The characteristics illustrated are appli-
cable for the device design with pressu-
re sensor technology for volume flow
constant regulation, supply air filter
quality category F7, extract air filter
quality category G4 and the design with
PTC pre-heater battery in bypass mode.
The SFP values shown take into account
power consumption for both fans for
supply air and extract air as well as the
power consumption of the control unit.
