Air Dryers
Compare refrigerated, packaged, combination and adsorption dryer options from approximately 4 to 1530 CFM for moisture control, improved air quality and dependable compressed-air performance.
Which Type of Air Dryer Do You Need?
The right dryer depends on the required pressure dew point, compressor airflow, working pressure, inlet temperature, ambient temperature, available space and whether filtration should be supplied separately or as part of the package.

Moisture forms naturally when compressed air cools. Without effective drying, water can contribute to corrosion, damage pneumatic equipment, affect process quality and increase maintenance requirements.
| Dryer Type | Best For | Typical Dew Point Route | Filtration |
|---|---|---|---|
| Refrigeration Dryer | General workshop and industrial moisture control | Commonly around +3°C pressure dew point | Selected separately |
| Refrigeration Dryer Package | Sites wanting a pre-matched dryer and filter arrangement | General industrial drying | Included according to package |
| Combination Dryer | Compact installations with integrated treatment | General industrial drying | Integrated |
| Adsorption Dryer | Very dry air, freezing conditions and sensitive processes | Commonly -40°C, with other options model-dependent | Correct pre- and after-filtration required |
What We Supply
- Standalone refrigerated dryers for general moisture removal.
- Dryer packages with filtration for easier system specification.
- Combination dryers with integrated filters for compact installations.
- Adsorption dryers for low dew point and critical air-quality requirements.
How should an air dryer be sized?
Select from the compressor's actual delivered airflow, then apply the manufacturer's correction factors for working pressure, inlet temperature and ambient temperature.
Why is spare dryer capacity important?
A sensible margin helps the dryer manage warmer conditions, demand peaks, pressure variation and future system growth.
When should I choose an adsorption dryer?
Choose adsorption drying where the required pressure dew point is significantly lower than a refrigerated dryer can provide, or where pipework may be exposed to freezing conditions.
Do I still need filters?
Usually, yes. The required filter arrangement depends on the compressor, dryer technology, final air-quality requirement and whether filtration is already integrated.
Can I size a dryer from compressor motor kW?
No. Dryer selection should be based on actual free air delivery and operating conditions, not compressor motor size alone.
What should be checked before installation?
Confirm airflow, pressure, dew-point requirement, inlet temperature, ambient temperature, electrical supply, ventilation, condensate drainage, connection sizes and service access.
Air Dryer FAQs
What is the difference between a refrigeration dryer and an adsorption dryer?
Refrigeration dryers suit general moisture control, while adsorption dryers are used where much drier compressed air is required.
What airflow range is available?
The overall range covers approximately 4 to 1530 CFM, depending on dryer type and model.
Which brands are available?
The supplied ranges include FSN, Hiline, Tanair, Omega, MOK and MKE products, subject to current availability and model selection.
Can Compressed Air Systems UK install and service air dryers?
Installation, pipework, filtration, condensate management, commissioning, servicing and repairs are available subject to the equipment and site.
Do I need a dryer if my compressor already has a receiver?
A receiver can help with air storage and condensate separation, but it does not replace a correctly selected dryer where controlled moisture removal is required.
Should I choose a dryer package instead of a standalone dryer?
A package can simplify specification where filtration is also required, while a standalone dryer can be more appropriate where existing filtration is already suitable or a custom treatment layout is needed.
