General description

For use with lecture-bottle gases.

The combination of Monel regulator components and proper purging with the cross-purge assembly makes these units virtually impervious to attack from strong acid forming gases that include hydrogen chloride, chlorine, hydrogen fluoride, hydrogen bromide and silicon tetrafluoride. Cross-purge assembly eliminates the escape of toxic and flammable gases when changing cylinders and permits purging system with dry, inert gas to prevent corrosion due to gas hydrolysis.
