Roots Large Positive Displacement Blowers
Roots DVJ WHISPAIR Dry Exhauster

These blowers have an exclusive WHISPAIR™ 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, without water injection. The DVJ’s cooling design eliminates the problems caused by high discharge temperatures at vacuum levels beyond 16″ Hg.
