Hankison RDMK4 Kit

The Hankison RDMK4 Maintenance Kit is a comprehensive service solution engineered for refrigerated air dryers operating within the 50-100 CFM range. Designed to ensure peak moisture separation and system reliability, this factory-spec kit is a direct replacement for HKN-RDMK4 and is compatible with Hankison PR50, 8070, 80100, VL70, and VL100 series dryers. It is also an equivalent service match for specific Devair and Palatek models, including the DRD75 and PRD100.

Professional maintenance with the Hankison RDMK4 prevents downstream contamination by replacing critical wear components that degrade over time. Each kit includes a high-efficiency refrigerant dryer separator element, an automatic drain mechanism, and a complete set of seals and O-rings. By refreshing the compressed air dryer service parts every 12 months or as indicated by the service reminder decal, technicians can maintain the pressure dew point integrity and prevent liquid carryover into the air lines. This Hankison air dryer repair kit provides the technical components needed to restore factory-level performance and protect pneumatic equipment from moisture-related failures.

• Extended System Life: Regular installation of the Hankison RDMK4 elements reduces the load on the compressor and prevents internal corrosion.
• Optimized Separation: Features a premium separator element designed to effectively strip moisture from high-velocity 50-100 CFM airflows.
• Verified Compatibility: Replaces HKN-RDMK4 and fits multiple OEM brands including SPX Flow, Devair, and Palatek.
• Reduced Downtime: All-in-one kit simplifies the 1,000-hour or annual service interval for field technicians.
