Air that is squished tightly is very valuable for powering things. It's secure, strong, and trustworthy. It's used a lot in industries like electronics, car-making, medicine, chemistry, making metal things, and making fabric. If we don't clean the compressed air, it has dirt that can harm how we make things.
The dirty things in the air that make it harmful are mostly tiny pieces of dirt, oil, and water. If they are not taken away, they will blend to make a harmful liquid that can eat away equipment, spoil goods, and stop production.
There are three ways that things that aren't liquids can end up in the air: from machines that move a lot, from the air itself, and from pipes.
Oil is necessary for the compressor to work properly. It helps keep everything working smoothly, and also keeps it cool. But because there's oil in the air around us, the air that comes out of the compressor also has some oil in it.
There is a lot of water in the air and how much there is depends on the temperature. Some things are easily damaged by water when being made or used.
So, in the equipment that cleans compressed air, the filter is really important because it's easy to use and can fix the problem of bad air quality. However, there is a small restriction that comes with the filter. The filter needs to be serviced after a certain period of time. When it's time to, you need to change the filter, and you'll need to buy more supplies. Some filters can only work within a certain range.
When picking equipment to clean compressed air, it's not just about the filter. You should also use things like a cold dryer or degreaser for the best results and a good price.
A filter that cleans and purifies compressed air is called a compressed air filter. We talk about special filters that work really well in air pipes. They are called high-efficiency precision filters.
Compressed air has two kinds of dirty stuff called pollutants. The air that goes into the compressor has harmful things in it. 80% of these harmful things are very small, less than 2 micrometers. When they go through the compressor, they become tiny droplets called an aerosol. These droplets are between 0.01 and 0.8 micrometers in size.
If there is dirt in the air system, it can cause big problems. When air gets smaller, unwanted dirt gets pulled into the machine with it. In an air system that's squished to 0.8MPa, the dirt and bad stuff becomes 8 times worse. Right now, tiny dirty things can harm stuff made with squished air. These things that can make the air dirty are dust from pipes, tiny pieces that come off things when they rub together, black stuff from burning things, and very small living things. You can divide it into three groups: big dust, particles bigger than 10 μm. Tiny pieces of dust that are between 10 and 1 micrometer in size. The smallest dust, with particles less than 1 μm.
The filter can get rid of a lot of small bits in liquid and solid forms that are usually bigger than 1 μm. We need a really good filter to get rid of tiny solid bits and oil droplets mixed with water. The filter helps remove dirt and dust from compressed air. It can also block some liquids like water and oil. It's different from regular filters. The filter works really well and can remove almost all of the unwanted things.
