Donaldson P951413 Air Dryer Spin-On Coalescing Filter

The Donaldson P951413 is a spin-on coalescing air dryer filter designed for heavy-duty truck and commercial vehicle compressed air brake systems. This advanced filtration cartridge removes both moisture and oil aerosols from compressed air before they can enter air tanks, valves, and brake components, helping prevent corrosion, freeze-up, and premature component failure.

Key Features:

• Coalescing technology removes water vapor and oil aerosols from compressed air
• Spin-on design for quick and convenient cartridge replacement
• 5.51-inch outer diameter with M39 x 1.5 thread size
• 6.50-inch overall length for effective filtration capacity
• Protects critical air brake components including valves, chambers, and control systems
• Compatible with modern automated manual transmissions and electronic control systems that require clean air
• Cross-references to DAF 1506635, Baldwin BA5379, Bendix 5004814PG, and other OEM part numbers

Air dryers are essential safety components in heavy-duty truck air brake systems. The P951413 coalescing filter cartridge provides superior protection compared to standard filters by capturing oil aerosols that can damage sensitive pneumatic components. This is especially important for newer vehicles with automated transmissions, electronic stability control, and other systems that depend on clean compressed air for reliable operation.
