Maximum operating pressure with G4 or F7 filtration
CONTROLS
Ventilation
Maximum operating pressure dependent on air flow rate. Take away approximately 20 Pa if there is a hot water coil on 50CJ.
The operating point can be adjusted directly via a built-in voltage regulator. Hence all the air flow/operating pressure combinations are possible, with the values in the table above as the
maximum values.
