Direct Drive Roof Exhaust Fan

I’ve had this vent cover for about a year and it continues to be a great product. With this, I can leave the Fan-Tastic fan in open but not running and not worry about a rain storm. Makes a big difference in letting hot air escape from the top of the camper. One of our most popular roof mounted fan accessories is our exhaust fan safety handle. These unique handles provide a safer way to lift and close the inner fan and duct work without causing any damage to the fan bowl or seals. By providing easier access, they help prevent maintenance issues during cleaning, servicing, and fire inspection. Also, be sure to lock and tag the disconnect switch or breaker to prevent an accidental power up. The disconnect switch is located on the exterior of upblast fans and in the interior of downblast fans. On downblast direct drive fans, the disconnect function is built into the speed controller.

Electrically powered fans typically have a thermostat that turns the fan on and off as temperatures inside the attic rise and fall in response to air movement. Attics are vented using the natural circulation that occurs when hot air rises. Vents in the soffit beneath the eaves at the bottom of the attic draw in cool outside air while gable or ridge vents at the peak of the attic allow heated air to exit. In hot climates, a power vent fan is often mounted behind a gable vent or cut into the roof near the peak to assist this process by forcibly expelling additional hot air from the attic. This 1,000 CFM Galvanized Steel Electric Fan can pump out enough hot and humid air to keep attics of up to 1,600 square feet cool. It’s an electric vent; however, this fan keeps energy costs down via its thermostat, which turns on the fan only when the heat in the attic reaches a certain temperature.

Solar attic fans are ideal for any homeowner looking to keep the world green and their home cool and healthier. Roof ventilators provide cost-effective, general purpose ventilation of commercial buildings, as well as a large variety of industrial applications. The SD Square In-Line Centrifugal Fans are designed to provide efficient air movement in ducted or non-ducted ventilation systems. Designed for easy positioning and quick installation, the versatile Square In-Line can be located inside equipment rooms, in ceiling spaces or as parts for O.E.M. equipment. SB Belt Drive Square In-Line Fans The SB Square In-Line Centrifugal Fans are designed to provide efficient air movement in ducted or non-ducted ventilation systems. These upblast power roof ventilators are designed for long life, low maintenance and all-weather performance. Each unit features a forward-curved wheel and heavy gauge galvanized steel housing. HGTT-V series of mounted axial flow fans, with vertical air discharge configuration. Is made from a casing formed from rolled sheet steel welded on the base with a corrosion resistant hot dipped galvanized finished. This fan has a high grade die-cast aluminium blades locked within a pressed sheet steel hub.

Constructed with six extruded aluminum airfoil blades and mounted to a cast aluminum hub. Prior to the EC motors , complex control strategies and additional external electrical components, such as VFD’s , were employed to vary the volume of air. An EC motor is approximately 80 percent efficient vs a traditional PSC motor which is around 60 percent efficient. These are the wires leading from the fan down the side of the van and eventually to the fuse bar in the electrical box. A couple weeks later, we finished our ceiling panels so we were able to officially attach the garnish ring. All we had to do was slide it in and drill in the screws using the power drill. If you’re lucky enough to have an RV equipped with an RV roof rack, you have a great place to store extra equipment while you are traveling. Luggage, bikes, your mother-in-law (!), all kinds of things can be transported on your RV’s roof if you have the right equipment. Like your RV roof, your RV’s air conditioner requires some yearly maintenance. It’s important to keep the air conditioner clean so that it has a long and “cool” life.

Their length makes them more efficient than vents that cover one small area, while the design keeps them hidden, making them a popular option in newer homes. A ridge vent, a variation of a hip vent, is suitable for pyramid-shaped hip-style roofs. Exhaust vents allow the hot air to escape, preventing the buildup of heat. Unlike a dryer vent that vents through a wall, most exhaust vents exit through the roof. An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents. This will help to avoid premature damage to the shingles or mold building up in moist, hot attics. If you have a partially finished attic but still want help controlling excessive heat, the AC Infinity AIRTITAN T7 fan may be for you. This model is small enough to fit over an air conditioning and heating vent but can also be vented outside, running at a programmed temperature range.

A roof-mounted is close to your vent hole near the rooftop while the other versions are installed in the attic. This product has a CFM of 1960 and a brushless motor that is of high efficiency to offer to prevent moisture accumulation and keep a quiet environment. Operating this product is very easy since it has an in-built thermostat with a unit which is automatically functions and is adjustable too.

AQD is a direct drive unit available in 8 sizes from 12 to 48 inches. Performance ranges from 343 to 19,500 CFM with static pressures from 0 to 0.75 inches. I decided on the Maxxair because it made the most sense for my setup and my budget.

I’ve read that adding a vent fan to the gable with ridge vent is bad b/c it may reverse the natural flow of hot air plus draw in rain. I have ranch house that has ridge vent, soffit vents and two gables. I added a attic fan, 1500cfm onto the gable, but i have the airflow coming in from the outside instead of pushing air out. This will allow the outside cooler air to enter the attic and the natural flow of hot air will rise out of the ridge vents.

This is a home that I just purchased–its summertime and I am getting ready to move in. Problem I have been working in this room painting, it is unbelievably hot and the attic from inside has no access—is not available from the existing house. I need to cool my attic first of all –no ridge vent and can I install say ridge vent or wind powered turbines from the outside only? In a multi-family building, a downblast fan is mainly used for bathroom and dryer ventilation, whereas an upblast fan is primarily used for kitchen exhaust. Since dryers, kitchen hoods, and bathroom fans are usually not running at the same time, single speed PSC powered fans are not the most efficient option. These exhaust systems only operate a fraction of each day, so having the central exhaust systems running at 100% for 24/hours per day wastes energy.
