    Rated 5 out of 5 by from exact replacement This NuTone ILRF Radon exhaust fan was provided by Venting Direct as an exact replacement for one which failed at my house after eight plus years of continual 24/7 service. The original fan re mediated radon from underneath our basement concrete slab and vented it through the roof of our house through all seasons here in Pennsylvania with no noise or failure for those eight plus years. Apparently, the bearings or some similar part of the original internal fan finally succumbed to the elements and needed to be replaced. Venting Direct provided the replacement in a courteous, reasonable, and prompt manner. It was very simple for me to replace the original, even though it is at a part of the attic which is trouble some to work in. I feel the original unit lasted very well, and would highly recommend this fan to anyone needing a similar device.

  • is this fan suitable for attic installation seeing that it is a long draw from basement ?

    current fan is in attic. radon pipe comes up through floor slab in basement
    Asked by: miko
    Thank you for your question on the model ILRF in-line radon fan. There is no problem installing the fan in the attic as long as the duct work is not too long. Using four inch rigid duct work you can run the ducting 16 feet straight, reducing that distance by four feet for every elbow. Using five inch rigid duct work you can run the ducting 48 feet straight, reducing that distance by five feet for every elbow.

    Can this fan be used to boost an existing fan in a humid bathroom?

    I have a customer who is using the combination fan/heater light unit you sell which uses the 2-250 watt heating lamps. They don' t often use the heater, but the fan doesn't seem to be removing enough of the moisture from the bathroom to avoid paint damage due to water collecting and running down the ceiling/walls. My secondary question would be, "Could I mount this or another remote unit in the alcove above the shower, with ducting to a vent cover in the shower, and add a "Y" adapter to connect to the existing fan, which is centrally located in the bathroom(outside of the shower)?" Thank you!
    Asked by: ContractorR
    Thank you for your question s about your NuTone 9427P. The 9427P uses 4”round duct and produce 70CFM. You should check the duct work to make sure there are no restrictions and that there is smooth air flow out the roof or wall cap. In answer to your second question, the ILRF would not be the correct ventilation product to use for this application. However, you could use an Inline fan possibly the ILF120 for more ventilation in the room, but a “Y” adaptor could not be used to connect the other fan. Please contact our technical service department at 1-888-336-6151 to discuss your particular application in greater depth.

    Were do I find the coupling for this Nutone ILRF Radon fan for a 3" PVC pipe

    Asked by: John
    Thank you for your question on the model ILRF radon fan. I’m sorry, but this fan is not designed to be used with three inch ducting. It is designed for either four or five inch ducting.

    can we reduce the vent pipe size to 3 in ?

    Asked by: bernie
    Thank you for your question on the model ILRF in-line radon mitigation exhaust fan. The ILRF requires the use of either four or five inch, preferably rigid duct work. We do not suggest or recommend using anything smaller than four inch duct.
