Overview
LM803 Smart Refrigerant Recovery Machine
The AUTOOL LM803 Smart Refrigerant Recovery Machine is a new-generation intelligent refrigerant recovery and charging system developed by AUTOOL. It integrates refrigerant recovery, purification, charging, vacuuming, leak detection, and intelligent A/C system diagnosis into one device, and is designed for the inspection, maintenance, and repair of automotive air conditioning systems.
The LM803 features a 7-inch capacitive touchscreen and a fully automatic operating program. It includes a built-in standard temperature database for R134a refrigerant and a database covering 5,000+ vehicle models. It supports fully automatic quantitative charging, negative-pressure leak detection, refrigerant line flushing, new and used oil management, and system-level fault detection for components such as the compressor, expansion valve, condenser, and evaporator.
After the service is completed, the LM803 can automatically generate and print a service report, helping technicians complete automotive A/C maintenance and repair work more efficiently and accurately.
Product Features
Refrigerant Recovery
Supports fully automatic R134a refrigerant recovery with a recovery efficiency of ≥96% and a standard operating recovery time of ≤20 minutes.The built-in filtration and drying system automatically purifies the refrigerant during recovery, with residual refrigerant in the system of <50g.
Fully Automatic Quantitative Charging
An electronic scale provides accurate measurement with a charging accuracy of ±10g. Both automatic and manual charging modes are supported.The built-in database of 5,000+ vehicle models automatically matches the required refrigerant charge amount. Hose compensation helps improve charging accuracy.
System Vacuuming
Equipped with a two-stage rotary vane vacuum pump with a pumping speed of 60L/min and an ultimate vacuum of <100 microns.Supports vacuum holding tests and automatically determines whether the system has a leak.
A/C System Diagnosis
Based on pressure-temperature analysis, the system automatically evaluates the operating conditions of the compressor, expansion valve, condenser, and evaporator, and provides fault prompts and repair suggestions.The overall diagnostic time is ≤5 minutes, helping technicians quickly locate faulty components.
New and Used Oil Management
Independent electronic scales automatically measure new and recovered oil with a measurement accuracy of ±3g.The system automatically adds the same amount of oil as recovered and supports PAG/POE refrigerant oil.
7-Inch Capacitive Touchscreen
The 1024 × 600 IPS high-resolution display provides split-screen viewing of pressure curves, diagnostic results, and operating procedures.The screen brightness adjusts automatically, and the system supports instant switching between multiple languages.
Automatic Service Report Generation
After the service is completed, the system automatically summarizes the data and generates a printable service report.Supports USB data export and multiple languages, including English, French, Spanish, and German.
Multiple Unit Conversions
Supports automatic conversion between multiple pressure and temperature units.
Multi-Language Support
Supports multiple languages, including English, German, French, Spanish, Russian, Italian, Korean, and Chinese.Language package upgrades can also be customized according to user requirements.
Unique Design
Dark Industrial-Style Design: Constructed with cold-rolled steel and powder coating for rust resistance, corrosion resistance, and resistance to chemical cleaning agents.
Integrated Hidden Printer: The printer features a hidden integrated design, while the screen is tilted at 15° for convenient operation. The control buttons are within easy reach.
Heavy-Duty Wheels: Equipped with 4-inch heavy-duty casters with brakes and 6-inch large wheels for stable and flexible movement through the workshop.
Leak-Proof Bottom Tray and Dust Covers: The bottom leak-proof tray and dust covers for the ports help prevent refrigerant or oil leakage from damaging electronic components.
Emergency Stop and Automatic Pressure Relief: Equipped with an emergency stop button and safety valve for automatic pressure relief, complying with SAE J2927 safety requirements.
3-Year Warranty
For equipment damage caused by non-human factors, AUTOOL provides free replacement parts within three years. If you encounter any issues, please contact us at any time. We will respond promptly within 24 hours. We are committed to taking responsibility for our products, customers, and partners.
