Why is air delivery dropping off in my Ingersoll-Rand SS5N5 Air Compressor?
- FFrances StevensAug 20, 2025
A drop in air delivery from your Ingersoll-Rand Air Compressor can stem from several issues. Check for clogged or dirty inlet and discharge line filters and clean or replace them as needed. Inspect air discharge piping for leaks. Also, lubricant with too high viscosity can cause this, so drain and refill with the proper lubricant. Other potential causes include leaky, broken, carbonized, or loose compressor valves (inspect, clean, or replace, and consider installing a valve kit), damaged or worn piston rings (install a ring kit), piston rings not seated properly (adjust them), scratched, worn or scored cylinders or pistons (repair or replace), or a defective safety/relief valve (replace it).
