A new line of tri-lobe truckmount vacuum pumps, redesigned to incorporate the latest technology for reduced noise and vibration, has been introduced by Dresser Roots.

The ROOTS TRI-NADO TM vacuum pumps have an exclusive WHISPAIR discharge jet plenum design that allows cool, atmospheric air to flow into the cylinder. This unique design permits continuous operation at vacuum levels to 28” Hg (at 30” HgA Barometer), along with cooler operating temperatures and lower noise levels, the company said.
