Air Compressor Inline Filters

Inline air compressor filters form an integral part of the compressed air process. Their core function is to prevent the passage of oil and particulates from compressed air tools into your system. When these contaminants – dirt, dust, or loose metal particles resulting from pipe corrosion – enter your system, they can impact quality control, disrupt production lines, and consequently, affect customer satisfaction.

Choosing the right inline air compressor filter is key to preventing damage to the final product, especially if your process is sensitive to impurities. These filters, depending on your specific needs, can be strategically placed anywhere in the piping system, such as directly after the air compressor, before and after the compressed air dryer, or prior to the point of use on each compressed air drop.

Dry Particulate Filters 

Dry particulate filters are integral for removing desiccant particles after an adsorption air dryer. They act as a sieve, preventing dust and particles from causing clogs by filtering through a membrane material. This membrane essentially functions as a gate, only allowing air to pass through while blocking larger contaminants.

Coalescing Filters 

Coalescing filters play a vital role in capturing oil, aerosols, and tiny moisture droplets to prevent condensation in the system – essential for eliminating rust. The separation is a two-phase process. Smaller droplets merge with larger ones, enabling their removal from the filter. A re-entrainment barrier then prevents these droplets from re-entering the air.

Vapour Removal Filters 

Vapour removal filters are designed to extract gaseous lubricants that make it through the coalescing filter. However, these filters are not suitable for capturing lubricant aerosols as they could saturate the filter and render it ineffective within hours. To avoid this, a coalescing filter should precede a vapour removal filter. These filters employ activated charcoal as the filtering medium in the adsorption process.

0.01-Micron

A 0.01-micron air filter can separate residual oil and extremely small particles down to 0.01-micron. It produces air which is free from oil. Is used for the protection of a control system, pneumatics haulage, painting systems or as a post-filter for adsorption dryers.

1-Micron

A 1-micron filter is capable of separating particles such as liquid and oil down to 1 micron. It is normally used on air dryers as a pre-filter. 1-micron filters can prevent the deterioration of your air compressor piping, for surface treatment, on vacuum pump exhausts, on compressed air motors, and as pre-filter for air dryers.

The recommended frequency for changing air compressor filters is once a year, or every 8,000 hours of operation. However, certain factors might necessitate more frequent changes. These include improperly sized filtration, high oil carryover from compressor equipment leading to quicker filter saturation, and increased particulates due to pipe or equipment corrosion.

Our range of inline compressed air filters at Express Australia not only bolsters the performance of your machines but also enhances energy efficiency, translating into significant savings on power usage.

Our expert team at Express Australia stands ready to assist you with installation and maintenance. We are equipped with the knowledge to advise on which type of inline air filter will serve your compressed air product best. Reach out to us today to optimise your system’s performance and longevity.

Inline air compressor filters offer a distinct advantage due to their strategic placement within the compressed air system. Unlike standard filters, inline filters can be installed directly in the air line path, offering versatile and efficient contaminant removal regardless of the system’s layout. They are specifically designed to filter out impurities such as oil, water, and particulates directly from the compressed air stream without impeding airflow, ensuring a steady and clean power supply.

In addition to their practical configuration, inline filters are recognised for their durability and maintenance ease. They can handle high pressure and extreme conditions, extending the lifespan of your compressed air system and reducing overall maintenance costs. These filters also offer superior filtration precision, with models available to filter particles down to 0.01 micron, ensuring maximum protection for your tools and equipment. As such, inline filters are an indispensable asset in maintaining the purity and efficiency of your compressed air system.
