These "hybrid" compressors offer
the durability and 100% duty cycle of a rotary screw, together with the intermittent
demand and energy savings, of a piston. Under normal operation, the rotary runs
continuously as they are designed to, and the piston automatically runs intermittently;
only when the rotary can not keep up as it is designed to. If no air is required
for 10 minutes the rotary will also turn off and remain in standby mode until air
is required again, providing a seamless supply of air while conserving electricity.
During periods when air demand is
light, you can operate the piston only, again conserving electricity. All with the
added peace of mind of having two separate units that can be operated individually
ensuring you will never be without air.
Systems available up to 55 total
horse-power, delivering 212 CFM @ 100 PSI, maximum pressure up to 175 PSI.
Sizing guide: Determine the CFM required
under normal operation and size the rotary to supply this CFM. Then determine the
peak CFM required and size the piston to supply this additional CFM.

you custom design a system that best suits your application.
