The pulp and paper industry depends on reliable sources of energy, water and compressed air; maintaining cost-effective supplies of these utilities is important to every successful business. Within paper making processes, a clean, oil-free air supply is essential for the reliable operation of pneumatic equipment and a high-quality end product. For one manufacturer in Italy, the selection of an oil-free turbocompressor enabled both operational and maintenance costs to be reduced.

Moisture can freeze in compressed air systems and cause rust and pitting in pipes and components. It can also flush out the lubricant resulting in accelerated tool wear and damage to valves and cylinders. Moist air is also a rewarding breeding ground for bacteria, which especially in the food and pharmaceutical industries can lead to product rejection and costly production downtime. It is therefore strange that many companies limit themselves to measuring only basic quantities such as pressure, flow and (absorbed) power.

The dust is collected on the bag or fingers, and when the cake of dust is of appropriate thickness and structure, a pulse or pulses of compressed air hits or shocks the bag and knocks the cake off. This pulse may sometimes be accompanied by physical shaking and even reverse air flows, depending on design.

Would you believe the same technology used in the launching and controlling of a space rocket is also used in your compressed air system? Yes, in some cases, “rocket science” helps to solve problems in compressed air systems and ensures the performance of the installed units. In this article, we are going to explain the technology called the “Sonic Nozzle”, that combines a space rocket thruster and your compressed air system. Additionally, we are going to walk through a case study, step by step, to show how it works.
