Larger model of this fan, normally used in kitchens or utility rooms. Not normally used in bathrooms or toilets. Humidistat level can be adjusted 40-90% relative humidity. Ducting not included. This model incorporates a condensation (humidity) sensor which automatically switches the fan on when the condensation level builds up.
I had been looking for this product as a replacement for the one that had been in use for several years. It is a very efficient product and is quieter than my old model.I am told that it was easy to install and it fits the hole where the old one was,which is a bonus. It is very efficient also. Can definitely recommend.
