TF140-EC Tranquil Bathroom Fan features an electronically commutated (EC) motor that provides superior ventilation and efficient performance. This versatile fan can be installed as a traditional bathroom fan. Alternatively, it can be configured to operate continuously at a low airflow rate to improve indoor air quality (IAQ). When the fan’s humidity sensor detects a change in environmental conditions, the fan will boost automatically to a maximum pre-set desired airflow. Toggle-switch positioning determines the maximum desired airflow rate, ranging from 80 to 140 cfm. The built-in time delay, humidity sensor and motion sensor simplify operation.
A full range of accessories is available to suit each application from mounting clamps to flexible insulated duct to roof caps (see all available fan accessories).

HVI, also known as the Home Ventilating Institute, recommends ventilation rates based on 8 air changes per hour. For most bathrooms, this works out to 1 cfm per square foot of area with a minimum of 50 cfm.

When it comes to choosing the right duct, people often ask, “What is the best duct for bathroom ventilation?” While there isn’t necessarily one absolute right choice, many times the best option is the flexible insulated duct.
