Komatsu PC200-7 AC compressor, PC200-7 air conditioning compressor, 10S15C excavator compressor, 20Y-979-6121 AC compressor, 24V excavator AC compressor, Komatsu 7-series excavator AC parts, aftermarket excavator air conditioner compressor
Product Core Technology
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.
Product Competitive Advantages
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.
Production Process
We implement standardized industrial production and full-process quality control for every excavator AC compressor to ensure consistent OEM-level quality:
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.
CNC Precision Machining: Core structural parts are processed by digital precision machine tools to strictly control assembly tolerance, ensuring OEM-level fitting accuracy.
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.
Vacuum Leakage & Pressure Testing: Conduct high-precision vacuum pumping and high-pressure holding tests to ensure zero refrigerant leakage in the whole machine.
Anti-Corrosion Sealing Treatment: Adopt high-temperature curing epoxy coating and integral sealing process to enhance dustproof, waterproof and anti-oxidation capabilities.
Full-Function Performance Calibration: Test and calibrate clutch sensitivity, operating pressure and refrigeration cycle to ensure stable and consistent overall performance.
Shockproof Professional Packaging: Adopt foam buffer + thick carton outer packaging to prevent collision damage during long-distance international transportation.
