Roots RAM-DVJ Blowers

RAM DVJ WHISPAIR™ Dry Exhausters have an exclusive discharge jet plenum design which allows cool, atmospheric air to flow into the cylinder. This unique design permits continuous operation at vacuum levels to blank-off with a single stage unit. The RAM™ vacuum exhauster’s integral cooling design eliminates the problems caused by high discharge temperatures at vacuum levels beyond 16” Hg. Standard dry vacuum exhausters are limited to approximately 16” Hg vacuum because operation at higher vacuum levels can cause extreme discharge temperatures resulting in casing and impeller distortion and possible failure.
