Air Filtration for Buildings

Bag filters

Ideal business climate for employees and customers.

The layout of the HVAC equipment has to be as individual and flexible, as the building with its dimensioning and architecture, where this equipment is installed. Shopping malls set a good example and make it clear that different requirements and specifications meet in this place: customers should feel comfortable and at ease, stay in the mall as long as possible while making their purchases. The goods should not be covered with a dust layer.

Advantages
