Blower Vacuum Pumps (Oil-Free)

Welch's ChemStar Dry oil-free vacuum blower series is perfect for labs favoring time-efficient and hassle-free vacuum operation.

The ChemStar Dry was designed to provide laboratories with an alternative to belt-drive vacuum pumps. As effective as belt-drive pumps are, their oil-based design necessitates regular upkeep and maintenance. By incorporating a vacuum roots blower and a chemical-resistant diaphragm pump, the ChemStar Dry eliminates the need for oil altogether.

This oil-free design -- along with its custom control software and integrated self-cleaning functionality -- makes the ChemStar Dry a plug-and-play alternative for those labs that want to save both time and labor.
