Solar Room Ventilators

Solar Room Ventilators


Transfer air from one part of a building to another.   

  • Share warm air from near a wood heater to heat a cold bedroom down the hall
  • Remove damp air out from a cold bathroom to prevent mould growth
  • Circulate fresh air through a walk-in robe, etc.   
  • There are endless applications for using a small solar-powered fan to move air from one place to another.   


1. Remove hot, humid, or stuffy air directly to the outside.

  • From an adjustable ceiling vent located somewhere central in the room, the duct goes to an inline fan and vents to the eaves outside.
  • The quiet extractor fan automatically runs on any sunny day, just from the sun.
  • Or temperature control it using an adjustable thermostat.
  • Ceiling vents are closed to prevent heat loss on cold nights.

 2. Remove heat and odours from Ceiling to Roof 

Perfect for removing heat, stale air, and bad smells all day from the ceiling of a room or corridor, and exhausting it directly to the outside, using a solar ventilator mounted on the roof.    This system has been particularly useful in removing offensive stale air and smells from closed, air-conditioned, buildings such as nursing homes and chemical stores.   Further uses have been found in reception areas of doctors’ and dentists’ clinics, where contaminated air from patients to others must be avoided.

Mini fans units are capable of ventilation either through air extraction or by introducing fresh air.
