description
Equipped with two working chambers, the two-stage rotary vane vacuum pump creates periodically varying volumes within its pump chamber via high-speed rotating vanes, enabling gas suction, compression, and discharge. Gas is first drawn into the front chamber, undergoes initial compression, then is transferred to the rear chamber for deep compression until the desired vacuum level is achieved. This pump is compatible with a wide range of gas media, offering exceptional versatility and adaptability.
Application Areas
Analytical Instruments (spectrometers, mass spectrometry systems, electron microscopes, etc.)
Coating Processes (surface protection, decorative coatings, displays, screens, etc.)
