Good air for people

Good air for people

Ventilation and air handling units for meeting, sales or cultural venues have an important task: to replace stale indoor air with fresh outdoor air. Thus, they create comfortable and healthy environmental conditions for people. Fresh air also increases people’s performance in office buildings, educational institutions and sports facilities; a high CO2 content in the air lowers the ability to concentrate.
