Applied Pneumatics and Hydraulics

Course Description

ETM1315C – Applied Pneumatics and Hydraulics is a 3-credit, lab-integrated course within the Engineering Technologies taxonomy (Mechanics, Fluids & Heat). The course provides an introduction to the theory and operation of hydraulic and pneumatic systems, covering principles, components, standard symbols, and industrial applications from both a systems-development and troubleshooting context. Students gain practical, hands-on experience with fluid power equipment used in high-tech production, manufacturing, distribution, and engineering research and development facilities.

This course is a core component of the Pneumatics, Hydraulics and Motors for Manufacturing College Credit Certificate (CCC) offered at multiple Florida institutions, including FSCJ, Seminole State College, South Florida State College, Florida Gateway College, and College of Central Florida. Credits typically articulate into the Associate in Science (A.S.) degree in Engineering Technology.

Lab/Clinical Component

The 'C' suffix in ETM1315C designates a combined lecture and laboratory course. Students are expected to complete hands-on laboratory hours working directly with hydraulic and pneumatic training equipment. Appropriate safety attire (closed-toe shoes, safety glasses) is required in all lab sessions. Lab work involves live pressure systems; strict adherence to safety protocols is mandatory.
