If the central air-handling system, which provides primary air, does not remain in
continuous operation, a non-return damper on-site should be installed. This pre-
vents the sucked-in room air from being pushed backwards into the sewage sys-
tem when the air-handling unit is switched off. The low filter class of the
HyCassette-Geko and the mixing of air from different zones oppose the hygienic
requirements. Furthermore, depending on the operating point, there is a risk of
condensation on the external sides of the on-site ductwork.

With the HyCassette-Geko, such a primary air supply is possible on one unit
