Positive displacement blowers provide a large volume of flow range from 30 to 15,000 m 3 /hour with simpler handing; reduce life-cycle costs, and even quieter operation. However, one thing remains the ...

As with other positive-displacement blowers, the Roots-type has the low-rpm grunt to make a small-block feel like a big-block, basically from idle on up.

The Roots blower is called a "positive displacement" supercharger because, theoretically. it will pump a certain volume of air each revolution, depending on the size of the unit.

Here, substantial credit can be given to ace blower designer Jerry Magnuson; his efforts to improve the Roots-style positive-displacement blower have brought its efficiency throughout the typical ...

The reason for this oversimplification is that the flow rate of any positive-displacement supercharger (Roots-style or twin screw) is a function of the displacement. For every blower revolution, a ...

A positive displacement blower wouldn’t fit in the very compact engine compartment, but guess what? The peeps at Boost District have done it with an Eaton TVS R2650 supercharging kit that ...

Manufacturers of vacuum-excavating machines debate the relative merits of the positive-displacement blower and centrifugal compressor, some saying that the blower is more capable of vacuuming heavier ...
