Function and application

Due to its two coupled pressure chambers, the pressure booster type DPA−... func
tions as a double piston compressor. A control valve conducts the pressure, which
is applied constantly at connection 1, alternately into one compression chamber
then into the other. These generate a high pressure up to double the value of the
input pressure. The adjusting knob 5 can be used for modifying the pressure
increase.
The pressure booster type DPA−... has been designed for increasing the pressure in
compressed air lines. Long running times will lead to shorter idling times due to
the seal wear.
