Roots type blower served in paper making industry for suction vapor

Roots blower which can also be used as vacuum pump when applied in paper making industry for suction vapor to form vacuum state. The roots vacuum pump can form negative pressure to -50 kpa which is enough for paper making process. Usually a vapor gas separation tank is used before the roots vacuum pump to separate vapor in case entering the roots vacuum pump

Roots blower are a substitue for liquid ring pump, which is more energy efficient. The paticular designed structure ensure low noise and large flow for suction air, which will form a vacuum operation condition.
