Compressed Air Challenge: Maintaining Peak Compressed Air Efficiency

By Ron Marshall, CET, CEM, for the Compressed Air Challenge (CAC) The compressed air system is often ignored when it comes to maintenance. Under normal conditions, the system’s compressors, dryers, filters and pipes draw little attention, in part because they are often located in a far corner of the plant. Yet when there is trouble, […]

Compressed Air Challenge: Why Is Your Pressure So High?

By Ron Marshall, CET, CEM for the Compressed Air Challenge (CAC) There was a day when most air compressors were rated at 100 psi: Rarely did general plant compressed air systems exceed this threshold. Over the years, however, plant pressures have climbed—and this has cost industrial customers a bundle. A good exercise for anyone involved […]

Overcoming Your Challenges: Efficient Compressed Air Piping

By Ron Marshall, for the Compressed Air Challenge (CAC) Getting your compressed air to flow where it needs to go requires a transmission system—a network of piping that connects your compressors to the end-uses. This piping system can have a big effect on the overall efficiency of your equipment. Around the 100 psi range, for every […]

Compressed Air Challenge: Dry Compressed Air Efficiently

By Ron Marshall, for the Compressed Air Challenge (CAC) Air is like a sponge: It soaks up as much moisture as it can hold. When moisture-laden air is sucked into the intake of an air compressor and squeezed, like a sponge, it releases the moisture it has absorbed. If left untreated, this moisture will flow […]

Overcoming Your Challenges: Remember Your ‘Three 100s’

By Ron Marshall, for the Compressed Air Challenge (CAC) During the heat of summer, a common complaint in many plants involves the issue of wet compressed air. An ugly slurry of rusty, oily, moisture-laden air—smelling much like an old unwashed gym sock—can collect inside piping and spray out on the precious product of your efforts. When […]

Overcoming Your Challenges: Stop Draining Away Your Profits

By Ron Marshall, for the Compressed Air Challenge (CAC) Most compressed air systems incorporate one or more deliberately installed “engineered air leaks” to drain water and lubricant from the system. Unfortunately, these devices often waste significant volumes of expensive air and, ultimately, energy. When air is compressed and cooled to atmospheric conditions (or dried, in the […]
