At MGA Controls, we supply a wide range of air preparation equipment from brands such as IMI Norgren, Aventics and Bifold. Air preparation units are extremely important to the smooth running of a process. They provide clean air to compressed air systems, promoting the reliable operation and increased efficiency of an application. In this article, we answer your air preparation commonly asked questions.

What is an air preparation unit?

Air preparation units are a set of instrumentation, commonly sold as filter regulators, that remove particles or contamination from the air stream and control pressure to minimise energy wastage.

What is the meaning of air preparation in a pneumatic system?

Air preparation is a must-have in all pneumatic systems. But why? In order to maximise performance and extend the life of the components within a pneumatic system, air preparation is imperative. If dirty air is sucked into your system there is a high chance of failure for many components. Using air preparation units reduces the risk of a system failure while keeping maintenance costs down and controlling pressure.

How do pneumatic lubricators work?

Pneumatic lubricators work by injecting an aerosolised stream of oil into an airline to provide lubrication to the internal workings of pneumatic systems. They can also be used with other devices, such as actuating cylinders, valves and motors.

What is the maximum operating pressure range of a pneumatic system?

To answer this question, first we must understand what compressed air is and its purpose in a pneumatic system. Compressed air is the air from the atmosphere surrounding your application. This air is then reduced in volume by compression, thus increasing its pressure. This compressed air then transmits and controls energy within your application.

The compressed air is used at a working medium, normally at a pressure of 6 kg/sq mm to 8 kg/sq mm. For use in pneumatic systems, a maximum force of up to 50 kN can be established.

Why is external lubrication necessary in a pneumatic system?

Lubrication in a pneumatic system can reduce both internal and external leakage. Components like valve spools, cylinder rods and pistons benefit from external lubrication because it helps to form a tighter seal in places where leakage is common. This leakage normally occurs due to roughness, even on polished surfaces, as manufacturing processes do not always produce perfectly smooth component exteriors.

Why use a compressed air system in the pharmaceutical industry?

Maintaining a sterile environment is imperative in the pharmaceutical industry. Therefore, using the highest quality compressed air is essential. Any contaminants such as oil can cause process disruptions, production shutdowns and expensive product recalls. Some of the common uses for compressed air in the pharmaceutical industry include process air; controls valves and cylinders; material handling; nitrogen gestation and product drying.
