Double fan

Two fans guarantee continuous air renovation/pressurization, it is possible to do maintaining one of them while the other is in service.

Reduced noise

The new HVAC units have very balanced components, vibration absorbers and noise reducers. All of this joint with his strong structure do that the noise level is reduced.

Easy maintenance

The CLB series is fully accessible thanks to his structure with covers, his design is thinking to facilitate the maintenance and repair.
