Troubleshooting the Ingersoll Rand P185: Air Flow System Issues
If your Ingersoll Rand portable compressor isn’t performing the way it should, the air flow system is a good place to start. This guide covers common issues and solutions for models P185A-SJD, P185A-WJD, XP175A-SJD, and XP175A-WJD—helping you quickly identify and fix airflow-related problems without the need for a service call.
1. Air Cleaner Life Is Too Short
Issue: You’re blowing through air cleaners faster than you should, which can get expensive and reduce performance.
Cause: This is typically caused by a defective service indicator. If the indicator isn't accurately showing when it's time to change the air cleaner, you could be replacing it unnecessarily. Or worse, running the machine with a clogged one.
Solution: Replace the faulty service indicator. A working indicator helps extend the life of your air cleaner and protects your system from ingesting debris.

2. Erratic Operation of the Blowdown Valve
Issue: If your blowdown valve is acting up, you might notice inconsistent pressure release after shutdown or startup.
Causes:
- Defective blowdown valve diaphragm
- Dirty or clogged blowdown valve
Solution: First, inspect the diaphragm for cracks or signs of wear. If damaged, replace it immediately. If the diaphragm looks okay, the valve may just need a thorough cleaning—or full replacement if gunk buildup has taken a toll.
