What to do if my General Air Products Dry Air Pac DAP500 Air Compressor has excessive pressure drop?
- MMatthew BrownAug 13, 2025
Excessive pressure drop in your General Air Products Air Compressor may be due to several factors. It could be caused by low inlet pressure, so try lowering the flow rate to the system. Alternatively, a switching valve failure could be the reason; check the tower-operating sequence to identify which valves are operating correctly. Desiccant breakdown can also cause this issue, requiring you to change the desiccant. Clogged filters are another potential cause, so replace the filter elements. Lastly, ensure that no valves are accidentally shut; if so, open them.
