Considerations for Selecting a Compressed Air Filter

Considerations for Selecting a Compressed Air Filter

Compressed air is not always immaculate, and it contains minute impurities which need to be cleaned with the help of air filters. In addition, it has a variety of aerosols, vapours that can harm the machinery or other equipment. The filters help in removing all the impurities and enhance the quality of air. Many types of Micro filters are available for various industrial applications; let us discuss in brief:

Compressed air filters are coalescing filters, vapour removing filters, and dry particulate filters.

• Coalescing filter: This filter helps remove water, oil, and aerosols from the compressed air, and the barrier prevents the contaminants from reentering the atmosphere. These filters efficiently remove the contaminants; the particulate levels down to 0.1 microns in size and the liquids down to 0.01 ppm.

Another low-cost alternative for coalescing filters is mist collectors; the collectors do not eliminate the contaminants as the coalescing filters but offer smaller pressure drops (about one psi); this helps systems operate at low pressure, which helps in reducing its operational cost.

• Vapour removal filter: this filter works on the principle of adsorption by using activated carbon granules. They efficiently remove the lubricant aerosols. They can also remove gaseous contaminants that can pass through the coalescing filters.
• Dry particulate filter: these filters remove desiccant particles; they almost work like coalescing filters.

It is also essential to make the correct choice for your industry and choose the air filter to fulfil your requirements the best. Not all compressed air requirements are the same, and every compressed air process requires a different level of purification. For example, the pharmaceutical or food and beverage industries need a higher level of filtration than in the pneumatic industry or filling tires.

It is also essential to know whether the processes you are performing should be completely oil-free or take a small amount of oil. If your application is sensitive to oil, you should install the inline coalescing filter and consider your filters’ energy utilisation and choose accordingly. Lower energy usage leads to fewer power bills which will help you cut some costs.

After installing, many people cannot figure out if they should change their filter or not. Determining whether you should replace your filters depends upon hours of operation, required compressed air quality, or pressure drop.

Ask yourself the following questions when you are confused about if you change your filters or not:

• Is the manufacturer’s service life has expired?
• The air quality is below the accepted grade?
• Pressure drops exceed the determined levels.
• Pressure drop exceeding manufacturer’s levels?

It is also essential to determine the manufacturer who can provide you with standard quality for easy operations for a high-quality filter. For example, Trident is a compressed air filter manufacturer making high-quality products for its customers and helping many industries to produce quality compressed air.
