Ventilators

Ventilators are a cost effective way of extracting hot polluted air from your building indoor environment and introducing fresh air to replace it. The system is human and environmentally friendly and requires no electricity to operate. Ventilators are activated by natural convection which is also assisted by the wind. Increasingly this type of industrial ventilation is gaining acceptance in the hospitality industry replacing energy consuming extraction systems.

The roof a building contains hot air due to heating caused by the sun and production processes. The internal hotel 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 hotel 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 hotel patrons and workers plus improves the indoor air quality. The system also assists in maintaining a consistent ambient indoor temperature. Ventilators can also be wall mounted.

What you need to know:

Prevailing atmospheric conditions will vary ventilation rates
Eliminates dust penetration and a down-draught into the building to ensure a cleaner and healthier working environment.
Reduces heat build-up in immediately under the hotel roof and reduces heat radiation from roof into the hotel interior
Reduces the workload of the air-conditioning system
Positive extraction removes heat, fumes, steam, dust and bad odours
Improves productivity by creating a better working environment by removing hot polluted air
Improves indoor air quality
Requires no maintenance
Silent operation
Make sure installation is done correctly to prevent gaps and water penetration
Make sure the system is bird proof
Removes moisture which is known to deteriorate structures and cause mould to grow in roof rafters and attic spaces
The deployment must be part of the overall design, working in balance with other ventilation features.
