The Atlas Copco F series refrigerant dryers keep your compressed air system in optimal shape, removing humidity efficiently and reliably. With a stable pressure dewpoint as low as 7 °C, these compact, low-maintenance dryers are compatible with most compressor technologies and applications.

The compressed air you use must be clean and dry. Moisture can cause corrosion in pipe work, premature failure of pneumatic equipment, or product spoilage. Based on direct expansion technology with cycling, non-cycling and Variable Speed variants, Atlas Copco’s FD Refrigerated Air Dryers remove moisture from compressed air with a dew point as low as +3°C/+37.4°F. They are highly energy-efficient, easy to install, and among the most environmentally friendly and quietest in their class. Most importantly, they deliver dry air to protect your air system and finished products.

Capacity FAD (cfm): 13 – 8480 cfm
Working pressure: 189 – 203 psig
Pressure Dewpoint 37 – 41 °F

Customer benefits

High Reliability – Atlas Copco’s FD Refrigerated Air Dryers eliminate system failures, production downtime and costly repairs by removing moisture from compressed air with a pressure dew point as low as +3°C/+37.4°F. Separate components undergo severe endurance tests while the unique design of the heat exchanger significantly improves dryer lifetime. Advanced control functions ensure dry air at all conditions and prevent freezing at low loads.

Maximum Energy Savings – Atlas Copco’s FD Refrigerated Air Dryers incorporate energy-saving features that cut your carbon footprint. Incorporating unique heat exchanger technology and Saver Cycle Control, the FD ensures a low pressure drop of typically below 0.2 bar/2.9 psi and minimal energy consumption. Integrated Variable Speed Drive (VSD) technology variants offer even further energy savings by automatically tuning the energy input to the precise demand. The FD offers an extremely low total cost of ownership.

Easy Installation – FD air dryers have a small footprint thanks to an innovative all-in-one design. Delivered ready for use, installation is straightforward, minimizing costly production downtime. On some models, in- and outlet connections are positioned on top of the unit, enabling installation against a wall.

Environmentally Friendly – Enclosed in a sound suppression canopy to reduce noise levels, FD air dryers stand out by being among the most environmentally friendly and quietest in their class. They fully comply with ISO 14001 standards and Montreal Protocol regulations, and use CFC-free refrigerants to prevent any damage to the earth’s ozone layer. FD air dryers have an ozone depletion potential of zero.
