Description FeaturesThis new single stage design using balanced valve stem technology is more sensitive than older two stage technologies providing g better performance even with high inlet pressures. This regulator is designed for use with instruments that use a pump to draw the calibration gas into the instrument. The 3950 series demand flow regulator provides the exact amount of calibration gas the instrument pump requires. This simple to use regulator makes calibration quick and easy by eliminating the need for sample bags, flowmeters, or special operator training.
• Precise delivery of calibration gas required by instrument pump.
• New single stage balanced valve stem technology.
• Simple easy to use operation.
• Various cylinder connections available: C-10, CGA 600, other CGAs.
• 40 micron inlet filter.

Description FeaturesThe 3980 series provides the control of the single fixed flowregulators with the advantage of being able to change flowrates as required for different applications. This regulatoreliminates the need to have multiple regulators on-site.Commonly called the “click” regulator it has 12 flow positions, OFF, 0.3, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 5.0, 6.0, 7.0, and 8.0 slpm. There are models suitable for use with non-corrosive gases and mildly corrosive gases.
• 12 fixed flow settings.
• 0-3000 psig cylinder pressure gauge.
• Max. inlet pressure 3000 psig.
• Available with standard C-10 (5/8”-18 UNF) or a standard CGA cylinder connection.
