A farm implement manufacturer expanded its facility about 15 years ago, and personnel decided they wanted a premium compressed air system. They purchased three very efficient two-stage premium compressors, one being a VSD, and connected the equipment with large piping to reduce pressure loss. Filters were mist-eliminator style to reduce pressure loss. Air dryers were […]
Air Compressors
Are pneumatic technologies at risk of becoming obsolete?
Last month, I had the pleasure of attending Pack Expo in Las Vegas for the first time in about five years. I’ve always enjoyed that show, seeing all the packaging machinery and conveyors operating, watching the pneumatics and motion control technologies do what they do best. But I did notice one thing this year — […]
Compressed air fail: Poor sealing methods
If you have ever done leakage detection with an ultrasonic leak detector you will get to know the common leak locations. If you have no detector, there is no excuse these days, excellent equipment is available for you to purchase at a reasonable price, go get it! A common sight — or rather sound — […]
Finding energy efficiency in the cloud
Every manufacturer using compressed air shares the challenge of keeping compressed air systems running efficiently and reliably. Depending on the industry, the compressed air system accounts for 10-50% of a plant’s energy usage and is as essential to uptime as electricity. But compressors are inherently inefficient. Leakage, irregular maintenance, pressure settings, and controls contribute to […]
Compressed air fail: Bearing cooling
A wood products company hired a compressed air auditor to check out its system and try to discover why it now needed to run three compressors rather than the normal two units that previously satisfied the plant demand. The auditor placed instruments on their system to measure pressure, power, temperature, and flow — and quickly […]
Compressed air fail: Breathing air purifier
A metal process plant has two breathing air purifiers installed on site for the protection of its personnel. These units are installed to ensure hazardous Carbon Monoxide is kept out of breathing air. Recently, the two systems were evaluated by a compressed air auditor. When paint fumes or metal particles are in the ambient air […]
Should wet compressed air receiver tanks be outdoors?
During plant inspections, it is often noticed that compressed air receiver tanks are installed outdoors. This is done for a reason — and is a good idea, in many cases, because it benefits the operation of air drying and filtering equipment and produces better quality compressed air when hot summer days cause worst-case conditions. Here […]
Compressed air fail: Remote cooler install
A wood products company called in a compressed air auditor to have a look at its compressed air system. System reliability was poor, and the staff was having issues with the main compressor, a 200-hp air cooled screw compressor that carried most of the plant load. This compressor was rated at 100 psi, but recently […]
Compressed air fail: Vacuum pick-up
A metal products manufacturer had a production problem in one of its processing areas. The maintenance staff had increased the discharge pressure on their air compressors to help with the issue, but it seemed the problem would come back occasionally with no warning. Fig. 1 shows the problematic item, a vacuum pick-up crane. When the […]
How can you spot wasted compressed air?
In a noisy industrial expensive plant, air leaks are everywhere, but hard to detect because the ambient roar washes out the sound of air leaving your system. But strange as it may seem, sometimes you can see compressed air leaks, or more accurately, you can see the result of the air escaping! Fig. 1 […]
