How much do you really know about compressed air? Our friends at ELGi Compressor put together some of the most common myths to set the facts straight.
Myth: Compressed air is not desirable source of power
Fact: When properly applied, compressed air can be the best choice. It’s a safe, clean source of power that is easy to use and maintain.
Myth: Compressed air is expensive
Fact: Just like any other power source (electric, battery, hydraulic, etc.), compressed air can be costly, but those costs can be minimized through correct application, installation and maintenance.
Myth: Compressed air is dirty
Fact: While poor system design or a lack of basic maintenance can result in some contaminated air, this statement is generally not true.
Myth: More pressure is better
Fact: More pressure isn’t always better. When you raise pressure system-wide it will require more power on-line. If you’ve got pressure problems, they are best solved at the point of use where they exist, not with more power in the compressor room.
Myth: Reducing operating pressure on the air compressor will save energy
Fact: Reducing pressure can save a little money, however, if it’s reduced too much it will become less stable and the system will become less reliable. The first time production is interrupted due to low pressure, operating pressure will be returned to previous levels and your savings will disappear. In the end, it’s not worth the risk to reduce pressure.
Myth: Routine servicing is not required
Fact: The longer you go between compressor service intervals, the more likely it is that your compressor will break down. Ask yourself how long your business can run without compressed air. Skipping maintenance can also cost you in the end. A dirty oil filter can increase your energy use by 2% and a clogged air/oil separator can increase costs by up to 5%. Proper maintenance and changing the oil can save you in the long run.
