as from January 2023

Suction module for adapting an HR or XR+ air heater for outdoor air intake.
This module allows fresh outdoor air to be heated and introduced into the space. Using the damper section (top/rear or bottom/rear), you can adjust the ratio of indoor and outdoor air. The unit must be mounted directly against the wall; adding an additional duct section is not possible. Highly suitable for spaces where large amounts of air are extracted (welding, painting, woodworking, etc.).
