Komatsu PC200-7 Excavator AC Compressor 20Y-979-6121 10S15C 24V

• Mature 10S15C Piston Compression Technology: Adopts industry-proven ten-piston circulating compression structure, with uniform pressure output and low internal leakage rate. It solves the problems of weak cooling and pressure attenuation of ordinary compressors after long-term use.
• High-Precision CNC Machining Process: Core components including compressor housing, crankshaft and piston are processed by CNC precision machine tools with ultra-tight tolerance control, ensuring excellent assembly accuracy and airtightness.
• Intelligent 24V Electromagnetic Control Technology: The high-sensitivity electromagnetic clutch system realizes instantaneous start-stop linkage with the vehicle AC switch, with accurate control and low power consumption, effectively reducing idle loss.
• Professional PAG 46 Lubrication Matching Technology: Optimized internal oil circuit structure, perfectly adapted to PAG 46 lubricating oil viscosity characteristics. It forms a stable protective oil film on friction parts to reduce wear and extend component service life.
• Built-In Overpressure Protection Technology: Equipped with integrated pressure relief structure, which automatically releases pressure when the system is overloaded to avoid compressor burnout and pipeline burst caused by excessive pressure.
• Full Sealing & Anti-Corrosion Process: Adopts integral glue filling sealing and surface epoxy anti-corrosion coating technology to isolate external moisture, dust and oil erosion, improving overall durability.

• OEM-Grade Quality with Cost-Effective Pricing: Strictly manufactured according to OEM technical standards, with consistent cooling performance, airtightness and durability as genuine parts. It delivers original-equipment quality at competitive aftermarket prices, helping B2B buyers reduce overall procurement costs.
• Ultra-High Operational Stability: Optimized piston compression structure and professional oil circuit design effectively avoid common failures such as refrigerant leakage, weak cooling and clutch slippage, with extremely low daily failure rate.
• Excellent Harsh Condition Adaptability: With IP-level dustproof and waterproof performance, high-temperature resistance and vibration resistance, it maintains stable working efficiency without attenuation even after long-hour continuous operation.
• Wide Model Compatibility: Universally compatible with multiple mainstream Komatsu 7-series excavator models, covering PC130-7, PC200-7, PC210-7K and PC220-7, reducing customer inventory pressure and enriched product applicability.
• Time & Labor Saving Installation: Complete bolt-on direct-fit design requires no modification or debugging, greatly improving maintenance efficiency and reducing on-site construction costs.
• Adequate Spot Inventory: Massive in-stock supply supports small-batch sample testing and large-volume wholesale orders with fast global delivery.

We implement standardized industrial production and full-process quality control for every excavator AC compressor to ensure consistent OEM-level quality:

1. Premium Raw Material Screening: Select high-purity aviation-grade aluminum alloy housing, wear-resistant piston components and high-toughness crankshaft, eliminating inferior raw materials from the source.
2. CNC Precision Machining: Core structural parts are processed by digital precision machine tools to strictly control assembly tolerance, ensuring OEM-level fitting accuracy.
3. Precision Assembly & Lubrication: Complete assembly of pistons, bearings, clutch components and internal oil circuits, and inject standard PAG 46 lubricating oil according to factory specifications.
4. Vacuum Leakage & Pressure Testing: Conduct high-precision vacuum pumping and high-pressure holding tests to ensure zero refrigerant leakage in the whole machine.
5. Anti-Corrosion Sealing Treatment: Adopt high-temperature curing epoxy coating and integral sealing process to enhance dustproof, waterproof and anti-oxidation capabilities.
6. Full-Function Performance Calibration: Test and calibrate clutch sensitivity, operating pressure and refrigeration cycle to ensure stable and consistent overall performance.
7. Shockproof Professional Packaging: Adopt foam buffer + thick carton outer packaging to prevent collision damage during long-distance international transportation.
