How much is my timer drain costing me?
When ambient air is squeezed into compressed air, it can’t hold as much water vapor. It’s kind of like squeezing a sponge, free water forms as condensate and will travel down into your compressed air system if not removed. Similarly, when the 100% saturated air the compressor produces is cooled, either the compressed air piping, […]
Compressed Air Fail: Poor control coordination
A manufacturer of automotive products had a two compressor system that was designed for 100% redundancy—however, this system had never been fully implemented. Two air dryers, two large receivers, and two sets of filters were installed, but only two of the planned four compressors had been purchased. An auditor did a plant walk through and […]
How do I make my compressed air system more efficient?
There are three important basic “secrets” to making your compressed air system more efficient. These are 1. Produce the compressed air more efficiently, 2. Waste less compressed air, 3. Use the compressor heat for something useful. To produce the compressed air more efficiently, the work to improve things is mostly done in the compressor room. […]

This high quality product is the most reliable way to remove water/oil condensate from a compressed air system. Designed for use on filter housings, after coolers, dryers, pressure vessels, air receivers and compressors, regardless of size or capacity, the adjustable interval and discharge times allows you to make this unit work at its optimum and […]
What size refrigerated dryer should I buy?
Although it seems obvious, sizing a compressed air dryer is not as simple as merely matching the size of the air compressor. If you want your air dried to proper specifications under all conditions, then some research is required that may require you to adjust to a larger size. Air dryer ratings are affected by various […]
What type of refrigerated dryer should I buy?
When you are in the market for a refrigerated compressed air dryer, it is wise to do some research to find the most economical choice. Air dryers last for many years and can consume a significant amount of energy through the life of the equipment. Choosing a low cost unit that consumes more power can […]
Compressed air fail: High discharge pressure
By Ron Marshall for the Compressed Air Challenge An automotive manufacturer was having trouble with its large centrifugal compressors, which were constantly going into surge condition. This is a damaging condition where the air going through the compressor suddenly stops and starts, shocking the fast spinning rotors in the machines and causing stress on the internal […]
