Keeping Things Fresh
Ventilators are a cost effective way of extracting hot polluted air from within the factory working environment and introducing fresh air to replace it. The system is human and environmentally friendly and requires no electricity to operate. Factory ventilators are activated by natural convection which is also assisted by the wind. The roof of a building contains hot air due to heating caused by the sun and production processes.
The internal factory areas generally contain air that is much cooler. To allow natural convection to occur, provision is made for a vent at the top of the factory roof cavity. This allows the hot air to rise out of the roof cavity and escape. The system extracts heat and induces currents of fresh air producing a substantial cooling effect on factory workers and improves the indoor air quality. The system also assists in maintaining a consistent ambient indoor temperature. Ventilators can also be wall mounted.
