​Compressed air, like electricity and gas, is an energy medium and therefore must also be conserved and used wisely. Numatics has developed a technique called Numasizing, which enables the resource, compressed air, to be used more efficiently by sizing all the pneumatic components of an air system as well as selecting pressures to optimize its usage. Numasizing negates the need to speculate on the stroke time of an actuator even when subjected to two different loads under two distinct pressures.

In addition to predicting these performance times it determines the HP (horsepower) requirements, terminal velocity stroke times, air usage, individual and system Cv (Pneumatic Conductance) to establish the weakest link in the chain of components, etc. The technique not only takes into account all the necessary physical specifications, pressures and components, but objectives such as energy utilization, increased productivity, minimum size components, etc. or blending of several. What ensues is a tailor made circuit designed to the customer's targets. You must keep in mind that even though it is the same circuit, different valves, components, pressures etc. are necessary to satisfy the varied objectives of the OEM, END-USER, FACILITIES, CONSERVATIONIST, ETC.

Numasizing is not based on a theoretical approach or a mathematical model, but on actual results of over 250,000 test firings of cylinders. They ranged from 3/8" to 14" bores, in conjunction with different diameter/length conductors and valve sizes. The cylinders were subjected to every conceivable dual pressure/load combination feasible. Consequently, it allows us to predict and recommend components and pressures with confidence.
