How to Choose Industrial Filter for Your Compressor?

Your compressed air system’s air isn’t made of naturally clean air. In reality, many of the same vapours, aerosols, and particles that can be found in the natural world are probably present here. There is a good chance that the air contains metal flakes from the pipework. No matter the application, filters are essential for enhancing the air quality within your system. The ideal compressed air filter for your company will rely on your application and a few other important factors. Industrial air compressor manufacturers in our country make different types of industrial filters for compressors and in this article, we will discuss how you can choose the best industrial filter for your compressor.

Factors for Choosing an Industrial Filter for Your Compressor

Standard ratings

Any air filter should follow ISO 8573 guidelines. You could be sued if you don’t follow these rules since it puts you in legal trouble. To uphold the necessary standards, inspect the model you select and purchase from reliable brands. The tiniest particles your filter can capture are indicated by its air filter rating. A typical industrial filter is between five and forty microns. However, there are also additional diameters like 20, 25, and 75 microns available, albeit at lesser frequencies. If your production process is extremely delicate, you can select a filter that can catch particles as small as one micron or smaller.

Flow capacity

Different sized air filters are available, each of which is made to accommodate a particular flow capacity. There is a pressure drop as a result of the capacity that is constantly flowing through your machinery. Therefore, the size of your compressor should be determined by the largest pressure drop over your filter. The amount of electricity required to compress the air grows as the pressure drop rises. Fine-rated filters typically result in an increase in pressure drop. So, unless your activities require detailed filtering, stay away from very fine ratings. The recommended pressure drop for your filter is often no more than five PSIG.

Type of compressor

A centrifugal compressor or a reciprocating rotary screw might be used in your company. There are particular air filters that would suit and function optimally with each type of compressor made by air compressor manufacturers in India. For instance, a coalescing filter will be necessary if you use a rotary screw compressor to remove the oil needed to cool the compressor. On the other hand, since centrifugal compressors don’t use any oil, you don’t typically need to filter out oil vapours.

To help you choose the best filter, your seller or manufacturer could inquire about the compressor you use. As an alternative, consult your original instruction booklet for specifics on the ideal filter. Otherwise, a poor-fitting or inadequately effective filter may be used.

Particle to be filtered

Three different types of air filters are often available: general-purpose, activated-carbon, and coalescing filters. Each category deals with a certain contamination type:

  • General-purpose FIlters- These eliminate solid contaminants including dust and rust scale.
  • Activated carbon filters- These utilise charcoal’s carbon to absorb lubricating gases and vapours.
  • Coalescing filters- These eliminate tiny particles, including paint fluid, water, and oil.

Type of operation

Compressor filters are used in numerous industrial applications. The sort of filter that is best for you depends on your line of work and the accompanying toxins. Additionally, filters always capture particles during each use. As a result, you eventually need to clean and replace the filters. When your compressor runs for extended periods of time, more pollutants are trapped. You will therefore need to clean the filter more frequently.
