Making compressed air is expensive. Since air compressors use much electricity to make compressed air, it is important that you use it as efficiently as possible. EXAIR generated a chart with six simple steps to optimize your compressed air system. Following these steps will help you cut overhead costs and improve your bottom line. In this blog, I will cover the sixth step: controlling the air pressure at the point of use.
One of the most common pressure control devices is called a regulator. It is designed to reduce the downstream pressure that is supplying your system. Regulators are commonly used in many types of applications. You see them attached to propane tanks, gas cylinders, and, of course, compressed air lines. Properly-sized regulators can flow the required amount of gas at a regulated pressure for safety and cost savings.
EXAIR designs and manufactures compressed air products to be safe, effective, and efficient. By replacing your “old types” of blowing devices with EXAIR products, it will save a lot of compressed air, which saves you money. But, why stop there? You can optimize your compressed air system even more by evaluating the air pressure at the point-of-use. One of the most common practices is to attach a blow-off device to line pressure. The belief is that the more air that you use, the better the job. For optimization, using the least amount of air pressure to “do the job” can be very beneficial, practical, and save you money.
With Pressure Regulators, they give you the control to set the operating pressure. People tend to overuse their compressed air for many blow-off applications. This can create excessive waste, overwork your air compressor, and rob from other pneumatic areas. By simply turning down the air pressure, less compressed air is used. As an example, a model 1100 Super Air Nozzle uses 14 SCFM of compressed air at 80 PSIG (5.5 bar). If you only need 50 PSIG (3.4 bar) to satisfy the blow-off requirement, then the air flow for the model 1100 drops to 9.5 SCFM. You are now able to add that 4.5 SCFM back into the compressed air system. If we use the average rate of $0.25/1000 ft3 to make compressed air, this would be a savings of $135.00/year at an 8-hour shift. And, if you have many similar blow-off devices, you can see how this can really add up.
By following the “EXAIR Six Steps To Optimizing Your Compressed Air System”, you can reduce your energy consumption, improve pneumatic efficiencies, and save yourself money. I explained one of the six steps in this blog by controlling the air pressure at the point of use. Just as a note, by reducing the pressure from 100 PSIG (7 bar) to 80 PSIG (5.5 bar), it will cut your energy usage by almost 20%.
