BSJ70L Mechanical Booster Vacuum Pump 70L/S Roots Blower Vacuum Pump

Product Specification

Whole Aluminium Alloy Made 70L/s 50Hz 0.75kW Army Green Booster Pump, Mechanical Roots Pump BSJ70L

• Achieving high-vacuum conditions: It can pump gases out of a sealed chamber to create a high-vacuum environment. It is often used in applications where a high degree of vacuum is required, such as in semiconductor manufacturing, vacuum coating, and scientific research.
• Enhancing pumping speed: The roots vacuum pump has a relatively high pumping speed, which means it can remove gases from a chamber quickly. This is important in processes where rapid evacuation is necessary to save time and increase productivity.
• Operating in combination with other pumps: It is usually used in series with other types of vacuum pumps, such as rotary vane pumps or diffusion pumps. The roots pump can handle the initial stages of pumping to quickly reduce the pressure in a system, and then the other pumps can take over to achieve even higher vacuum levels. This combination allows for efficient and effective vacuum generation across a wide range of pressure levels.
• Handling different types of gases: It is capable of pumping various types of gases, including air, nitrogen, and some organic vapors. However, its performance may vary depending on the specific gas being pumped.
• Maintaining vacuum stability: Once the desired vacuum level is reached, the roots vacuum pump helps to maintain the stability of the vacuum by continuously removing any gases that may leak into the chamber or be released from the materials inside the chamber.

​Technical Parameter :

Note:

^*1 The value changes depending on the performance of the fore pump. The above data is obtained when the pump is used in combination with a standard fore pump.

*2 The value of 'Ultimate Pressure' in this sheet is measured by the Pirani gauge when the Baosi special pump oil is used, and the value should be 4x10^-3 if the McLeod gauge is used.
