The pneumatic compressor DPA is used for cost-effective pressure amplification. It doubles the input pressure and is driven exclusively by compressed air without additional power. The high pressure achieved in this way ensures higher motive forces in the connected pneumatic aggregates. An automatic delivery stop takes place once the set pressure level is reached. The DPA is characterised by fast and easy handling, which is of particular advantage during installation: only the compressed-air supply has to be connected. The absence of wearing parts makes the DPA truly maintenance-free.
