Piston air motors

While it is undeniably true that piston air engines are good tools thanks to their high starting and stall torque, there are a lot of situation where their size, weight and low RPM make them unsuited for many different applications. They hence are often replace by classic vane air motors for such applications, even though the typical features of such motors don’t allow for an optimum use, since their stall and start torque tend to be insufficient. This is where MODEC’s compact vane air engines unveil their entire usefulness and uniqueness. The unique design of MODEC’s compact compressed air engines, which includes a planetary gear box system, proposes both of vane motors’ and piston motors’ strength, while setting aside all weaknesses of both models. We thus find small, light air motors that achieve both a high RPM and a high starting torque that can be adapted to all applications.

No more need for a compromise between high RPM typically given by rotary vane air engines and high starting torque typically given by geared piston air motors!
MODEC has finally found how to make an air motor suitable for all applications, may there be a need for high speed or high torque. The five-stepped torque reduction system makes MODEC’s engines suitable everywhere, no matter the needs or technical constraints.
The numerous innovations developed by MODEC, such as the epicyclic gearing system, flow reduction, coupling rings and pressure control systems allows them to offer performances usually seen with piston-based air engines in a more compact, light and simple motor design able to achieve higher RPM.
