Air boosters

Pressure booster DPA

The pressure booster DPA is a twin-piston pressure intensifier used to compress air. When the compressed air booster DPA is pressurised with compressed air, secondary pressure is automatically built up. The output pressure p2 can increase to up to twice the value of the input pressure p1. The required output pressure is set using a manually operated pressure regulator. In the case of Festo pressure boosters without a pressure regulator, the output pressure is always double the input pressure. A special feature of the Festo compressed air booster DPA is the sensing option: when equipped with an external sensor and an adding counter, the DPA can detect the strokes of the drive piston, thus enabling the service life to be monitored. Pressure boosters are designed in principle to increase the pressure at low air consumption.
