Continental Fan's new CF Bathroom Exhaust Fans provide an economical bathroom ventilation solution. CF Fans are available as complete fan assemblies or in easy-to-install contractor packages. The built-in damper prevents a backdraft, keeping tempered air in the home when the fan is not operating. The clean and simple grille design is suitable for all interiors. How much airflow is required? HVI 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. What is HVI? HVI, also known as the Home Ventilating Institute, is an independent non-profit organization that certifies fan performance characteristics and provides HVAC guidelines for consumers. All AeroFan models are HVI certified.
