Designed for Emergency Smoke Extraction and Commercial Kitchen Hoods

CTH3 smoke extraction roof fans eliminate the harmful effects created when high temperatures and humidity make work and physical effort difficult. They also help extend the life of the structural elements of buildings and warehouses by preventing condensation and humidity. An adequate ventilation system in industrial buildings will considerably reduce cooling and heating expenditure. This type of system easily, continuously and effectively eliminates heat and humidity. The Axair smoke extraction roof fans can be adapted to any type of roof. Their different models offer the perfect solution for each installation, thus optimising its operation.

Operates at Higher Temperatures

CTH3 roof fans offer a maximum continuous operation temperature up to 80ºC and a maximum ambient temperature up to 50ºC. They are specially designed for roof installation and commonly used for smoke extraction, air renewal in buildings and industries and industrial and professional kitchen hoods.

Available Fan Types

Maintenance

It is very important for roof-mounted fans to be easy to clean, as they are very difficult to access. The maintenance of all the extraction system elements is essential and very important to achieve a high standard of cleaning and obtain the required grade of hygiene in each installation, thus preventing the possibility of handling contaminated air particles. Ease in the maintenance and installation of roof equipment leads to important cost savings, which is a factor to be considered.
