The JZJWLW series Roots oil-free vertical vacuum unit is a pumping system composed of a ZJ type Roots vacuum pump as the main pump and an oil-free vertical vacuum pump as the front stage pump. It is a trend in the vacuum industry in the new century, designed and manufactured to pursue environmental protection, efficiency, and recyclability goals.

2、 Characteristics of JZJWLW series Roots oil-free vertical vacuum unit

1. It can achieve a high vacuum of over 150Pa, and the pumping speed reduction is small under high vacuum conditions.
2. Exhaust gas collection devices can be installed at the exhaust outlet to collect gases that cannot be condensed or condensed without compression, such as cyclohexene, benzene, toluene, alcohols, etc., which are difficult to collect due to their low boiling points and often cause environmental pollution due to accidental discharge.
3. It has the advantages of energy saving, low noise, and low repair rate.
