- Valveco is committed to providing quality products. We are proud to represent the Howden Roots line of blowers and compressors. We stock a large supply of Howden Positive Displacement Blowers and can customize a Howden (PD) Blower package to meet your needs.
- Howden 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.
- 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 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.
- Easy to install, with small footprint.
- Acoustic enclosure is designed to provide up to 22 dBA free field attenuation.
- Broad operating performance range provides a multitude of efficient and compact solutions.
- Air flow from front to rear is designed for personnel safety and equipment reliability.
- Access to air filter is convenient and designed to reduce pressure losses, improving reliability and blower efficiency and protecting your investment.
- Small rotary performance
- Flow rate: Up to 10,710 m3/hr (6,300 cfm)
- Pressure: Up to 15 psig
- Vacuum: Up to 28” Hg
- Large rotary performance
- Flow rate: Up to 120,000 m3/hr (70,000 cfm)
