What to do if my Fantech VHR150 Fan has poor air flows?
- MMary WagnerJul 31, 2025
If your Fantech Fan has poor air flows, start by checking the following: * Clean the exterior hoods or vents if the 1/4" (6mm) mesh is plugged. * Remove and clean the filter if it's plugged. * Remove and clean the core if it's obstructed. * Check and open any indoor grilles that are closed or blocked. Additionally, an electrician should check the power supply voltage if it's inadequate. Check the duct installation in case the ductwork is restricting airflow. Increase the speed of the HRV (i.e. change unit control from REDUCED to NORMAL speed) if the speed control setting is improper. If the airflow is still unbalanced, have a contractor balance the HRV airflow. Also, have a contractor reconnect the ducting if it has fallen down or been disconnected from the HRV.
