Air compressors are used in a variety of industries with a wide variety of filter choices
Compressed air is not inherently clean, nor is the environment around it. The air in compressor systems is full of all kinds of particles, aerosols and vapors that can contaminate the final process and product, and damage machines and other equipment.
Therefore, the choice of air filter is important. In addition to choosing the right air compressor, an aftertreatment system is also important to improve the compressed air quality with a powerful filter system while increasing system efficiency. The number and type of filters required for an air compressor depends on the compressor application or the air quality required for the process.
Types of compressed air filters
What is a compressed air filter? Compressed air filters are additional compressed air equipment that help remove unwanted and potentially harmful contaminants from compressed air. As mentioned above, these can be aerosols, particles or vapors. Particles are small solid particles such as dust, dirt, metal particles from corrosion of pipes, and pollen. Aerosols are small droplets of liquid (ie oil or water, depending on the type of compressor), and vapors are liquids that have been converted to gases.
There are four types of compressed air filters:
coalescing filter, vapor removal filter, dry particulate filter, catalytic oxidation oil removal filter. Both types ultimately achieve the same result (removal of contaminants), but the four types work in different ways. coalesce filter
Coalescing filters remove water, oil and aerosols from the air while preventing contaminants from re-entering the air. These filters remove particles from compressed air and trap them in filter media, which can cause pressure drops if not replaced regularly. Coalescing filters successfully remove most contaminants, reducing particle concentrations to 0.1 microns and liquid concentrations to 0.01 ppm.
vapor removal filter
Extraction filters work according to the adsorption principle. They typically use activated carbon particles, carbon cloth, or paper to remove lubricant aerosols. A vapor removal filter works well after a coalescing filter because it traps and removes gaseous lubricants that pass through the coalescing filter. dry particle filter
A dry particle filter is typically used to remove desiccant particles after the desiccant dryer. Dry particle filters work in the same way as coalescing filters.
Oil removal filter for catalytic oxidation
Catalytic oxidation oil removal filter is used to remove oil pollution impurities in compressed air by the catalytic action of catalyst, usually a special filter for oil pollution in compressed air, oil pollution removal is 0 degree Can reach the oil-free state, is now a more mature oil removal technology.
Now that I understand the types of air compressor filters, which one is right for my existing compressor? Should I replace the existing filter? Which filters are suitable for air compressors?
Applying compressed air is not the same as applying compressed air! Different applications require different degrees of filtration. Therefore, in order to choose the right type of filter for your compressor, you need to understand the specific application of your air compressor. For example, the compressed air used in pharmaceutical energy processes requires a higher quality of compressed air than the compressed air used to power pneumatic tools or inflate tires.
Also, consider how important the energy efficiency of your device is. Less energy consumption means lower electricity bills. High-performance filters can produce very clean air (such as removing particles smaller than 0.01 microns) while minimizing pressure drop.
When the filter needs to be replaced depends on how long the air compressor has been running and the quality of compressed air required.
A drop in pressure may also indicate that the filter needs to be replaced. Consider the following questions when considering whether to replace your compressed air filter:
> Has your device reached its end of life?
>Do air audits show that air quality is below acceptable limits?
>Is the pressure drop above the acceptable level?
>Does the pressure drop exceed the switch point specified by the manufacturer? If any of the above questions are met, it means you need a new filter (Note:
The problem of catalytic oxidation type oil removal filter, catalytic oxidation type oil removal device, the catalyst is applied as the core material, the catalyst only plays the role of catalyst, does not produce consumables, no cartridges and other consumables No need to replace. Therefore, removing the oil is very easy), many would consider replacing the filter cartridge before the proposed pressure drop or air quality problem occurs.
