How the device works

Distribution of air in the device

For the distribution of the compressed air, the device is composed of the
following units:

•

Blower (40 hPa at 200 l/min )

•

Air outlet (standardized tube connector [M22]) with

ow element and

proportional valve

•

Non-return valve

•

Humidi

er (optional)

•

Oxygen block including 3/2 directional valve and self-locking con-
nection

•

Pressure measuring tube connection (



= 3.5 mm)

•

Control pressure tube connection (



= 4.5 mm)

•

Connection for oxygen sensor (jack 2.5 mm)
