Roof hot air extractors.

We supply roof extractor fans to several industries where they solve the problem of ventilation removal of hot spots etc. The roof or rooftop exhaust fan is the most efficient way to rid a building or facility of overheated air issues. A roof ventilator is perhaps the most crucial step in keeping your home cool. The roof top extractor attracts fresh air from every side and direction of roof and channelizes it move towards the center.

This pressure exertion pulls out the stale and bad odored air from the building. These fans sit in a gable end or in the sloping part of the roof. In turn this superheated air heats both the structure of the building and the cooler air below. If you can t move heat out of your roof it won t go anywhere.

From up on the roof use a jigsaw or reciprocating saw to cut a 4 in. Using extractor fans to remove hot air from roof spaces warm air rises because it is lighter than cool air. 300 to 1200 mm. An attic venting fan only works on the air in the roof space but in many cases it can help cool the entire home.

The sun heats the air in the roof space to over 60c 140f. 1300 to 60000 cmh. In commercial buildings such as factories and workshops the warm air generated by machinery and workers rises into the roof space where it is trapped. And don t settle for a whirlybird ventilator as they only help extract minimal amounts of air.

A low profile static roof ventilator that allows nominal ventilation of hot or moist air from the roof space without the need of wind or power assistance. Some models feature a hinged hood to ease access to motor and drives for maintenance. Start in the attic and drill a hole through the roof in the desired vent location. We can t stress this enough.

Leave the drill bit sticking through the roof so you can find the hole. Try to keep it close to the fan location. Roof ventilators are designed to help exhaust contaminated air from kitchen range hoods up and away from the roof. The second step you need to take is to install a number of vents into your ceiling to allow the air to be extracted out of your upstairs rooms and through the roof space cavity by your new solar roof ventilation unit.

Simply having eave vents or roof vents isn t enough to cool your roof. As the air only has one path to escape from the room the warm air will be drawn to the top of the ceiling where you roof vent is placed and then from there through the roof space and finally drawn out through the fan. Even on scorching summer days the air outside your house is nowhere near as hot as the air trapped inside the attic. Since hot air rises to the ceiling or the highest point of a structure it makes sense that having exhaust fans mounted on the roof will work best.
