The Vents 125 Quiet-Mild TN fan is equipped with a humidity sensor. Installed directly into the exhaust shaft or using a short air duct. Maximum fan productivity is up to 185 m3/h, pipe diameter is 125 mm.
A fan with a humidity sensor is used for ventilation of rooms such as a bathroom, a laundry drying room and others. The fan automatically turns on when humidity is exceeded and runs until the required level is reached. After which it does not turn off immediately, but after the time set on the timer.
Also, the fan can be turned on forcibly using a regular switch; when the voltage supply from it is stopped, the fan will work through the algorithm given above.
The humidity level is set from 60 to 90%. The shutdown delay time can be set from 2 to 30 minutes.

Features
Quiet-Mild series silent fan – This is a well-known fan in a new design. Low noise level is combined with high performance, which makes this fan convenient for ventilating rooms in an apartment. This was achieved due to the aerodynamic shape of the impeller. The fan housing and impeller are made of plastic that is resistant to sunlight.
Special air flow straighteners are installed in the fan outlet, which reduce turbulence, increase air pressure and help reduce noise levels.
The fan is equipped with a check valve to prevent air from the exhaust duct enters the premises when ventilation is not working.
The high level of protection against water IP 45 allows it to be used for bathroom ventilation. All electronic components are closed with special sealed covers.

How a fan with a timer and humidity sensor works
Connection diagram
Fan from an external switch
The fan turns on with the light
The fan can also operate in a mode where it turns on only when the humidity level is exceeded. In this case, it is necessary to supply only the constant phase to terminal L. The fan will turn on when the set humidity value is exceeded, after reaching the required humidity level, it will run for a while according to the timer and turn off.
Installation
Fan installed in the exhaust shaft directly or using a small air duct. When installed through an air duct, the noise level increases slightly and the ventilation performance decreases.
When installing directly into a shaft, you must make sure that there is enough space from the fan pipe to the shaft wall for its normal operation. This affects noise levels and performance.
All connections between the fan and the duct must be sealed using a clamp and sealant.
Warranty
The product warranty is 5 years (60 months) subject to compliance with the rules of transportation, storage, installation and operation.
