BSJ70L 160cfm, 280m3/h Roots Vacuum Pump 50Hz 0.75kW, Army Green

160CFM (280m³/h) 50Hz/60Hz 0.75kW 2Poles Mechanical Booster Pump,Roots Pump BSJ70L

Description :

Roots vacuum pumps, which are also called Roots blowers, are rotary plunger-type pumps where two symmetrically shaped impellers rotate in opposite directions inside the pump housing.

Characteristics:

• The use of an oil-free intermediate seal, multiple sealed ways to ensure a hight clean vacuum environment in the rotor chamber.
• Advanced processing to ensure the good geometrical symmetry of the rotors, as well as low noise and long service life.
• The rotors are made of aluminium alloy, which has the characteristics of fast corrosion resistance and energy-efficient.

​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.

Applications

• Semiconductor Fabrication
• LED & Display Manufacturing
• Vacuum Heat Treatment
• Physical Vapor Deposition (PVD)
• Vacuum Distillation & Drying
• Food Preservation & Processing
• Vacuum Packaging
• Scientific Research

Typical System Configurations

• Roots + Rotary Vane Pump
  Commonly used in general industrial applications (e.g., packaging, heat treatment) to achieve medium vacuum (10⁻¹–10³ Pa).
• Roots + Screw Pump
  Preferred for dry processes (e.g., semiconductor etching) to avoid oil contamination, with screw pumps serving as the backing stage.
• Roots + Turbomolecular Pump
  Used in UHV systems (10⁻⁶ Pa or lower) for research and aerospace, where roots pumps pre-evacuate chambers before turbopumps take over.
