Roots Vacuum Pump

The pump is based on the second generation of pumps on the basis of innovation, with the characteristics of the second generation of pumps.
Characteristic：
A, design innovation: Rotor line optimization design, the key is not the structure optimization, material configuration is more reasonable.
B, process innovation: the key components of the use of metal mold casting, resin sand molding, digital processing, the appearance of no putty paint.
C, better performance: zero flow compression ratio, high vacuum limit, high reliability.
D, shape innovation: to increase the effect of heat dissipation design, beautiful appearance, has applied for design patents.
