Compressed air is used in thousands of commercial and industrial applications. It can be used to power rotary equipment, drive reciprocating equipment, operate controls, cool, sandblast, paint, clean, aerate, etc. Compressed air is so pervasive in industry, it’s estimated around 10% of industrial energy usage is for producing compressed air.

Handling compressed air generally means ensuring the proper amount of air is delivered at the proper pressure for the task. Pneumatic flow meters and pressure gauges are critical pieces of equipment in this regard.
