Welch 202801 Automated Self-Cleaning Dry Vacuum System, 115 VAC, Cole-Parmer (CAT#: STEM-DS-0670-LC)

The Welch Automated Self-Cleaning Dry Vacuum System manufactured by Cole-Parmer is suitable for applications requiring a precise vacuum level. Programmable functions include optional vacuum level, memory for storage of programs, electronic vacuum regulator and digital absolute pressure gauge. The control system uses the digital absolute pressure gauge to show the vacuum degree on a 2-inch 6-digit digital display, and controls the regulator to keep the vacuum degree within 1% of the reading. As a self-cleaning pump, when the pump is turned off, the programmed cleaning cycle remove any vapor inside the pump head to protect the diaphragm and extends the time between required maintenance.
