6. Pneumatic cylinder - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_cylinder

   [1]: 85 Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage. Because the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement.
