The Pressure Booster DPA is a high-efficiency twin-piston pressure intensifier specifically designed for air compression applications. It amplifies the input air pressure, doubling it to provide a higher output pressure (p2) from the supplied input pressure (p1). Featuring an integrated check valve system, the booster ensures reliable and automatic pressure build-up on the secondary side to meet demanding air pressure requirements. It operates through a pneumatic directional control valve that automatically reverses piston movement upon reaching stroke limits, enabling continuous pressure buildup without manual intervention. The output pressure can be precisely adjusted using the manually operated pressure regulator; alternatively, models without regulators provide a fixed doubled output pressure. Its compact design and long service life make the DPA pressure booster an ideal solution for intermittent high-pressure air supply in industrial settings. It is available as combined units with air pressure reservoirs and includes options such as pressure sensing and regulator lock to prevent unauthorized adjustments. However, it is recommended strictly for occasional pressure boost tasks and not as a compressor substitute, due to potential excessive seal and piston wear under continuous operation. The use of a pressure gauge is recommended to monitor output pressure accurately, ensuring operational efficiency and safety.

No, the DPA pressure booster is designed for occasional compressed air boosting. Continuous operation significantly increases seal and piston wear and is not recommended.
The output pressure can be manually adjusted using the pressure regulator on models equipped with one. Models without a regulator provide a fixed output pressure that is always double the input pressure.
A pressure gauge is strongly recommended but not necessarily included. It helps ensure the output pressure (p2) is accurately monitored for safe and efficient operation.
Certain models of the DPA booster include a regulator lock (LRVS) that secures the pressure setting from unauthorized changes.
Yes, the booster automatically ceases operation to save energy once the set output pressure is attained, and restarts when pressure drops below the threshold.

Characteristics
At a glance
The pressure booster is a twin-piston pressure intensifier used only for compressing air. When the DPA is pressurised with compressed air, integrated check valves automatically ensure the pressure on the secondary side is 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 pressure boosters without a pressure regulator, the output pressure is always double the input pressure. The air supply to both drive pistons is controlled by a pneumatic directional control valve that reverses automatically when the stroke end position has been reached. The pressure booster starts up automatically when the input pressure is applied and the desired output pressure has not yet been reached. When the set output pressure is reached, the pressure booster stops operating to save energy, but restarts automatically when the output pressure drops again.

Note: Pressure boosters are used for the occasional drawing-off of pressurised compressed air. Pressure boosters are not suitable as a substitute for a compressor, as wear on the seals and drive piston increases significantly when used continuously without breaks.
Note: A pressure gauge is strongly recommended to check the output pressure p2, as the required output pressure p2 must be set. The regulator setting of the DPA-63/100 can be secured against unauthorised adjustment using the regulator lock LRVS.
