English: A labelled cross-section of a Roots blower with 2-lobed rotors. The rotor form is cycloidal, and in this drawing is drawn accurately. In fact, it is part epicycloidal and part hypocycloidal, and in both cases the smaller generating circle is 1/4 the diameter of the circle it rolls around.
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.

Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
A floor register. A register is a grille with moving parts, capable of being opened and closed and the air flow directed, which is part of a building's heating, ventilation, and air conditioning (HVAC) system.
The first patent of Costin and Densham deals with ways to achieve compression within the Roots-style blower. [2] Although initially focussed on engine superchargers, they were soon to diversify into other application areas, including aircraft cabin pressurisation, refrigeration, reversible air motors and pneumatic conveying of powders and other ...
