Vacuum Pump, 750W V-I280SV Bipolar Refrigerant Pump 14.4M3 /H Screen Bonding Dual Stage for New Air Conditioning Servicing

1, high ultimate vacuum, high pumping speed design: two-stage rotary vane design improves the ultimate vacuum and pumping speed reduces the exhaust time of the pump. 2, the structural design of the pump: pump parts with the overall design, while using a cylindrical pin connection between the body, improve product reliability and ease of maintenance of the pump. 3, forced oil inlet design: with internal vacuum pump, which can produce a constant pressure of the oil supplied to the pump chamber and plain bearings, to ensure they are in good state of lubrication and sealing, and 4, anti-back oil structural design: the intake port install solenoid valve and vacuum table, when the pointer to the zero position, taking the job is completed, the system automatically cut off after being drawn off; can effectively prevent vacuum pump oil into the container to be working, the working container within a certain period of time to maintain the vacuum state, and to protect the cleaning container. 5, gas ballast design: when the vacuum pump, the gas ballast valve into the amount of non-condensable gas to dust compression chamber to reduce the gas is pumped condensable condensation level in the pump. 6, long-lasting filter design: the intake filter can effectively prevent foreign matter into the pump chamber, complement can effectively separate the oil mist from the exhaust.
