Low Dew Point Combined Compressed Air Dryer FAG Series for PSA Pretreatment
Product Summary
The FAG Series combined low dew point compressed air dryer integrates a refrigerated dryer and an adsorption dryer into one unit. It delivers pressure dew points down to -60℃ ~ -70℃, meeting the demanding requirements of PSA oxygen generator, PSA nitrogen generator, and membrane gas-separation plant pretreatment. With a rated air treatment flow of 1~300Nm³/min and working pressure of 0.6~0.8MPa (0.8~3.0MPa optional), it is engineered for continuous industrial operation.
Key Selling Points
- Low regeneration air loss of only 3~6% reduces operating costs and energy consumption.
- Microcomputer control with LCD/LED display provides real-time equipment status and multiple fault alarm functions, enabling proactive maintenance.
- Optional RS485/RS232 communication, linkage interface, and dew point detection facilitate integration into centralized monitoring systems.
- Reasonable structure design simplifies operation and maintenance, minimizing downtime.

Models and Options
FAG Series covers a wide flow range from 1 to 300 Nm³/min. Optional high-pressure version up to 3.0 MPa is available for special applications. Choose air cooling or water cooling based on site conditions.
Materials and Structure
Standard construction uses carbon steel; stainless steel (SS304) is available as an option for corrosive environments. The integrated structure combines refrigeration and adsorption drying stages in a single skid, saving floor space and simplifying piping.
Applications
- Pretreatment for PSA oxygen generator, PSA nitrogen generator, and membrane gas-separation plant
- Lithium-ion battery production, photovoltaic silicon-wafer and solar-cell manufacturing
- Semiconductor wafer handling, SMT soldering, printed-circuit-board workshop
- Optical-fiber preform and high-precision optical-glass processing
- Central air-supply for multi-unit laser-cutting, laser-welding and metal-annealing lines
Customization
Customization options include stainless steel construction, ATEX certification, ASME code compliance, and CE marking to meet regional and industry standards.
FAQ
Q: What is the minimum dew point achievable?
A: The qualified air dew point is ≤ -60℃ ~ -70℃, suitable for most high-purity gas applications.
Q: Can the dryer handle high inlet temperatures?
A: The maximum inlet temperature is <38℃. For higher temperatures, a pre-cooler or chiller may be required.
Q: What are the available cooling methods?
A: Air cooling and water cooling are both available; selection depends on the site's cooling water availability and ambient conditions.
Q: Is remote monitoring supported?
A: Yes, optional RS485/RS232 interfaces and dew point detection allow remote monitoring and control.
Q: Can the unit be customized for high pressure?
A: Yes, working pressure up to 3.0 MPa is optional.
Q: What regeneration air loss can be expected?
A: The regeneration air loss is as low as 3~6%, reducing energy waste.
Q: What materials are available?
A: Standard carbon steel or optional SS304 stainless steel.
Q: Does the dryer comply with international standards?
A: Yes, customization options include ATEX, ASME, and CE certifications.
