Exhaust Ventilators

The Roofvent exhaust ventilator, manufactured in India, helps to speed and facilitate air exhaust by limiting back pressure on the fan and motor. On a relatively calm day, this removes hot, humid air from roof spaces at an exhaust rate equivalent to about four domestic wind turbines. The exhaust rate of all power vents should only be compared under the conditions of the Indian standard. By removing, hot humid air from roof spaces, enabling it to be replaced by cool, fresh air, the roof space temperature in a home is prevented from reaching extreme levels during summer. This reduces the heat load on insulation and ceiling thereby providing a more comfortable home with room temperatures reduced by up to 5?C during the peak of summer. The Roofvent exhaust ventilator also improves the performance and lowers the running cost of ducting air conditioning by reducing the level of heat exchange occurring between air in the attic and that carried in the ducting. The operation of the Roofvent exhaust ventilator is controlled through a thermostat, which can be either a wall mount type or attic type. The thermostat can be set at a level, which activates Roofvent exhaust during mid morning, before the roof space has a chance to heat up. One Roofvent Exhaust Ventilator can provide adequate ventilation for a 20 sq.mtr (180?) home. No electrician required if a power point is available within roof cavity.
