We are proud to represent the Dresser Roots line of blowers and compressors.
Dresser Roots manufactures a full line of rotary-lobe and centrifugal air and gas handling blowers as well as vacuum pumps. In 1854, Roots pioneered the rotary-lobe blower design and has extensive experience with a wide range of applications and industries. Roots centrifugal units range from 2 cfm to 250,000 cfm, with pressures to 30 psig, and single stage vacuums to 28" Hg.
A rotary positive blower, sometimes called a Positive Displacement, or PD blower, is a machine that "pushes" a relatively constant volume of the gas handled at the inlet through to the discharge. It doesn't internally compress the gas, so it isn't considered a compressor. The amount of gas the machine handles is fixed by the configuration of the casing and rotating parts.
Flow through a PD machine is relatively constant, regardless of pressure changes. This is different from a centrifugal compressor, which maintains a relatively constant pressure while the flow varies.
