Install the concrete slab or polyethylene vapor barrier or both over the ground. Ensure that the slab and/or vapor barrier do not cover the vertical opening of the T connector but are sealed around it. Lay a perforated pipe or a collection mat around the interior of the foundation perimeter and insert a vertical “T” pipe connector to the pipe or mat. Eliminate hot and cold spots in your greenhouses, factories, or any controlled environment with tube fans. We offer duct/pit fans from DURAFAN, as well as stainless steel tube fans. If that was not bad enough, the fans in the video believed it to be a sewage pipe. We’ve also seen homeowners have to replace all their roof decking because it became rotted from the excess moisture. VersaSpeed ™ Fan Ramp Algorithm automatically adjusts Low, Medium, High fan speed. OdorHogs will only eliminate odors that originate at the plumbing vent stack on the roof. Most homeowners can attach the filter themselves in minutes.
I use metal plumber’s tape—it’s a galvanized strapping with holes every 1/2 inch for screws. In order to keep the fan effective, try to lay out your installation with minimal turns. Determining the minimum CFM of your bathroom is easy, simply multiply the room’s width × length × height × 0.13. Inspect the framing to determine the best duct path and mounting position for the fan. Moist air can also work its way into a wall cavity and condense inside the wall. Both situations can result in mold, odors and sometimes structural damage. Prior to and even during a bathroom remodel, I often have conversations about tile and fixture layout, style and finish. But the conversation seldom leads to discussion of bathroom ventilation, issues like CFMs, minimizing ductwork and the placement of external heads and backdraft dampers.
The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments. Radon fan motors vary considerably in the noise they generate. Often a fan with higher wattage than required is used because the installer does not measure the depressurization induced under the slab. A lower wattage fan can almost always be installed in standard radon sub-slab depressurization systems if there is good aggregate under the slab and the slab does not have large open cracks or other unsealed openings.
You will be hard pressed to find a better stove fan anywhere else. We’ll take a look at the five models they offer, and we’re sure you’ll agree, these fans are an amazing value for the money. The Hunter Sona uses two 60-watt light bulbs to provide illumination and includes the option to install a smaller 7-watt bulb for a soft nightlight. People agree that this exhaust fan for bathrooms looks beautiful and could easily be mistaken for only a light fixture. However, the frosted coating on the dome does diffuse the light, so you will need a second source of light in the bathroom as well. This budget bathroom exhaust fan operates at about 4.0 sones, which is considerably louder than other models. However, the increased noise level might be a good match for providing bathroom privacy. Panasonic makes some of the most popular models of bathroom exhaust fans, and the brand has a reputation for quiet operation. It lives up to this reputation with the Panasonic WhisperCeiling DC Fan.
Users can choose to wire the light and fan to the same switch or wire them separately depending on their needs and preferences. The manufacturer includes all the necessary hardware for installing this flush-mount fan. Remove the chrome finial and glass cover when needed for easy cleaning or to change the bulbs. When producing this Energy Star–rated model, the manufacturer relied on high-quality elements and included a permanently lubricated motor for reliability and lasting operation. Installation is straightforward, and the adjustable mounting brackets and 4- and 6-inch duct options allow for flexibility. The branch circuit in this model is GFCI-protected for a longer lifespan and increased durability. Installation is relatively straightforward with the included keyholed mounting brackets and a tapered, polymeric duct fitting. Fans that cost more money are almost always made with better parts, better motors and they’re not noisy.
With no bathing facilities, far less moist air is produced. While powder rooms can benefit from exhaust fans, they can usually operate just as well with a window that opens. After searching through an array of ventilation systems available for bathrooms, the top picks represent some of the most thoughtfully designed and reliable options. The models featured in this guide are all from trusted manufacturers with a demonstrated history of producing quality bathroom fans. With the torsion springs grille mounting, no tools are required for either installation option. This bathroom ventilation fan features a permanently lubricated motor to ensure long-lasting operation. When installing a bathroom fan, the best location is typically between the shower and toilet, in an area of the ceiling without any obstructing joists or pipes. Replacement fans should be installed in the same location as the existing fan. When you draw moisture-filled air out of the bathroom, it needs somewhere to go. Some bathroom vents release exhaust into a home’s attic; however, this setup isn’t ideal, since excess moisture in the attic can lead to mold-related issues.
They endure factors such as heat and vibrations they encounter during operations to sustain their ideal performance levels. These are easy to install and maintain, especially because of their minimal rates of breaking down and the readily available spare parts. This makes them suitable and practical for many areas, including homes, offices, institutions, and virtually any other areas that require uniform airflow.

