is the fan actually costing tenants?     
    A 1000W microwave costs £12.72 per year to run based on 15 minutes usage per day.
    This is the equivalent of running 8 RF90 fans for the whole year based on 1.5hrs usage per day

    You do the maths... OK, it's £1.59 to run RF90 for the entire year! 


  • Free recycling scheme available
    It's simple really.... you choose Greenwood fans to replace others (Greenwood or not) and we will organise all of the replaced fans to be recycled. Call us for more information about this scheme which is running nationwide now.
