What is Compressed Air Treatment and Why Is It Important?

Compressed air treatment is a method that involves purifying and dehumidifying the air before it enters the compressor. During compression, air accumulates moisture, oil, and other contaminants that can have a negative impact on equipment performance and product quality.


An efficient and intelligent compressed air system goes beyond high-quality air compressors. It is a combination of a range of expertise and products related to air generation, filtering, drying, condensation, and purification. With an efficient air treatment process, your system will experience extended equipment lifespan, improved operational efficiency, and the preservation of product integrity.


An essential part of compressed air treatment is air quality testing, which guarantees the purity and safety of your industrial process air. It involves the regular analysis and monitoring of compressed air to identify and quantify any contaminants present in the system. Air quality testing uses  specialized equipment and analytical techniques to assess the concentration levels of various contaminants in compressed air.


Regular testing allows for early detection of potential issues, enabling you to take timely corrective measures. This proactive approach helps prevent costly breakdowns, production delays, and product defects, ensuring smooth operations and reducing downtime.

Types of Compressed Air Treatment

Compressed Air Treatment has a diverse range of purposes, compressed air necessitates adherence to distinct quality standards, catering to specific functions. Different methods can be used to remove the moisture content of compressed air. Gardner Denver compressed air types include the following products:

Refrigerated Air Dryer

Refrigerated air dryers account for a majority of the compressed air dryer applications. Quality and efficiency are important for compressed air treatment, and using refrigerated air dryers efficiently provides a continuous supply of dry air. The refrigeration system cools the incoming compressed air, allowing the water to condensate and drain. There are two different types of refrigerated air dryers, cycling units and non-cycling units.

Desiccant Air Dryer

Desiccant dryers (also knows as adsorption dryers) work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapour is removed from compressed air by passing it over an adsorbent desiccant material. As the air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant, however, adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced.

Air Filters

Gardner Denver filters provide dependability in the air system to block any contamination entering the air lines to prevent damage. Keeping out any unwanted dirt or oil is essential for the compressed air system to increase downtime and lower energy costs. Removing moisture, dust and oil from the air will provide the cleanest air for any job.

Condensate Management

Compressed Air Systems should have a condensate management network in place. How a facility manages the air condensate affects the environment. 
Once the compressed air is compressed, the air cools and the excess water condenses into a liquid state. This water mixed with other elements in the environment and traces of lubricant from the compressor create compressed air condensate. The oil must be removed from the condensate before entering the sewer system in an environmentally safe manner. 
Determining the condensate properties that are being produced are valuable when selecting the compressed air system materials.

Process Chillers

A process chiller is a thermal device that removes heat generated from the process. In order to drop the rising temperatures, the equipment repeatedly conducts chilled water running through the system. Removing undesired heat can ensure the process continues in a safe and efficient manner. Chillers are a vital piece of equipment in many processes.

Nitrogen Generators

Nitrogen Generators are the most efficient way to supply gas. Constantly supplying high purity gas, unlike gas cylinders ensures top notch performances. With advanced energy saving technology, the nitrogen gas generators require less compressed air to generate more nitrogen. Between lower costs and reduced downtime, this system provides the most cost-efficient nitrogen supply. 
Our nitrogen generator technology separates the nitrogen molecules from other molecules and removes any traces of oxygen or other gases. Allowing the nitrogen to pass through to the application.

Quick-Lock Compressed Air Piping Various Colors

Compressed Air Piping

The choice of layout, material, and installation of compressed air piping significantly impacts its performance and reliability. To achieve optimal results, the piping should be lightweight, offer high flow rates with low pressure losses, and have smooth internal walls. Quick-Lock and Big-Lock aluminum piping are recommended for industrial applications due to their corrosion resistance and ease of installation. While steel and plastic piping have their benefits, aluminum is favored for its cleanliness and durability.
