Phillips Air Defense SystemPhillips’s Air-Defense System is a trailer brake in-line filtration system for both service and emergency lines designed to trap debris before it can lead to expensive and time-consuming damage and repairs. The system incorporates the company’s Quick-Change Cartridge that features a bypass mode designed to facilitate airflow at all times and catch debris. When the cartridge is full, a red indicator pops out, giving a quick visual notification that it needs to be replaced.
