Precision Remanufacturing & Factory-Grade Performance
The Turbo Kings WABCO System Saver 1200 Plus “4324801440RX” Air Dryer is a precision-engineered rebuild designed to match or exceed OEM reliability. Each unit is fully disassembled, cleaned, and tested to restore complete functionality of the integrated governor, purge valve, and coalescing cartridge interface.
The System Saver 1200 Plus represents WABCO’s highest-tier air dryer, built for modern engines requiring maximum moisture and oil vapor separation. Its internal flow channels and coalescing element maintain optimal downstream air purity, protecting valves, modulators, and emission systems from contamination.
What Makes a Turbo Kings Rebuild Different
Turbo Kings rebuilds go far beyond cosmetic refurbishment. Every air dryer core is meticulously overhauled through a controlled process designed to restore mechanical and pneumatic integrity.
Hot Alkaline Cleaning Process: Each housing undergoes a high-temperature alkaline bath to dissolve oil film, rust, and carbon residue.
OEM-Gauge Sealing Components: High-temp BRV O-rings and Viton gaskets are replaced throughout all sealing surfaces.
Reconditioned Purge Valve Assembly: Valves are disassembled, cleaned, and fitted with new springs and diaphragms.
12V Heating Element Tested for Draw & Continuity: Ensures freeze protection and purge reliability in subzero conditions.
Governor Assembly Calibrated to OEM Specs: Rebuilt and bench-tested for accurate cut-in/cut-out regulation (typically 120–135 PSI).
Pressure-Tested to 150 PSI: Each rebuilt dryer is validated for zero external leaks and full purge function.
Premium Oil Coalescing Cartridge Compatibility: Each unit accepts WABCO’s 1200 Series coalescing filter to capture submicron oil vapor.
After assembly, every dryer is subjected to a two-stage validation — first for static pressure retention, then for dynamic purge sequencing to simulate real-world compressor cycling.
Why Fleets and Owner-Operators Trust Turbo Kings
Fleet-tested reliability and precision rebuilding define every Turbo Kings product. The 4324801440RX is not simply restored — it’s optimized. Our rebuilds consistently outperform off-brand aftermarket units through tighter valve tolerances and controlled purge behavior that reduces air compressor wear and moisture intrusion.
Each dryer is serialized, date-coded, and bench-certified before packaging. Your unit arrives pre-lubed, moisture-sealed, and ready for direct installation — no additional setup or recalibration required.
Turbo Kings rebuilds are trusted by heavy-duty fleets, dealerships, and independent operators across the U.S. for consistent pressure regulation, quick recharge times, and long-term reliability under daily commercial use.
