Rotary Vane Vacuum Pump is  used for creating a vacuum in various applications,The pump operates by using rotating vanes (blades) that slide in and out of slots in a rotor, As the rotor turns the vanes create chambers of varying volumes, allowing the pump to draw in and compress gases or vapors, ultimately creating a vacuum.The cycle repeats as the rotor continues to rotate, creating a continuous vacuum.Efficient air cooling system.Pumping Speed=1050L/min; Ultimate Pressure=50-pa; Oil Capacity=2l; Rotating Speed=1400-rpm;for more visit Labtron.us
