Product Description

Product Introduction

The combination of a screw vacuum pump and a Roots vacuum pump allows
for efficient pumping and higher vacuum. The screw pump and roots pump
combination works by using the screw vacuum pump as the primary pump and
the Rotz vacuum pump as the secondary pump. The screw pump draws in the
gas, compresses the gas and expels it into the roots pump. In the roots pump, the
gas is discharged into the vacuum chamber and pumped out, thereby achieving a
higher vacuum and a lower back pressure

 

 

Advantages of Dry Pump Unit:

1. High vacuum: The ultimate vacuum can reach 0.1 Pa.
2. High pumping speed: Ranging from 330 m³/h to 4240 m³/h.
3. High energy - saving rate: 30% - 50%.
4. Oil - free and water - free dry operation.
