โœฆ Synopsis

Zephyr shows its claws

Rietschle's Zephyr multi-claw series are highly efficient, dry-running pressure/vacuum pumps, air compressors, and vacuum pumps, with applications across industry. These twin-shaft, rotary claw units generate frictionless vacuum and/ or pressure, offering an economic alternative to dry-running rotary vane or single claw rotary pumps.

Unlike traditional rotary lobe designs, their high operating efficiency -and hence low installed motor power, is achieved by internal compression of the gas. The multi-claw has no (wear sensitive) discharge valves, since the rotation of the claws opens and closes the suction and discharge channels.

In this paper, the well-established multi-layer model originally devised by Waggoner and Reifsnyder (1968) is used. This steady-state model based on an electrical analogue simulates the energy exchange between the vegetation and the atmosphere. A purely mathematical development of the basic equation
