It acts as a primary filter to remove moisture and contaminants like dirt and oil from the air supply before it reaches the rotating seals and tires. A clogged filter can starve the system of air, leading to deflated tires, so fleet maintenance schedules call for its regular replacement to keep correct tire pressure on trailers.
