Duct Size and Type

Determining the appropriate duct size is crucial. The duct should match the fan's CFM (cubic feet per minute) rating and the size of the bathroom. Common duct sizes range from 4 inches to 8 inches in diameter.

Various duct materials are available, including flexible aluminum, rigid PVC, and galvanized steel. Flexible aluminum is easy to install, while rigid PVC offers durability and is less prone to kinking.

Installation Techniques

For flexible ducts, use duct tape or aluminum tape to seal the connections. For rigid ducts, use duct clamps or screws to secure the joints.

Ventilation Efficiency

The replacement duct should improve ventilation efficiency by providing unrestricted airflow. Choose a duct with a smooth interior surface and minimize bends or kinks.

Consider using a duct booster fan to enhance airflow if necessary, especially in larger bathrooms or those with long duct runs.

Safety Precautions

Always disconnect the fan from the power supply before working on the duct. Wear safety glasses and gloves to protect yourself from sharp edges.

If the duct passes through insulated areas, use fire-resistant insulation to prevent fire hazards.
