Atlas' new generation GHS3501900VSD+ variable frequency screw vacuum pump:

1) It saves more than 50% of electricity than water ring pump, and 30% of electricity than old-fashioned screw vacuum pump of Sullair and Quincy.

2) Save the cooling water (compared to some high-end water ring pumps, also save the power consumption of the refrigerator, chilled water, chilled water pipes and the refrigerator which accounts for 33% of the total power of the vacuum pump),

3) The vacuum degree is 3-100 times higher than that of the water ring pump (the water ring pump is generally only about 300mbar, and the Atlas GHS350-1900VSD+ screw pump can easily reach within 10mbar).

4) The cost of consumables is reduced by half compared with the old-fashioned screw vacuum pumps of Sullair and Quincy.
