If you’re like most people, you monitor or calculate your gas mileage for your car in order to make sure it is running efficiently. This same thing can be done for an air compressor or even a complete air compressor system. For most compressed air systems running around 100 psi, the specific power in kilowatts […]

It’s possible to use compressed air storage like a bank account to ride out deficits in compressed air capacity that might ordinarily cause the plant pressure to fall to unacceptable levels. Consider the pressure/amp profile shown at the right. The compressed air demand exceeds the capacity of the compressor on two occasions causing the compressor […]

The lowly condensate drain is incredibly important to the quality of the compressed air in a system. The most important ones are those located in the air compressors at the bottom of the water separators, and the next most critical within a refrigerated air dryer. Without these drains, the water squeezed out of the compressed […]

While contemplating compressed air problems over a pizza lunch, an air auditor started doing some quick calculations concerning the size of his pie and the relative cost. He found he could get a 6-in. pizza for 5 dollars but if he went with an 8-in. size, he would only have to pay 7 dollars. Using […]

By Ron Marshall In any manufacturing plant, there is an assortment of blowing nozzles where compressed air is used to clean product or debris.

A technical high school had to replace its 12-year-old lubricated screw air compressor after 100,000 hours of operation. The unit had simply worn out after many hours of operation. The school maintenance staff was unaware that some screw compressors, if installed with very little storage, will run unloaded continuously, consuming significant power but producing no […]

A metal processor has a six-day per week production cycle with Sunday off.  To save energy, the staff turns the compressed air equipment off during the down time. Recently, a compressed air auditor installed a dew point probe on the system — and found that on start-up there was a dew point spike to as […]
