Types of Compressed Air & Gas Coalescers

Graver Technologies offers a range of compressed air and gas coalescers designed to meet various industrial needs. Our collection features various AGS Series Air & Gas Coalescers, which feature a high-efficiency pleated fiberglass media supported by a carbon steel core, with stainless steel internals available for corrosive environments. A polyester foam outer wrap aids in liquid drainage and prevents re-entrainment. The pleated design offers a large surface area, providing high dirt-holding capacity and extended service life. Fine liquid droplets coalesce into larger ones, which drain by gravity to the sump for removal. With an operating pressure of up to 180 psig, these filters offer efficient, long-term performance in demanding applications.

‍AGSH Series Coalescing Filters: These coalescing filters are designed for high-efficiency removal of dispersed liquid and solid particles .3 microns and larger from air and gas streams. These coalescer air filters are designed for pressures of up to 285 psig. They are suited for protecting equipment in gas pipelines from liquid and solid contaminants.‍
AGSHH Series Coalescing Filters: These coalescing filters possess all the features of the AGS Series and are equipped with automatic drain valves, which ensure automated drainage of the coalesced liquid, shutting down the system. These coalescer air filters are designed for pressures of up to 740 psig.

Frequently Asked Questions

What is the difference between compressed air & gas coalescers vs. compressed air & gas filters?

The compressed air & gas coalescers and compressed air& gas filters are misunderstood for the same. However, they differ in design, function, and the type of contaminants they remove from compressed air or gas systems. Here are the differences:

Main Function

Compressed air and gas coalescers are designed to remove liquid contaminants, such as oil mist or water droplets from compressed air or gas. They capture tiny liquid droplets and merge them into large droplets that can be easily removed.
Compressed air and gas filters remove solid particulate components, such as dirt, dust, and debris from the compressed air and gas flow. These filters can capture particles in different sizes.

Media Type

Coalescer filters use multi-layer or fibrous media made from pleated synthetic fibers to capture and merge liquid contaminants. The media helps promote the merging of liquid droplets into large ones. The coalescing media creates a surface, encouraging the formation of liquid droplets, which accumulate and separate from the air or gas flow.
Compressed air and gas filters feature porous, pleated, or mesh filter media that traps solid particles. Sintered metal, activated carbon, cellulose, and woven or non-woven fabrics are materials used to make these filters. The media is distinguished by its rigid structure, with pore sizes – 1 micron, 5 microns, and more, which determine the filtration level.

Contaminants Removed

Coalescer filters remove liquids and finer liquid aerosols. They are employed in applications where moisture removal is critical, such as in pneumatic tools, manufacturing processes, and painting applications.
Compressed air and gas filters remove solid particles and sometimes large liquid droplets, which is why they are employed in applications where achieving purity of air is essential.

Design and Construction

Compressed air and gas coalescers feature multistage designs where the first stage removes larger droplets. The second stage refines the process to capture aerosols and small droplets. The filter element is packed densely to allow the coalescing action.
Compressed air and gas filters may have single-stage or multi-stage design depending on the level of filtration required and application. They use a combination of media for entrapping particulates.

Where compressed air coalescers are typically installed?

Compressed air coalescers are usually installed at the point of entry into the air system, such as at the compressor outlet, or at critical points along the air line where contamination control is necessary. They are placed before any sensitive equipment or pneumatic tools to ensure clean and dry air is supplied to the system.

How often should compressed air coalescers be replaced?

The frequency of replacement depends on several factors, such as the level of contamination, air quality, and the specific demands of your system. Generally, the filter elements should be checked regularly and replaced every 6 to 12 months, but high-contamination environments may require more frequent maintenance. Always refer to the manufacturer’s guidelines for optimal performance and replacement intervals.

How does a coalescing air filter work?

A coalescing air filter works by using a specialized media to capture and combine (coalesce) small droplets of oil, water, and other contaminants present in compressed air. The contaminants are filtered out and accumulated in the filter element, while clean, dry air passes through to the system. This ensures that the air remains contaminant-free, protecting downstream equipment and maintaining system efficiency.

How often should compressed air filters be changed?

The frequency of changing a compressed air filter depends on the system's operational conditions and the contaminants present. Typically, filters should be replaced every 6-12 months to maintain optimal compressed air filtration efficiency. Regular inspection helps to determine when it's time to replace the filter to prevent system inefficiencies.
