Residents forget to turn them on so things go mouldy or forget to turn them off so the fans run all day.
A current sensing switch fixes this automatically – when a dryer draws current above a set threshold the exhaust fan turns on. When the dryer stops, the fan stops.
No extra switches. No resident involvement. No wasted energy.
We’ve been making these in Australia for over 50 years.
