This kit includes:

  • One (1) Fantech Rn3 Radon Mitigation Fan
  • Two (2) 4x6" rubber flex couplings (choose color to fit your system)
  • (1) U-tube manometer to easily see that your fan is working
  • (5) System labels to make your system compliant with radon mitigation standards


The Fantech Rn3 is an excellent choice for elevated radon levels, poor communication, multiple suction points, and/or large sub slabs.

The Rn3 replaces Fantech model HP220.


Note: Utility cords need to be purchased separately. The Rn3 has 4" openings thus requiring 4x6 rubber couplings for mounting. You must use 4" PVC. Varmint guards are a must to protect your fans warranty (sold separately).
