What fan should be used for a radon mitigation system installation?
Radon fans are often oversized for the requirements. Homes that ahve a gravel base under the slab can often use a very efficient 20 watt fan especially if the slab cracks can be sealed. Homes that do not have a gravel base under the slab often require a 60 watt fan. 120 watt fans are used with homes where the mitigation systems will require high airflow or stronger vacuum to overcome the resistance of pulling air through compacted soil under the slab. If a mitigation system needs to move a lot of air the size of the pipe is more important than the strength of the fan. 3″ pipe moves up to 80 cfm while 4″ pipe moves up to 150 cfm.
