It features a serviceable internal filter to prevent debris and contaminants from damaging other air system accessories. It opens to supply air to the suspension at 75 PSI and closes to isolate the brakes at 70 PSI, ensuring you maintain enough pressure for safe stopping. It's commonly replaced when it fails to hold pressure, leaks, or when the internal filter becomes clogged, which can cause suspension or brake system malfunctions.
