Since we invented the Twin Lobe Blower, so synonymous has the name of Roots become, that it is common to refer to these PD blowers as 'Roots Blowers'. However, the only true Roots Blowers are those that are supplied by Howden.
PD Blowers work by drawing in air through an inlet and then against the system pressure forcing that trapped air out the outlet side. They are perfect for delivering reliably constant pressures, and the flow can be altered based on the operating speed.
All Howden Roots blowers are of a compact, sturdy design engineered for continuous duty and maximum reliability. These blowers have a time tested lubrication system and an exclusive “figure-8” gearbox design improves oil distribution to the timing gears and lengthens bearing life.
Incorporating our innovative Whispair™ technology for low noise, low pulsation compression, Howden continues to lead the way when designing and maufacturing PD Blowers.
Manufactured using Whispair or DVJ/DPJ principles
Backflow can be reduced and controlled within the units
Operation does not require lubrication within the lobe cavity
Wide range of sizes and specifications
Vertical or horizontal installation options
Cost effective design
In 2011, Howden began operating the largest-ever installation of its Roots IntelliView controls system at Bird Island’s aeration basins.
