TRIO 100 Humidity Sensor 100mm designer fan

Blauberg Trio is a popular choice of fan, sensibly priced and still meets Building Regulations. High airflow rates are achieved with low noise levels due to the unique coupling of mixed flow technology with our energy efficient Blauberg German motor.

Blauberg Trio is slimline, with clean lines and will suite any contemporary bathroom, en-suite or toilet. It will also blend into any white wall or ceiling due to its brilliant white finish.

This 100mm, 4" dia bathroom version has a built-in humidity sensor and over-run timer. It requires live, neutral and switch live wiring connections. This will allow the fan to continue running for up to 30 mins after the fan has been switched off (part of building regulations for toilets that do not have opening windows) .It is also fitted with a simple back draught shutter to reduce wind and drafts entering back into the room.

Blauberg Trio is Building Regulation Part F and L compliant with very low specific fan power at 0.32 w/l/s, meeting all the energy requirements to date.
