Technical Description
Air Amplifiers
Revision 11.2011
11
Control air is supplied externally for air amplifiers with a port X. It is branched off
from the drive compressed air (upstream of pressure reduction), being charged
through pipes to port X. A directional control valve in the control pipe can be used to
switch the air amplifier on or off.
Example:
Drive compartment II
= 4 bars
+ compression
compartment I
= 4 bars
Compression
compartment II
= 8 bars
