The Science of Movement with Air
The fischertechnik PROFI Pneumatic II set provides you with an engaging, hands-on method for teaching students the fundamentals of this air-based technology. Using numerous application examples, students will learn how pneumatic valves and cylinders work in connection with a compressor and an air cell.

The PROFI Pneumatic II set contains four double-acting pneumatic cylinders, three 4/3 way hand valves and one electrically operated compressor with air cell.

REQUIRES a 9V battery (not included)

• REQUIRES a 9V battery (not included) or Accu Set (#57487) sold separately.
• STORAGE SUGGESTION: with each PROFI Pneumatic II set we recommend 4 Sorting Box 500--258x186 (#94828) with dividers and 1 Base Plate 258x186 Cover (#32985).
• Additional Information for Educators and Administrators
• This set can be used in the classes addressing the following topics: Physics, Mechanical Engineering, Pneumatics
• Specific concepts addressed with this set: Pneumatics and how they work.
• History--The origins of pneumatics and the utilization of compressed air devices.
• Pneumatic Cylinders--Experiment with the different types of pneumatic cylinders—“single acting” or “unidirectional cylinders” and “double-acting” cylinders, and observe how they function.
• Pressure--Learn about Pressure and the formula for calculating it. Pressure equals force divided by area. The unit for pressure is called “bar” or Pascal.
• Force--Determine what forces you are able to exert with your cylinders by constructing a model of a lifting platform.
• Experiment with Check Valves and Hand Valves.
• Build a working model of an Air Compressor and perform further experiments with the lifting platform model.
• Learn about the principle of" “more power through more surface area”" by utilizing multiple cylinders in your experiments to lift heavier weights. Force equals Pressure times Area.
• Build a working Pneumatic Catapult.
• Build a model of a Pneumatic Sliding Door to learn more about the use of valves.
• Build a model of a Turntable with a Press and a Linear Feed, such as might be used to assemble components in a modern factory.
• Build four different pneumatic vehicle models—a Pipelayer, a Snowplow, a Shovel Loader, and an Excavator.
