The amount of radon in the air is measured in “picocuries per liter of air,” or pCi/L. Roughly 1 out of 15 homes in the United States has elevated radon levels (4 pCi/L or greater). A fan performance spec is given as a Fan Total Pressure or a Fan Static Pressure which can handle a certain flow rate. To calculate the pressure loss incurred by such a configuration, consider two elements at a time. Multiply the specified operating static pressure by the correction factor to determine the standard air density equivalent static pressure. Fan ratings based only on static pressure are partial, but commonly used. Using electricity isn’t a good idea either or you’d have to provide heat shielding for the wiring.
Just about every great fan I’ve installed has good instructions that discuss the minimum requirements for running the exhaust piping. Failing to do so can void the fan warranty in many instances. There is no way to keep from overpowering the bathroom fan. There is no way to completely seal off the dryer air from the bathroom. Debris pushed into bathroom, in spite of the possible built-in damper. In some communities, this section may be in lieu of Section R303.3 or in addition to it. Be sure to clarify this with your local permitting department. There are many benefits of adding a bathroom fan to your bathroom, but you may still have some questions about choosing the right fan for your space.
A radon vent fan should be installed in the ventilation pipe if testing indicates radon concentrations are greater than the EPA’s action level of four picoCuries per liter (4 pCi/L). Radon fan (i.e., an active system) OR an electrical receptacle installed in an accessible attic location near the radon vent pipe (i.e., a passive system) to facilitate future fan installation if needed. A space surrounding the radon pipe, having a vertical height of not less than 48 inches and a diameter of not less than 21 inches, shall be provided in the attic area where the radon fan can be installed, if required. So I’ve installed metal duct from my bathroom exhaust fan to the gooseneck vent on my roof. We have a train that comes close to our house and when the fan isn’t running and the train blows it’s whistle the sound reverberates down the pipe into the house. Do you have any solutions for dampening noise that comes through the pipe into our home. They took their fantastically popular Premium 4 stove top fan, removed the base which would have stood on the stove top and replaced it with a magnetic attachment they call ‘wings’. Broan-NuTone™ exhaust ventilation fans allow your home to exhale, eliminating humidity, odor and airborne particulates from your bathrooms, closets, mud room, laundry, work out space and more. Ventilation fans improve indoor air quality by venting moist air quickly outside, which helps to control mold and mildew growth.
Install a continuous layer of polyethylene vapor barrier with joints taped over the soil. Run the polyethylene sheet up the wall and mechanically attach and seal the edges to the wall. Seal the vertical “T” to the polyethylene to reduce the soil gas entry. Seal the perimeter of the “T” to the concrete to reduce the soil gas entry. See the following guides for more information on air sealing and vapor barriers for basements and crawlspaces. The amount of radon in air is measured in “picocuries per liter of air,” or “pCi/L.” The average outdoor radon level is 0.4 pCi/L.
My first piece of advice is to buy the best fan you can afford. Fans that cost more money are almost always made with better parts and better motors, and they’re not noisy. You should run the fan for about 20 minutes during and after a bath or shower. That will help the fan fulfill its intended purpose of controlling moisture in your bathroom. If you run the fan constantly the ball bearings inside will lock up. Because windows provide light as well as ventilation, if you go the fan-only route you need to install artificial lighting. This should already be a given, as electrical code requires that habitable rooms be supplied with a switch-controlled light. Building code is a model code that each community can adopt and adapt according to its own needs. So, you will need to check with your city or county planning and permitting department to find out code requirements regarding bathroom fans.
During heavy rain, water comes out of the exhaust fan in my first floor bathroom. No, it’s never a good idea to have any exhaust fan in your home dump all that hot, moist air in your attic. It can cause you a lot of problems with mold and mildew forming on the underside of your rafters and decking as well as getting into your insulation.

Even better would be using 4 inch rigid duct up to a reducer right at the roof, especially if the run is more than a couple of feet.
Energy Star–certified ceiling fans use an average of 70 percent less energy than their less-efficient counterparts. Suppose your bathroom is 8 feet wide, 10 feet long, and 8 feet high. In this case, a fan with a CFM rating of 80 would probably be sufficient for your bathroom. Be sure to talk to the manufacturer about the best way to connect this pipe to the fan and fittings if you decide to use it. RadonSupplies has a 1 inch fiberglass lined muffler inside a 6 inch PVC S&D pipe. This muffler provided the least airflow resistance and the greatest DB reduction. There are many questions when setting up fan coil thermostats.
Many manufacturers today produce bathroom fans that operate quietly. If you’re very concerned about sound, consider installing a 6-inch ducting attachment for your fan rather than the standard 4-inch attachment. Air can move easier in a wider duct, so a 6-inch duct puts less strain on the fan and allows for quieter operation. As with purchasing any new appliance or electrical product, consider energy efficiency when shopping for a bathroom fan. Fans that are energy efficient use less energy than other models, meaning that they can help you save on your monthly electric bills while also decreasing your home’s environmental footprint. This setup moves the fan a bit farther from the bathroom ceiling for reduced noise and vibration.
The diagram below illustrates the difference between exhaust and supply systems. Fan total Pressure is the pressure differential between the inlet and the outlet of the fan. The effect is to increase the energy or pressure in a system as air flows through the elements. System Effect occurs in an air system when two or more elements such as fittings, a hood and a fitting, or a fan and a fitting occur within close proximity to one another. In the example below, the actual pressure loss would be somewhere between -0.75” and -0.6”. In other words, more air flows through the branch with the lower pressure loss/gain or energy state.

Also, make sure the damper at the fan itself is working so moist air from the bathroom doesn’t constantly leak into the duct, where it will condense and freeze, even when the fan isn’t running. It can also help to start running the fan before showering, which will draw warm interior air into the duct run and help warm it up before you really start injecting a lot of steamy air. Finally, I recommend using a metal wall cap instead of a plastic one. Metal is highly conductive, and warms up faster when the fan is running. The 0-10 Volt signal voltage can be set via a simple potentiometer and left or the 0-10 Volt signal voltage can be delivered to the fan motors by the terminal controller on each of the Fan Coil Units. The former is very simple and cheap but the latter opens up the opportunity to continuously alter the fan speed depending on various external conditions/influences.

Surface-mounted permanent PVC or PE pipes are pulled out and set aside at the end of a cycle while the loader tears down the pile. Entrenched piping is left in place without fear of mangling during teardown, though it does get cleaned and reused for the next cycle. The 4-inch PVC pipe sells for $3.54/linear foot while 4-inch PE pipe is $3.28/lf. Laying pipes in concrete is the most costly option and should only be done after the process has been refined. The other two options are best if the facility is in developmental stages and might be modifying the process. Guidebook providing useful examples of high performance retrofit techniques for the building enclosure of wood frame residential construction in a cold and somewhat wet climate.
