Precision Manufacturing & Assembly
The Turbo Kings AD-IP (SAPO) Air Dryer #65612 is newly manufactured to OEM Bendix AD-IP specifications and engineered for modern air-system reliability. Each unit is pressure-tested to 150 PSI, ensuring total air-tight integrity, stable purge-valve performance, and consistent moisture-removal efficiency under full load.
The AD-IP (Short After Purge Orifice — SAPO) design provides faster purge recovery and improved pressure balance compared to standard AD-9 units. This design helps prevent moisture back-feed into the service tanks, especially in high-humidity or cold-weather applications.
Every Turbo Kings air dryer receives BRV high-temperature O-rings for advanced sealing durability and HP-870 synthetic grease to protect internal pistons, check-valves, and purge mechanisms from corrosion or galling. Each unit is purged, neutralized, and fully moisture-free before sealing — ready to install straight out of the box.
What Makes Turbo Kings Air Dryers Different
Turbo Kings AD-series dryers are locally assembled, batch-tested, and serialized for traceability — not mass-produced imports. Each dryer undergoes real-world testing for purge timing, heater operation, and governor response before leaving the shop.
SAPO Short After Purge Design — Optimized for faster purge recovery and moisture evacuation
BRV High-Temp O-Rings — Engineered for prolonged heat and vibration resistance
HP-870 Synthetic Grease — High-temperature lubricant for smooth, low-friction operation
Full 150 PSI Pressure Testing — Confirms air-integrity, purge control, and leak-free sealing
Cleaned & Neutralized Internals — Moisture-free and corrosion-resistant
Built by Turbo Kings — Precision-assembled locally for consistent performance
Why Fleets and Owner-Operators Trust Turbo Kings
Fleet operators depend on AD-IP air dryers to maintain clean, dry air through braking, suspension, and emission-control circuits. Turbo Kings enhances this proven Bendix design with upgraded sealing materials, controlled lubrication, and final bench testing that simulates real-pressure duty cycles between 135 and 150 PSI.
Each 65612 unit is built to handle the toughest duty cycles — from long-haul applications to regional delivery trucks — ensuring reliable purge performance and reduced compressor strain. With consistent moisture removal and fast re-charge times, drivers experience smoother braking, fewer freeze-ups, and longer component life throughout the air system.
Delivered pre-lubed, pressure-validated, and moisture-sealed, the Turbo Kings AD-IP (SAPO) arrives installation-ready — no adjustments, no pre-prep, and no compromise on performance.
