Air filters (for ventilation or compressed air) use physical barriers to keep things like dirt, water, and oil out so the air stays clean.
Each of them work in different places, use different tools, and have different amounts of stress. The ventilation air filter cleans the air in places like buildings, factories, and workshops where the air is not compressed. It works by using the air around us. The compressed air filter is used in places where the air has been compressed and is carried through pipes. This type of filter can work under a lot of pressure, sometimes up to hundreds of times the usual amount of air pressure.
The coarse filter is used to catch things floating in the air that are bigger than 5μm and things that have settled that are bigger than 10μm. It also traps other stuff to keep it from getting into the clean area. This is used to filter the air at the beginning of the air supply system. It should be efficient in filtering out particles that are 5 micrometers or larger, with an efficiency between 80% and 20%.
This type of filter is good at catching small particles that are between 1 and 10 micrometers in size. This is talking about a filter that is mostly used for air conditioning systems. It works pretty well, with an efficiency of somewhere between 70% and 20%. The filter is especially good at catching particles that are 1 micrometer in size.
There are filters that can catch tiny particles that are 1μm ~ 5μm in size, called high efficiency filters. This is used to clean things really well. It can clean up to 99% of things that are 1 micrometer or bigger.
A sub-high efficiency filter is used to catch really small particles that are less than 1μm in size. To make sure tiny particles that are 0.5 micrometers in size are filtered out, the filter needs to be very efficient, with a percentage range of 99.9% to 99.999%.
A very good filter that is used to trap very small particles that are 0.5μm or 0.1μm in size. The filter works really well with a 99.999% success rate and can remove tiny particles that are 0.3μm or 0.1μm in size.
High-efficiency filters are split into four categories (A, B, C, and D) because it's hard to filter tiny particles. This helps reach different levels of accuracy and cleanliness.
Air filters that help with ventilation are usually made of materials like fiber, glass fiber, and special types of mesh. It has a frame structure and is usually kept outside. It also looks pretty and is dependable. It is pleasant to the eye.
What are the features of air filters that compress air?
The main job of the air filter is to remove dirty things and water from the air.
2) When you compress air, its temperature, pressure, density, and enthalpy change. When you increase the pressure, the volume decreases. This causes impurities, like oil mist and vapors, to become more concentrated in the compressed air. Liquid water can also become saturated. So, the filter for air that is squashed needs to be able to handle really hot temperatures, really strong pressure, a lot of moisture, and a bunch of weight pushing down on it. It might be really hot, like more than 80 degrees Celsius. The pressure could also be very high, like the weight of several atmospheres pushing down at once.
Compressed air filter knots make use of their surface area to control the flow of air. They are usually shaped like a cylinder and have different ways of filtering to make them work better. They are also made to be strong enough to handle pressure.
Different industries and processes use compressed air for different reasons, so they need different levels of filtration and requirements for how clean the air should be. The filter used for compressed filter cartridge has different materials like fiber, ceramic, filter paper, non-woven fabric, sintered metal, etc. because it needs to work better.
When cleaning the compressed air filter, any water and dirt mixed with it will be trapped in the filter cartridge. However, it can't be removed immediately. That's why there is usually a device to drain the water out manually or automatically. People can also check the water level using the view window.
When air is pushed into a filter, it creates pressure which is trapped inside. To know when the filter needs to be changed, a gauge is added to show how much the filter is being blocked. This gauge also tells us how long the filter will last.
In summary, compressed air filters and regular air filters are used for different things and are designed differently.
