Compressor Pressure Drops: Causes & Fixes
Not sure if your system is struggling to build pressure at all? Check out our troubleshooting guide for compressors that won't build pressure.
If you run a rotary stationary system or a larger portable setup, sudden or gradual pressure drops can be more than frustrating. They can impact production quality, tool performance, and operating costs. Luckily, most causes can be identified and corrected with a bit of digging.
1. Leaks in the Air System
Leaks are the number one cause of unexpected pressure drops. Even small leaks in fittings, hoses, or joints can sap pressure across your entire system. Conduct regular leak checks and repair problem areas immediately.
2. Undersized or Poorly Designed Piping
Long piping runs with small diameters or too many sharp bends increase friction and reduce pressure. Upgrading to larger or properly sized piping and simplifying layout can help maintain consistent pressure throughout your system.
3. Blocked or Dirty Filters
Clogged air filters add resistance and cause drops downstream. Check and replace filters on schedule to keep airflow steady and clean.
4. Failing or Undersized Air Dryers
If your dryer isn’t sized properly or isn’t working effectively, it can cause pressure restrictions. Make sure your dryer matches your system capacity and inspect it regularly for proper performance.
5. Excessive Demand Surges
If multiple high-demand tools run simultaneously, your system may experience short-term pressure drops. Adding storage tanks or staggering tool use can help balance demand.
Key Takeaway
Solving pressure drops starts with regular inspections and proactive maintenance. Addressing leaks, optimizing piping, and keeping filters and dryers in top shape can restore and maintain consistent air pressure.
