External effects can cause the fan parts to wear out before their service life. For this reason, the fan body, parts and motor should be manufactured extremely durable. Cvsair kitchen fans are fabricated from galvanized steel sheet to protect fans from external effects. Zinc layer prevents chemical reactions on the fan surface. The fan motor is positioned outside the body therefore outside the air flow. All parts of the device are manufactured to be heat resistant to be able to work at 120°C continuously. Air flow can be controlled up and down thanks to the radial propellers. Fans are suitable to work with speed controller and frequency inverters.

The protection class of the fan is IP55 ( Ingress Protection ). The first figure in the protection class represents the protection against solid particles and ranks degree of protection. The second figure in the protection class represents the protection against moisture. With IP55 protection class, Cvsair Kitchen fans have protection against dust and low – pressure jets.
