This unique bubbler allows for fine control of purge gas within an inert gas system such as a manifold. Purge gas enters the bubbler through hose connection (A) and exits through connection (B). The large capacity of the main chamber (C) allows for rapid purging with check valve protection of the inert gas source (D). The constriction of the large chamber prevents oil from being drawn back into the system. The small chamber (E) is equipped with a pressure release valve which is adjustable from 2 to 49 lbs. PSI. (4 lbs PSI is recommended for most vacuum/inert systems). When charging the system to the correct pressure setting, the bubbler in the main chamber will cease to operate and permit any over-pressure to escape through the small chamber. Overall height is 300mm, overall width is 150 mm. Hose connections have an O.D. of 11 mm at the largest ring.
NOTE: This item is designed for use with mineral oil. During normal operation, chambers D and E must be filled half way with mineral oil.
