Air Dryer Meritor Style R955300
The Air Dryer is a premium, heavy-duty air dryer assembly engineered for commercial vehicles with air brake systems. Its advanced coalescing and desiccant filtration ensures the delivery of dry, clean air to the brake system, preventing corrosion, freezing, and premature brake component wear. This unit is widely applied in Class 7 and 8 trucks and buses from major OEMs such as Volvo, Freightliner, Kenworth, Peterbilt, International, and others. The required external purge tank greatly supports efficient regeneration of the desiccant media.

| Filtration | Utilizes a spin-on desiccant cartridge that incorporates coalescing media to remove oil aerosols, water vapor, and particulates from compressed air, greatly extending system life and protecting downstream air brake components. |
|---|---|
| Regeneration | The “P” series (System Saver 1200P) air dryers use an external purge tank for desiccant regeneration. This design improves moisture removal efficiency and overall air system reliability. |
| Installation | Standard NPT ports fit most North American heavy-duty air systems; mounting hardware and heater harness are included with many kits. |
| Durability | Built from robust materials for maximum corrosion resistance and designed to withstand harsh environmental and operational stresses encountered in trucking and bus fleets. |
| Serviceability | Routine cartridge changes (typically yearly or by mileage intervals) are simple due to the spin-on design. Electric heater protects against freezing in cold climates. |
