Radon Fan

We are always making improvements in the safety and longevity of our systems so that we can better serve our client for many years to come. We can paint the exterior exhaust pipe to match the exterior of the home. An on/off switch is installed within 4′ of the radon fan and in view. The electrical and pipe penetrations are sealed with caulk to make them watertight. The represents the most striking cost difference between a Whalen Innoline® 50/50 Four Pipe System design and a conventional 4-pipe system. The Innoline® 50/50 System allows design day operating costs to be incurred only when necessary. Axial fans use a propeller, having two or more blades, to move air in an axial direction through a cylindrical housing or formed orifice panel.

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.

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.

Fill it with enough water so that the stem of the mouthpiece is slightly submerged. Tape both cans together to create the full chamber of the water pipe. If you’ve got something to smoke and nothing to smoke it out of but some soda cans, you’re in luck. It’s easy to make a basic pipe or a more elaborate water-pipe to smoke form. Bathroom vent ducts must always terminate on the outside of the house. Here’s the interior exit point where the duct terminates the vent hood. Take steps to properly support your pipe run either from below, with blocking or from above, with plumbing strap or large, heavy-duty cable ties .

Select the location for the ventilation pipe to be installed in a vertical run through a warm part of the house and exhausted through the roof. The pipe discharge should be installed at least 2’ above the roof and 10’ away from any openings in the building to keep the soil gas from re-entering the building. Static pressure is the measure of the potential energy of a unit of air in the particular cross section of a duct. Imagine a fan blowing into a completely closed duct; it will create only static pressure because there is no air flow through the duct. If you don’t have access to an external vent but still want to improve circulation and air quality, consider a duct-free bathroom exhaust fan. The Broan 682 utilizes a fan to produce air movement and a charcoal filter to absorb odors. Heat things up while keeping moisture away, thanks to a bathroom exhaust fan with a heater—like the Broan 9093WH. This combo model includes an exhaust fan, an onboard heater, and a light. The Broan 688 is rated for 50 CFM and is the best fit for small bathrooms of under 50 square feet.

When installing a bathroom fan, it is important to vent it to the outside, either through the attic or a sidewall. If bath fans are not vented outside, you’ll simply be moving the moisture to another area in the home, where it may cause problems. This model is designed to be easy to install for professionals and home users alike. As the name implies, ceiling fans are mounted in the ceiling of a bathroom. An air intake vent sits right in the ceiling, with the fan portion directly above it. The fan pulls air from the bathroom up into the vent by creating suction and then releases it through the roof vent on the other side. Moisture buildup in the bathroom also encourages mold growth in drywall and caulking, threatening indoor air quality. The best bathroom fan removes excess moisture effectively, protecting your bathroom from water damage while helping eliminate mirror fog and odors.

Motion and humidity sensing fans are a hands-free solution to fighting excess humidity that employ unique sensing technology. Our chimney fans offer masonry adaptors to fit and work with a square or rectangular masonry flue. The Auto-Draft needs to pull adequate air through the stove to run properly. Make sure your stove has some type of air shutter door or air intakes to satisfy draft. The burning of such woods as pine, fir, etc. produces a tar-like substance known as creosote which can coat the interior of the chimney and Draft Inducer. Stack temperature may become high enough to ignite the deposits and cause a chimney fire. Become a member and get instant access to thousands of videos, how-tos, tool reviews, and design features. Fan coil units may be connected to piping networks using various topology designs, such as “direct return”, “reverse return”, or “series decoupled”. See ASHRAE Handbook “2008 Systems & Equipment”, Chapter 12.

A quality bathroom fan, properly installed will remove moisture and odors from your bathroom and will improve your indoor air quality. The Sirocco, produced in Lithuania by the German company – Hansa, has been one of the first stove fans on the European market. Weighing nearly 2kg, it’s quite heavy when compared to other Peltier stove fans. It has a massive heat sink which secures energy accumulation, so the fan works long after the fire in the stove dies down. The fan’s base is equipped with three screws which act as feet and six threaded holes so the fan can be levelled if the stove top surface isn’t perfectly horizontal. Another purpose of the countersunk screws is to lift the fan so it stays away from a stove top that might get too hot for the fan’s motor and Peltier module. Stove fan manufacturers follow very similar requirements when designing their models. If you’re not especially technically inclined, you might want to consider the largest and probably the most powerful Peltier powered stove fan by Valiant, the Vanquish 250. This model was introduced to the market last year , is 250mm high and has two aerodynamically profiled blades that push large volumes of heat and is designed specifically for large rooms. As air flow velocity in a pipe increases the equivalent pipe length for a pipe fitting also increases.

Most people size the fan to the room dimensions correctly but fail to factor into their calculations the length of duct run and elbows. If you are still unsure about the effectiveness of stove fans and thinking the price of them can be quite an investment, we are very pleased to introduce a great little starter fan. It has a retro design reminiscent of the first fans to market from the big brands such as Caframo or Valiant nearly a decade ago. Despite their revisions over the years the retro design of My Stove Fan will in no way affect the efficacy of its main purpose, which is to circulate the hot air around your room. The Glasshopper by Warpfive is powered by a miniature Stirling engine built in its base. Skipping the very technical aspects, this fan starts to operate at 70°c, and its operates until 300°C. As with all Stirling engine fans it’s a pleasure to watch this beautiful invention at work.
