Pumps can be factory modified to run at other operating pressures i.e. 60 PSI, 50PSI etc. The values shown onthe performance chart will remain the same for all operating pressures.Note 2: Evacuation speed is linear with volume i.e. a 2 cu. ft volume will take twice as long to evacuate as a 1 cu ft. volume.Phone: 1-800-848-8788 or 508-359-7200 E-Mail: engineering@vaccon.com 167
