The apparatus includes separated turbines or separated sets of turbines that are operated independently of each other to alternatively create pressure and vacuum conditions for an external system such as a pneumatic delivery network relying upon the inventive apparatus for pressure and/or vacuum generation. A common housing contains both turbine sets and defines a system of internal chambers and valve mechanisms between them. The valve mechanisms respond to internal pressures created within the housing by the turbines, and preferably also to gravity in order to control air flow patterns through the housing and between the housing and an external system. According to the present invention, the turbines of the two turbine sets can be operated concurrently at maximum capacity or separately if air power requirements are lesser.

The speed of lengthwise movement of sections in the conduit is monitored by a sensor which generates signals serving to control the operation of a valve which can influence the speed of the articles by varying the effective size of an outlet for the escape of air from the conduit, and/or to control the operation of a valve serving to admit into the conduit air counter to the direction of advancement of the sections. The purpose of evacuation of appropriate quantities of air from, or of admission of selected quantities of air into, the conduit is to maintain the speed of the sections in the conduit within a desired range regardless of the number of sections in the conduit.
