Course project, about 16 hours
Clamp-and-press station with a hydraulic power unit: sequence, sizing, I/O and commissioning for a hinge factory
Design, size and document a bush-pressing station for cabinet hinges. It has three pneumatic cylinders running A+ B+ C+ C- B- A- with sensors. It has a two-hand start and an E-stop that exhausts the island safely. A 3 kW hydraulic power unit drives a 63 mm swaging cylinder at 120 bar. You deliver the FluidSIM circuits, a relay ladder, your own sequence narrative, I/O list, sizing datasheet and commissioning record. The sample document pack shows what a fluid-power integrator hands over with the machine.

Practise what you learn in the free 3D lab
Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.
- Practise safely, so a mistake costs nothing.
- The lab checks your work like a site test, so you know when it is right.
- Free, in your browser, with nothing to install.
Why learn with EDWartens

- Free from the first lesson to the final assessment.
- Practice in a free 3D lab in your browser, with nothing to install.
- Video lessons with written notes and a project.
- An optional certificate that anyone can verify online.
- Free internships to keep practising afterwards.
Common questions
What is the difference between pneumatics and hydraulics?
Pneumatics uses compressed air and hydraulics uses pressurised liquid, usually oil, so hydraulics delivers much higher forces while pneumatics is lighter, cleaner and cheaper. Festo describes a pneumatic cylinder as a drive operated with compressed air usually up to a maximum of 12 bar, and says pneumatic cylinders generally operate at lower speeds and less force than hydraulic or electric ones but are a clean and cost-effective option. The course starts with this comparison and then covers each side in turn, from air preparation to hydraulic power units.
What standard are pneumatic and hydraulic circuit symbols drawn to?
The international standard is ISO 1219: Part 1 covers the graphical symbols and Part 2 covers circuit diagrams. ISO states that ISO 1219-1:2012 establishes basic elements for symbols and specifies rules for devising fluid power symbols for use on components and in circuit diagrams. Reading and drawing pneumatic and hydraulic symbols and circuits is one of the first skills this course teaches.
Are pneumatics and hydraulics skills in demand?
Yes, particularly in industrial maintenance, where fluid power is part of the core training. The US Bureau of Labor Statistics projects employment of industrial machinery mechanics, machinery maintenance workers and millwrights to grow 14 percent from 2025 to 2035, much faster than the average for all occupations, and names hydraulics and pneumatics among the courses in industrial maintenance programs. This course ends at the relay ladders that control cylinders, the boundary where maintenance teams work.
Is this for mechanical or electrical people?
Both. It starts with air and oil and ends with the relay ladders that control them, which is exactly the boundary maintenance teams work on.
Do I need FluidSIM?
Only for the simulation module. Festo offers a FluidSIM trial (check its current length and terms on Festo's site); the rest of the course needs nothing installed.
How much maths?
Force, area, flow and power: multiplication and division with units.
Is the Industrial Pneumatics and Hydraulics course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate do I get, and is it a vendor qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a vendor credential and is never described as one.
Who made the video lessons in the Industrial Pneumatics and Hydraulics course?
The creators named in the Credits block at the foot of this page, on their own YouTube channels. EDWartens did not make the videos and the creators are not affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks and the assessments.
How long does the Industrial Pneumatics and Hydraulics course take?
Plan on about 35 hours in all, including the video lessons, notes and practice tasks. It is self-paced, so you work through the fifteen modules at your own speed.
Do I have to use the lab?
No. The lab is optional practice. You can skip it whenever you like, and it never blocks your progress, the final assessment or your certificate.
Is the lab free?
Yes. Every lab level for this course opens in your browser, free, with nothing to install.
What topics does the Industrial Pneumatics and Hydraulics course cover, module by module?
The Industrial Pneumatics and Hydraulics course has 15 modules. It opens with "Fluid Power Basics: Pneumatics versus Hydraulics", goes through "Compressed Air: Generation, Treatment and the FRL", "Advanced Pneumatic Circuits and Sequencing", "Hydraulic Valves" and "Electro-Hydraulic and Electro-Pneumatic Circuits" and ends with "Final Assessment". The full list with minutes is under "What you learn" on this page.
What can I do after the Industrial Pneumatics and Hydraulics course?
After the Industrial Pneumatics and Hydraulics course: Compare pneumatics and hydraulics and prepare air correctly; Select and size cylinders, valves and vacuum; Design direct, indirect, logic and sequencing circuits and simulate them. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.
What software and hardware do I need for the Industrial Pneumatics and Hydraulics course, and does it cost anything?
For the Industrial Pneumatics and Hydraulics course, software: Festo FluidSIM (Festo offers a trial; check its current terms). Hardware: none required. A pneumatic trainer or any machine with cylinders makes it real. The course itself is free.
Is the Industrial Pneumatics and Hydraulics course suitable for me, and what level is it?
Industrial Pneumatics and Hydraulics is rated beginner. Beginner. Secondary-school physics is enough. It is written for engineering students, apprentices, technicians and working engineers and maintenance technicians, and takes about 34.6 hours at your own pace.
Which jobs use the skills from the Industrial Pneumatics and Hydraulics course?
Skills from the Industrial Pneumatics and Hydraulics course (for example: compare pneumatics and hydraulics and prepare air correctly) are used in roles such as maintenance engineer, reliability engineer, condition monitoring analyst and service technician, and in maintenance technician work. The course gives you practical evidence of the skill; it does not promise a job, and employers decide on experience and interview.
