A quality of compressed air for use with pneumatic / electro-pneumatic instruments and controls (usually dry and free from contaminants)
In other words, Instrument air is a supply of compressed air that is treated and conditioned for use in process control instruments and equipment. The treatment usually involves removing moisture, oil, and other contaminants that could potentially interfere with the operation of the instruments.
In practical settings, instrument air is used to actuate control valves, drive pneumatic tools, operate air motors, perform purging, and a variety of other functions within industrial applications.
The critical characteristic of instrument air is its high purity, which is essential to maintain the accuracy and reliability of pneumatic controls and instrumentation.
It’s crucial to maintain the quality of instrument air as substandard or contaminated air can result in the malfunction of delicate equipment, leading to potential safety concerns and negatively impacting the overall efficiency of an operation.
The specifications and standards for instrument air are often defined by industry bodies and may vary based on the specific application and industry.
