Inline Filter

A reliable source for Inline Filter information and leading Inline Filter Companies & Manufacturers.

An Inline air filter is installed in air purification systems and equipment to protect both the system, and the people relying on them, from damage caused by contaminants, harmful particles, and debris that passes through them. Any contaminants such as pollen, dust, or even viruses may be captured once they enter an air purification system by these filters. Read More…

Inline Filter Inline or line filters are devices that attach to pre-existing ductwork or tubing to remove impurities and liquids from air streams in different systems such as transportation engine filtration, HVAC systems and air compressors. The inline filters are inserted into the systems to protect the receiving equipment from contamination by debris, particles and unwanted materials in the air stream.

These filters are suitable for applications that require constant flow capabilities. Inline air filters are available in various sizes, ranging from miniature to large sizes.

Inline Air Filter

Construction of an Inline Air Filter -

An inline air filter is made of the following components:

  • The Case:

    The case of the inline air filter is made of plastic. Pallets of raw material such as polystyrene, polyvinyl chloride, polyethylene, or polypropylene are injected into the molds to form the case of these filters.

  • An Electric Fan:

    An electric fan is attached to the case in these filters with the help of many screws. The electric fan is used to pull the air through the purifier.

  • Filters:

    Filters are attached to both sides of the case with inline filters. The filters extract the contaminants from the air purification system and help clean the air instantly.

  • Control Switches:

    Control switches are also an important part of inline air filters which are used to control fan speed and also to power on/off the purifier.

Materials Used for an Inline Air Filter -

An inline air filter can be made of many different types of materials such as paper, fiberglass, foam, carbon, aluminum, steel, and plastic. The material of the filter depends on its application and the type of contaminants that it is being used to screen out.

Working of an Inline Air Filter -

A filter is called “inline” if it can be installed anywhere in a compressed air piping system. Inline filters work by trapping solid particles from the compressed air. These particles are contaminants that are captured by these filters by a straining process. The main components and the flow process of air filter is as follows:

  • Inlet (where air enters the filer)
  • Air Path (the flow of air through the filtration system)
  • Filter Baffle (used to direct and restrain the flow of air and contaminants)
  • Filter Discharge (where the filter is removed)
  • Filter Element (the filter material and/or the filter itself)
  • Filter Bowl (places where the water and debris that have been removed are stored)
  • Filter Quiet Zone (a zone at the bottom of the filter bowl where the contaminants are collected)
  • Drain (where contaminants are removed)
Working Of Inline Air Filter

The air enters into the filter using the inlet and is processed through these components. The first step of the filtration process is that the compressed air is passed from the mesh filter. Due to this, a clumping effect is created which traps the larger particles in the filter and converts any liquid into bigger droplets.

Those condensed liquid particles are then moved to the separation chamber. This is the honeycomb-like structure present in the inline filter that allows these condensed particles to get attached and settled on the filter’s pads. It helps in the movement of droplets to the drain. In the end, these droplets are drained through the drain valves. Inline air filters remove bigger particles or contaminants, oil, and water droplets.

Types of Inline Air Filters -

The compressor air filtration system uses a variety of filters and each type has unique characteristics for purifying the air.

Particulate Filters -

Particulates are a mix of extremely small solid particles and liquid droplets. Particulate filters are used to eliminate them from the air by trapping particles that come from the adsorption dryer (used to dry moist air) into the filter material.

Particulate Filter

Activated Carbon Filters -

Activated carbon filters are used in certain environments like petroleum refineries to clean the compressed air of oil droplets. The surface active adsorption of these filters bond with odors, and oils which helps in easy removal.

Activated Carbon Filter

Coalescing Filters -

A coalescing filter is efficient in removing water and aerosols from the compressed air. The smaller droplets are caught easily into these filters, and are converted into bigger droplets. These droplets are then removed from the filter, and are prevented from re-entering through its re-entrainment barrier. It is considered an efficient filter to use for stopping various offenders since it can trap oil, water droplets as well as particulates.

Coalescing Filter

Cold Coalescing Filters -

These filters are operated at low temperatures and are best to use for moisture removal from the air.

Compressed Intake Filters -

Compressed intake filters are the first defense against contaminants. These filters can trap the contaminants up to 0.3 microns and also helps in removal of chemical contaminants from the air.

Compressed Intake Filter

High-Efficiency Filters -

These are highly efficient filters that can remove particulate matter up to 0.01 microns.

High Efficiency Filter

Benefits of Inline Filters -

Inline filters are widely used in many industries such as military, energy, food and beverages, petrochemical, pharmaceutical, and life sciences industries. Inline filters are beneficial to purify the air. These are efficient in trapping particulate matter that can cause many air-borne diseases or contaminate materials and products. Inline filters are to be replaced and cleaned from time to time for better performance and protection.
