Hankison RDMK1 Kit

Optimizing your compressed air system requires rigorous preventative maintenance, and the Hankison RDMK1 maintenance kit is the industry standard for servicing 5-10 CFM refrigerated air dryers. Designed for Hankison PR5, PR5A, PR10, and PR10A units, as well as the 8000 and 9000 series, this kit is the essential refrigerated dryer service kit for professional contractors. It contains a high-efficiency separator element, a reliable automatic drain mechanism, and crucial sealing o-rings to prevent pressure drops and moisture carryover. By replacing the compressed air filter element and servicing the 115V or 230V solenoid drain regularly, you ensure a consistent pressure dew point and protect downstream pneumatic tools from corrosion. The RDMK1 is a direct OEM equivalent replacement for part numbers 05-4170-01, 05.4170-07, and K-342, offering seamless integration into your existing air treatment system without requiring modifications to the condensate management assembly.

Key Benefits for Technicians:

• Broad Compatibility: Serves as a direct drop-in for Hankison 05.4170-01, 05.4170-02, and 21-006 cross-references.
• Complete Rebuild Components: Includes the separator, insulation set, fasteners, and a replacement drain tube for a thorough overhaul.
• Enhanced Efficiency: Restores optimal flow for 5-10 CFM compressed air dryers, reducing energy consumption by minimizing differential pressure.
• Moisture Control: Prevents liquid water bypass, safeguarding sensitive HVACR controls and industrial machinery.

Common Service Questions:
