Fans High Suction

Most radon mitigation fans fall into two categories: high-suction or high-volume, except the dual-category Rn4EC.  High-suction radion mitigation fans typically move more air when encountering high resistance.  These fans work best with a difficult or smaller pressure field extension and “tight” soil conditions.  Fans in this category include the Rn4EC and the GP series by RadonAway.  These high-suction radon mitigation fans perform better than other fans in “tighter soils” or low pressure field extension.  For accurate fan sizing: utilize a micromanometer, the pressure field extension diagnostic kit, or call PDS!
