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
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.
Whispair rotary blower has an exclusive discharge jet
plenum design that allows cool, pressurized system air to flow
into the cylinder. This unique design permits operation at high
pressure levels with a single stage unit. The RAM high pressure
roots displacement blower is designed for continuous operation at discharge
pressures up to 30 psig. It has no valves, vanes or Teflon rings.
Clean, dry discharge air or gas provides usable heat for your process.
accessories for Roots (PD) blowers, gas blowers, and exhausters include
driver, relieve valves, inlet and discharge silencers, inlet filters,
check valves, extended base, V-belt drive or flexible coupling and
Republic's new Universal Blower Stand for positive
displacement (PD) blower packages utilize a universal mounting
base to fit any size motor.
