Trailer Air Brake Filtration

Phillips Industries says its new Air-Defense System, a trailer brake in-line filtration system with Quick-Change cartridge, traps debris before it can cause dangerous, expensive, and time-consuming repairs.

When it’s full, a red indicator pops out giving a quick visual notification to a technician or operator that it needs to be replaced. Replacement of the cartridge is said to be accomplished in minutes without added downtime to the vehicle.

The patent-pending system can be used on both service and emergency lines.
