General Specifications




   Type / Applications       
   Your choices are...
 
      
 
   Gerotor Air Motors
 
     Gerotor air motors deliver high torque at low speed without additional gearing. When coupled with a 2-stage orbital planetary gear train, gerotor power elements provide torque at speeds down to 20 rpm. These motors are well-suited for hazardous-environment applications where relatively high torque is needed in limited space.
 
   Milling Motors
 
     Milling motors are motors used for milling.
 
   Motor / Engine Starters
 
     An air motor can be used as a starter for large diesel, gas turbines, or electric motors. Air motors used to start engines, turbines, or other rotary equipment. Air starters are flexible, efficient alternatives to electric sources. They create sheer power from the natural environment and are perfect for a wide range of industrial, marine, and automotive applications.
 
   Piston Motors
 
     Piston air motors are used in applications requiring high power, high starting torque, and accurate speed control at low speeds.
 
   Turbine Motors
 
     Efficiency of an air motor is defined as the ratio of the actual power output to the theoretical power available from the compressed air for the expansion ratio at which the machine is operating. Turbines convert pneumatic power to mechanical power at about 65%-to-75% efficiency. Turbine efficiency is higher than other air motors because sliding contact of parts does not occur to cause internal friction. As a result, there is no need for extensive lubrication. The absence of lubricating oil dramatically improves cold-weather performance.
 
   Vane Motors
 
     Rotary vane motors normally are used in applications requiring low-to-medium power outputs. Simple and compact vane motors most often drive portable power tools, but certainly are used in a host of mixing, driving, turning, and pulling applications as well.
