Making Air Systems Clean & Quiet
savings from lubricated air exceed the cost of installing and maintaining the lubricators. * Pneumatic-system exhaust air can be noisy and contain oil mist. * OSHA frowns on in-plant noise and air pollutants. * Coalescing mufflers provide a simple, inexpensive fix. Park Hannifin, Filtration

Needle Bearings
lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty bearings never require relubrication, but high loads or speeds demand it. Compared with other roller bearings, needle bearings have much smaller rollers for a given

Air Dryers
and simple; however, they require that the salt be replenished regularly. In addition, the corrosive salt solution can cause drain traps to clog. Also, a fine salt mist can be entrained in the air and be carried downstream to corrode system components. Deliquescent air dryers can suppress the dew point

Cylinders
the piston, or extremely sensitive response to small pressure variations. They are frequently used as pneumatic actuators in food and drug industries because they require no lubrication and do not exhaust a contaminating oil mist. Spring-return models should not be pressurized in the reverse
