The AUTOOL Refrigerant Recovery Machine is the ideal choice for repair shops with specific requirements. Its deep internal vacuum technology limits refrigerant loss to under 50 grams when switching between different refrigerants, ensuring zero cross-contamination between two refrigerants. Equipped with dual refrigerant tanks, it eliminates the hassle of frequent tank changes for operators. Its unique design allows for quick unlocking of the weighing sensor, making maintenance simple and cost-effective. The system also features self-diagnostic capabilities and supports convenient USB upgrades.

Working Principle

Vacuuming: Utilizes a vacuum pump to remove air and moisture from the refrigeration system, ensuring no impurities affect the refrigerant flling process.
Refrigerant Filling: Uses a flow control valve and pressure sensor to precisely transfer refrigerant from the storage tank into the refrigeration system, completing the filling process according to the preset amount.
Smart Monitoring: Real-time monitoring of pressure and flow to prevent overfilling or insufficient filling. Automatic shutoff and alert for abnormal conditions.
Safety Protection: Continuous monitoring of temperature and pressure to prevent refrigerant leakage or overpressure, ensuring the safety of the equipment and operators.
The core lies in vacuuming, precise filling, and intelligent control, achieving an efficient, safe, and environmentally friendly refrigerant filling process.

How to Choose LM Series Refrigerant Recovery Machine Products?

I frequently service high-end vehicles like BMW, Porsche, and Audi. Which model should I purchase?

We recommend the LM708. It supports both HFO-1234yf refrigerant and R134a, allowing seamless switching to meet the diverse needs of automotive repair shops.

Can this machine be used for EV Car?

Yes, it supports both HFO-1234yf and R134a refrigerants, making it compatible with any vehicle model.

Is this machine fully automatic?

Yes. After presetting the parameters, the equipment automatically completes the refrigerant replacement.

What is the routine maintenance?

Replace the filter after every 100kg of refrigerant replaced. After replacing the filter, reset it on the equipment interface. If no prompt appears, enter the universal password “8609” to complete the operation.

How many vehicles require filter replacement?

Approximately 600g of refrigerant is used per vehicle. A 100kg refrigerant supply suffices for about 166 vehicles. We recommend inspection after servicing 140 vehicles and purchasing filters in advance.

⚠️ Must Read Before Use

The new LM707/708 automotive refrigerant recovery machine requires filter replacement after every 100kg of use.
After replacement, reset the filter on the device interface.
If the device does not prompt you, directly enter the universal password “8609” to complete the operation.
If you have an older LM707/708 model, please contact us.

🔔 Warm Tips

The refrigerant tank of this equipment contains liquid refrigerant. Overfilling the refrigerant tank may cause an explosion. Do not turn off the overfilling safety protection function. The refrigeration tank should always be placed on the load unit platform when operating the equipment.
Please read the instructions carefully before the operation. Improper operation may result in serious consequences, such as damage to the air conditioning system or damage to the equipment.
Please only use the special refrigerant tank recommended by the manufacturer.
Please avoid breathing refrigerant or oil vapor/mist and read the material safety instructions on the refrigerant and oil packaging.
To avoid the risk of fatal electrical shock, always remove power from the equipment before disassembling or servicing it.
To avoid contact with refrigerants, safety glasses, and gloves must be worn to protect your eyes and skin. In case of contact with liquid refrigerant, flush the affected area with plenty of water and consult a physician immediately. Contact with liquid refrigerant may cause frostbite and blindness.
Avoid using extension power cables with copper core diameters less than 1.5mm².
Do not store gasoline or other flammable substances near the equipment.
Replace the filter drier for every 100 kg of refrigerant recovered. To replace the filter, you need to contact us and enter the corresponding password.Online Support>>
