Welch® improves dry vacuum pump technology with the new DRYFAST® and DRYFAST ULTRA® having built-in Advanced Vapor Management (AVM). AVM means precise control capability for the distillation of organic solvents and applications handling aggressive vapors and gases.

Constructed with solid PTFE heads, PTFE diaphragms, Kalrez® valves and utilizing fluorinated plastics on all wetted surfaces, these dry vacuum pumps are designed to meet your ever-challenging chemical duty laboratory needs.

The six new models feature flows to 70 l/min and ultimate vacuum levels down to 2-Torr. No cold traps are needed to operate. These stand-alone vacuum pumps need very little maintenance leading to low cost of ownership and improved productivity.

Welch® application certifies DRYFAST® and DRYFAST ULTRA® for rotary evaporation, concentrators, evaporators, vacuum ovens, filtration, degassing, and other chemical applications. See back page for the complete model specifications and information.

*Strip DMF at 35C* at 2-4 ml/min (*using dry ice condenser).
