▍Features
GLD-series is an oil sealed rotary pump of high performance, high quality and high reliability. lts creative design of the cooling fan realizes incomparable high vacuum degree and improves heat dissipation effect. Besides the advantage of low vibration and low noise, the large observation window also allows users to check oil pollution easily.

▍Applications
Automatic pumping line of compressor refrigerator, Air-conditioner, water dispenser Physics and chemical experiments, analyzing appliances, laser-related facilities.High- vacuum pumping systems, backing systems for electronic microscopes Semiconductor manufacturing equipment, sputtering evaporation,illuminant.Vacuum drying. freeze drying ,Analytical instruments and leak testers.

▍Specifications
