Do you have or need dryers for compressed air for your facility? If so, you may be confused about the different types of air dryers that are available to you. As a provider of quality air compressor and air dryer products, Fluid Aire Dynamics can get you just about any air dryer you need for your business.
Here is some basic information about commercial, industrial & construction air dryers, and how they work, to help you determine what your own air dryer needs are.
What Are Compressed Air Dryers?
Compressed air dryers are machines that remove water vapor from compressed air. They are necessary with air compressors because air compressors concentrate various elements of the air, giving it a higher dew point and creating condensation that could negatively affect your facility, causing freezing, corrosion and other problems.
How Do Compressed Air Dryers Work?
Different types of compressed air dryers work in different ways. There are refrigerated air dryers, desiccant air dryers, membrane air dryers and deliquescent air dryers. Which type you use will depend on what your specific application needs are.
What Type of Applications Are Appropriate for Compressed Air Dryers?
You can find compressed air dryers in use for many applications across multiple industries, including:
- Nuclear Power
- Food and Beverage
What Are the Different Types of Compressed Air Dryers?
Refrigerated dryers are commonly used air compressor dryers that work with twin heat exchangers in order to cool down the hot air as it comes in and prevent it from condensing again.
Oftentimes the most cost-effective drying option, refrigerated dryers have wide application in most manufacturing facilities as they provide a level of dryness that satisfies most compressed air uses. Fluid Aire Dynamics is proud to offer some of the best products available in the marketplace.

You can use desiccant dryers when you are working with extremely sensitive products that cannot tolerate any moisture. Desiccant dryers use active desiccant material, like activated alumina, silica gel or molecular sieves, to remove water from the compressed air through adsorption as the air cycles through the machine.
These dryers can be heatless, as the desiccant material draws the moisture and a pressure-swing system regenerates it, but they can also be heated. This is sometimes known as a “heated purge dryer” or “blower purge dryer,” since it uses hot air blowers to purge the desiccant material so that it can absorb moisture effectively again.
If you have an oil-free air compressor, you may be able to utilize a Heat of Compression desiccant dryer, which uses the energy of the compression process to regenerate the desiccant.
For applications demanding ultra-dry compressed air, desiccant dryers are often the product of choice. As with refrigerated dryers, Fluid Aire Dynamics offers a wide range of models to suit any price or performance requirement.

Breathing Air Purifiers
High quality air is of vital importance to industrial facilities, but nowhere is it as critical as in breathing air applications. The purity of breathing air is crucial to assure worker safety in a wide range of applications including tank cleaning, sand blasting, paint spray and many others. Fluid Aire Dynamics can solve these critical breathing air applications with products from top quality manufacturers.

Membrane dryers are dehumidifying dryers that work by depressing the dew point of incoming air. They are popular since they can operate continuously without electricity and are quiet and low-maintenance.
No longer relegated to simply point-of-use drying applications, membrane dryers are now available in capacities and efficiencies that rival desiccant dryers without the costly and time-consuming maintenance. They are ideal for applications where the dew point requirement falls somewhere below +32°F (0°C) and -40°F/C.
