About This Product

A radon fan doesn't have to look industrial to be effective! Our Rn2SL is engineered specifically for the demands of radon mitigation applications with aesthetics in mind. This exterior-mounted fan features a sleek, neutral-colored housing that is less contrasting to the appearance of many homes' exteriors. The fan connects directly to the system pipe via included connectors. The fan's inlet connection is located on the back of the housing, so that it connects to the pipe where it comes through the wall. This eliminates the need for a pipe elbow, and conceals the wall penetration from view. The fan's discharge is located on top for connection directly to the vertical pipe riser.

Highlights

  • What comes with Rn2SL inline radon fan: flexible sleeve coupling and stainless steel hose clamp for fan inlet connection to 4" PVC pipe; flexible, gray coupling and (2) stainless steel hose clamps for fan discharge connection to 4" PVC pipe; wall bracket for support via hose clamp connection to a vertical pipe riser
  • Inconspicuous appearance
  • Factory sealed, no leak design
  • Integral condensate bypass
  • Exterior-mount close to the wall

Answer This Question

Sorry I am not certain I completely invasion your question. If you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find PDFs of the product documents. The Specification sheet contains an illustration giving dimensional information. It shows that the unit is mounted flat to the wall and will protrude out 51/2” from the wall.

    Answer This Question

    Radon fans typically terminate at a point equal to or above the roof line. This is done to prevent radon from reentering the home. There are some limitations to this. As I am not familiar with your system or local building codes I cannot give you a definitive answer. I would suggest you speak to the person who installed the system or a local qualified radon specialist to see if a change in the discharge location is possible in your case.

      What is the CFM rating on this? thanks,

      Answer This Question

      As indicated in the description this fan has a rating of 159CFM, when there is zero resistance. The resistance often called static pressure drop is created by the friction of the moving air against the duct work. For this reason, like pumps, fans are rated on a graph called a curve. One one axis you have the movement of air expressed in this case in CFM, cubic feet per minute. On the other axis you have resistance expressed in inches of water column. The curve illustrates fan performance at all these points. So it is possible to look up the resistance created by the footage and type of duct work you are using, as well as the fittings, and determine what the final fan performance will be when installed in a system. The curve can be found on the product brochure. A PDF of which can be found on the Home Depot product listing page under the header of info and guides.

        The Fantech Slimline 159 CFM fan has been performing excellently....
        The Fantech Slimline 159 CFM fan has been performing excellently. The unit has helped in lowering the radon levels in our home from around 6.7 to 0.5 pCi/L. The soil under our basement slab (approximately 1300 sq/ft), where the suction pipe is located, is mostly coarse sand with native gravel. It is important to remember that the fan is one component contributing to the performance of your radon system. Therefore, you should do an initial assessment to see if this fan is right for your home.
