4.4.3 Air volume flow primary air
The air volume flow of the supplied primary air depends on the nominal volume
flow rate of the HyCassette-Geko (see Tab. 2-9on page 20) and on the pressure
drop of the primary air connection (see Fig. 4-9 and Fig. 4-10).

NOTE!
To keep the air volume flow as steady as possible it is highly recommended to
use a flow rate controller in an on-site primary air duct.