Rigid duct is better than flex duct, and bigger duct is preferable, especially if the runs are long. Use a high-powered fan and a large-diameter duct with the shortest run possible, and wrap the pipe with insulation. In high-rise buildings, fan coils may be vertically stacked, located one above the other from floor to floor and all interconnected by the same piping loop. Fan Coil Unit covers a range of products and will mean different things to users, specifiers, and installers in different countries and regions, particularly in relation to product size and output capability. When moisture spreads in a home, one thing quickly leads to another. When these cellulose-hungry insects begin feeding on your home’s wood framework, you need to act quickly. Costs spiral from there as you put the home under a pest control contract and undergo extensive remodeling work to shore up weakened studs. Bathroom venting fans are about more than just eliminating noxious odors. Bad odors are annoying but are hardly life-threatening, and they do not impact the integrity of the building structure at all.
Among the top picks, the Broan-NuTone Ventilation Fan stands out for its quiet operation, ease of installation, and HVI-certified ventilation performance. The KAZE APPLIANCE 200 CFM is a worthy choice for large bathrooms, offering powerful airflow, energy efficiency, and universal installation options. This practice provides the design details and construction methods for two built-in soil depressurization radon control and reduction systems appropriate for use in new low-rise residential buildings. “This practice provides the design details and construction methods for two built-in soil depressurization radon control and reduction systems appropriate for use in new low-rise residential buildings. Velocity is calculated from the flow rate of air through the ASP or biofilter in conjunction with the pipe diameter. Friction factors come from the Moody Friction Factor Chart and depend on the relative roughness and specific roughness, which are available on various charts.
As shown above, Branch 1 of the junction is used to calculate the system’s total pressure loss because it has the greater pressure drop of the two branches. We will illustrate how once you know one (CFM, S.P.) point of a system you can use the Fan Laws to calculate the pressure loss for other air flow rates. This means that whenever air flow encounters a junction it will take the path of least resistance and the total pressure losses of each branch of the junction will be the same. This curve shows the relationship between the air flow rate and the pressure of an air system. The relationship between the air flow rate and the pressure of an air system is expressed as an increasing exponential function. The measurement of the energy level in an air stream is uniquely represented by total pressure only. The pressure losses in a duct are represented by the combined potential and kinetic energy transformation, i.e., the loss of total pressure. Things are much easier with the Stirling powered fans like Vulcan or Warpfire, where there’s no temp difference required – just the heat from the stove. Stirling powered fans are not as vulnerable and withstand much higher temperatures. So if your stove usually gets very hot you might want to consider this kind of fan – especially if you have big area to push the warmth around.
Install a passive radon venting system if the home is located in Radon Zone 2 or 3. Lay a perforated pipe or a collection mat around the interior of the foundation perimeter and insert a vertical “T” pipe connect to the pipe or mat. This illustrates how low the pressure really is when a system is designed for the desired velocity between 900 and 1000 ft/min. The entire system satisfies the definition of a section since there are no junctions or duct size changes. The second part of the problem will calculate the pressure gain of the system and compare it to the measured pressure gain. Since Section 1 has a larger duct size, this section is the “u“ side of the bullhead tee. Calculate the pressure loss/gain associated with each fitting as if it occurs alone. In this example we calculate the pressure losses for Section 1 to be -0.75” at the junction.
Another complicating factor in induced-draft systems is the condensate that comes when pulling air through moist compost. Allow some means for draining it from the piping or ducting coming from the blower. This can consist of a drainpipe with a valve affixed to it in each low spot in the piping. If the pipe is small enough in diameter, it can be run into the side of a 55-gallon drum, near the bottom, and exit on the other side, near the top. Place a sump pump with a float switch inside the drum to remove condensate that collects. An interesting option offered by a few companies for the pile piping is a prefabricated product that has pipe with properly sized orifices already in it. This type of aeration floor, supplied by BuildWorks, is being installed at an ASP retrofit project for the Wasatch Integrated Waste Management District in Layton, Utah. Typically, one blower serves each ASP; in an induced draft system, several blower outputs may be piped to a manifold, which then goes to one biofilter.
There is one more stove fan dedicated to work on the beautiful soapstone, gas or convergent stoves – the Ecofan BelAir. It was introduced by the pioneering stove fan manufacturer, Caframo – based just 150 miles away from London… in Ontario, Canada. The Ecofan Belair is less than 160mm high, and has been fitted with two Peltier modules to provide enough energy to propel 140 CFM. This marginalised a huge chunk of the market, and a solution had to be found sooner rather than later. It is also a good solution for the stoves that are designed with a decoration on top, or are simply not perfectly horizontal for a stove fan to sit on. To attach the Remora stove fan to your flue pipe you simply fold back the magnetic wings and when the fan is in the right place the wings are gently returned to position around the flue pipe and secured in place. When folding the wings back in place around your flue pipe, be careful not to let them snap in place as it could damage the magnets. The fan has to be a minimum of 20cm away from the stove top so the blades are clear when they spin and also avoids overheating the motor inside. The magnets on the wings are able to hold in place to well over 400°C.
