Receiver Drier
Volvo

The receiver drier is a vital part of the air braking system, designed to remove moisture and contaminants from compressed air before it reaches the brake valves and actuators. This component houses a desiccant medium that adsorbs humidity, helping prevent rust, corrosion, and ice formation inside the system, which can lead to brake lag or failure. In demanding Volvo applications, keeping the air clean and dry is essential for consistent brake response, predictable clutch and suspension performance, and long service life of downstream valves. A well-maintained drier also supports accurate air-pressure regulation by preserving the integrity of the dryer’s seals and purge circuit. Installation typically requires ensuring proper fit with the cold- or hot- side piping and compatibility with the vehicle’s air-reservoir pressure range. Regular replacement eliminates desiccant saturation that reduces drying efficiency, especially in humid climates or heavy-duty duty cycles where moisture pickup is higher. When you choose this part, you’re prioritizing reliability, predictable braking, and reduced risk of moisture-related faults. Source One Parts Center.
