When selecting an air compressor for your manufacturing operation, the common choice is the industry-standard rotary screw compressor. Known as the work horse of compressed air machinery, the rotary screw compressor comes in a multitude of sizes and power levels. However, centrifugal compressors have seen some exciting technological progress in recent years and offer a wide range of pressures, flow and turndown. Long known for their longevity and durability, they offer higher efficiency, even qualifying for energy rebate programs offered by local utilities and all, notably, produce Class 0 oil free air.
In order for a compressed air system to be designed properly, altitude must be taken into consideration. In order to calculate the demand profile, tool air consumption must also be adjusted for altitude.
Conventionally when we talk about oil lubricated screw air compressor maintenance, it is mostly about replacing consumables such as filters and lubricant on time. While these consumables have a defined usable life and have a direct effect on the efficiency and the life of the air compressor itself when not replaced on time, there are a few critical valves in the air compressor that require maintenance as well.
Sustainability is a high priority for today’s consumer packaged goods (CPG) companies. Driven by environmental responsibility, government regulations and customer preferences, CPGs are actively seeking ways to decarbonize their packaging lines and use eco-friendly packaging materials. Many have started monitoring the energy consumption of their equipment in real time and upgraded critical areas of their packaging processes using two key technologies: pneumatics and ultrasonic welding.
