Welch™ Economical High Capacity PTFE Diaphragm Vacuum Pumps

Description

• Long life and quiet operation Handles corrosive gases and vapors High flow, continous duty For high vapor flow in larger scale laboratory vacuum applications Used where vacuum pressure requirements are to the low Torr range(∽1.5 to 56 TORR) and low maintenance is a priority All internal parts in contact with gases are made of chemically resistant fluoroplastics Superior vapor tolerance and gas ballast valve for handling heavy vapor loads
• The gas ballast valve preserves the pump performance under heavy vapor load by leaking air into second stage to inhibit condensation Wired 115V, 60Hz with line cord and plug Large vacuum ovens(>5 CF), floor model rotovaps, concentrators, pilot plants, vacuum source for filtration at multiple workstations, and vacuum autoclaves
