TF140-EC Tranquil Bathroom Fan

Description

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.

How much airflow is required for bathroom ventilation?

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.

• A bathroom less than 100 square feet:
  • Calculate 1 cfm per square foot of floor area. A minimum of 50 cfm is the required ventilation rate.
• A bathroom larger than 100 square feet:
  • To calculate the proper ventilation rate, add the cfm requirement for each fixture; toilet 50 cfm, shower 50 cfm, bathtub 50 cfm, jetted tub 100 cfm. Note: For proper sizing, the static pressure (SP) needs to be calculated.

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.  Learn more in our blog posting: what-is-the-best-duct-for-bathroom-ventilation.
