Pneumatic systems are best suited for applications which require no risk of contamination because they offer a very clean environment for such industries as biotech, dentistry, pharmaceutical, and food suppliers.

For hydraulic oil, a rule of thumb is that it will compress 0.5% for every 1000 psi that is exerted. • Hydraulics will leak fluid. As an example, a 2-in. In general, it is a good rule of thumb to use hydraulic systems primarily for heavy lifting applications such as the jaws of life, elevators, hydraulic presses and arms in heavy equipment, and wing flaps for airplanes because these types of systems operate at higher pressures (1 500 to 2 500 psi), generating higher force from small-scale actuators. The biggest difference between the two types of systems is the medium used and applications. The air or gas used in a pneumatic system is typically dried and free of moisture so that it does not create issues to internal components. A pneumatic control valve. Pneumatic systems require low maintenance and have long operating lives. That doesn’t account for hydraulic cylinders, pneumatic system parts, maintenance of these parts, etc. We will take a look at the two processes and find out what the main differences between them are as well as some of the practical applications. 1. Shorter life cycle: Hydraulics have a … You would laugh as it flew across the room making hilarious noises. They use the power of moving liquids in a similar way. Contrary to popular belief, liquids are compressible. We also use third-party cookies that help us analyze and understand how you use this website. Hydraulic tools When looking at pneumatic and hydraulic systems it’s hard to say if either is more common than the other, rather each have their own specialties which make them unique for their corresponding applications. The cost-effective pneumatic conveying systems provided by Nex Flow are simple, light weight, compact, reliable, and easy to install and use. Pneumatic vs. Pneumatics work like the speedy running back and hydraulics do the heavy lifting of the offensive line. 2. Pneumatic systems are easy to install and portable. In hydraulics, liquids are relatively incompressible. It uses compressed air, not electricity, so there is no explosion hazard. Gases are readily compressible, have a low specific mass and do not have a free surface. Unlike hydraulic systems that use liquids that transfers force, gas absorbs excessive force. Nex Flow Air Products Corporation manufactures compressed air products for blow off, industrial cooling (Vortex Tubes), air operated conveying, and air optimization designed to reduce energy costs while improving safety and increasing productivity in your factory and manufacturing environments. Compressed air operated pneumatic conveyors are designed to move materials at high rates and over long distances. Due to the risk of potential hydraulic oil leaks from faulty valves, seals or hoses – hydraulic applications do not apply to anything that would be ingested – such as food and medical applications. During configuration and planning, if the factory or plant has several hydraulic machines, it is ideal to have a central power unit to reduce noise levels. Nex Flow also provides fume and dust extractors, Ring Vac Operated conveyors and an X-StreamTM Hand Vac system. Summary: Since Pneumatic systems run on compressed air, there is very little chance of fire compared with explosion or fire hazard of using compressed hydraulic oil. The pros and cons of each term are numerous and varied: Hydraulic System : Advantages: The hydraulic system is a power transmission device.
