HVAC – assembly of the heating, ventilation and air conditioning technology

Fastening the interior air conditioning

The HVAC unit is located behind the dashboard of the vehicle and must be precisely attached to it. A screw connection of the two components is subject to tolerances and is therefore unfavorable. Tolerances can lead to noticeable vibrations on the dashboard. These vibrations can in turn generate disruptive noises in the vehicle interior. Further screw points exist between the end wall and the firewall – the additional support not only ensures better fastening, but also eliminates unwanted vibrations.

By using WITOLs, the HVAC unit is firmly connected to the dashboard without stress. The use of WITOLs compensates for the tolerances between the HVAC unit and the dashboard, and at the same time prevents the occurrence of vibrations.

These WITOLs are used with the HVAC unit
