On behalf of the National Fluid Power Association (NFPA), Greenco Corporation happily donated a number of different types of pneumatic and hydraulic cylinders to the students of the College of Central Florida in Ocala, Florida. The donated cylinders will be used in fluid power courses, starting this semester. "We will be connecting these cylinders this semester and wiring in the reed switches that came with one of the air cylinders. That will actually be used in the motor controls and PLC course work as well. So the donation was actually more valuable than just for fluid powers courses," said Sam Ajlani, their Program Director of Engineering Technology.
A pneumatic system operates under the same principles as a hydraulic system, however a pneumatic system utilizes a gas rather than a liquid. Compressed air is generally used, although nitrogen or other inert gasses can also be utilized for certain applications. With pneumatics, free air is typically drawn into a compressor where it is compressed and then stored in a receiving tank. The receiver holds a vast volume of compressed air to be consumed by the pneumatics framework as required.
