Air is contaminated – all air. It’s a good idea to find out the type of things air may be contaminated with. This is especially important when it comes to compressed air, as it is used for certain processes that require certain specifications.
Types of Compressed Air Contaminants
There are three main types of contaminants in compressed air. These three contaminates include the following: aerosols, vapors, and dry particulates. The dry particulates are precisely what they sound like. They include dirt and an array of other very small solid particles.
Vapors are gas-forms of particles that will condense into liquids when at lower temperatures (i.e. water). The gas stated is what lets these “liquids” exist in the air. Aerosols are extremely fine, solid particles that can get trapped in gas or air, and that gets suspended. An example of aerosol is airborne dust.
Understanding Compressed Air Contaminants
While you can use donaldson compressed air filters to help reduce contaminants, it’s still a good idea to understand them. Every contaminant has unique properties and characteristics, which may require its own filtration methods.
There are two types of filtration to use in a compressed air system. One is dry particulate filtration and the other is vapor and aerosol filtration. Each one provides the needed benefits but works for different particles.
What Type of Filtration System is Needed?
When you are trying to figure out what type of filtration system you need, there are several things that must be considered. Along with the particulates in the compressed air system, you have to consider the surrounding environment, as this may introduce more particulates.
By understanding the factors here, you can figure out the right filtration system for your needs. This is going to ensure you remove the particulates present and that the air is clean.
