Oil-Free Vacuum for Harsh Chemical Applications

Labs and industrial environments dealing with aggressive chemical vapors often face downtime and maintenance costs from oil-based vacuum systems. Welch’s ChemStar Dry system eliminates oil contamination risks while maintaining high chemical resistance and reliable performance. It’s built for users who need continuous operation in corrosive settings without the hassle of oil changes or vapor recovery systems.

Why ChemStar Dry?

1. Oil-Free Operation

No oil means no vapor contamination, no disposal headaches, and no maintenance tied to oil degradation. ChemStar Dry uses PTFE and other corrosion-resistant materials to handle aggressive vapors without breaking down.

2. Built for Harsh Chemistry 

Designed for applications like rotary evaporation, vacuum drying, and distillation involving solvents such as TFA, DMF, DMSO, and acetonitrile. The system’s wetted surfaces resist corrosion and extend pump life.

3. Quiet and Compact 

Operates at 52 dB(A), making it suitable for lab environments. The footprint is compact enough to fit under benches or integrate into fume hoods.

4. Smart Performance Monitoring 

Includes a vacuum gauge and controller for precise regulation. Users can set vacuum levels and monitor performance in real time, reducing process variability.

5. Long-Term Cost Efficiency 

No oil changes, fewer part replacements, and reduced downtime. ChemStar Dry is engineered for long service intervals and low total cost of ownership.
