Vacuum Pump, Pump V-i140sv High Anti Backflow Air High-power Automotive Conditioning Refrigerant for Servicing

1. High-end vacuum and high-speed pumping design: The two-stage rotating design improves the final vacuum, and the pumping speed reduces the pumping time. 2. The original design of the pump structure: The entire pump structure is designed, and the cylindrical pins are used to connect each other, which improves the reliability of the product and facilitates the maintenance of the pump. 3. Mandatory refueling port design: a built-in vacuum pump can provide constant pressure oil to the pump chamber and sliding bearings to ensure that they are in a good lubrication and sealing state, and are equipped with large windows. The low oil level design is more conducive to product use. 4. Anti-oil back structure design: high-quality solenoid valve and vacuum table are installed at the air inlet. When the pointer points to the zero position, the operation is completed, and the system will automatically cut off after pulling out. It can effectively prevent the oil from the vacuum pump from entering the container to work. Keep the working container under vacuum and protect the clean container. 5. Gas ballast design: When using a vacuum pump, use a gas reactor valve to inject non-condensable gas into the dust compression chamber to reduce the degree of condensation of condensed gas in the pumped gas.
