Product Description

PSA Oxygen Generator

eWater is known for building standard, economically priced oxygen generation systems that can be customized as needed. Our oxygen generators can be integrated with a compressor and oxygen cylinder filling station up to 92% purity within a box structure for easy shipping and on-demand, low-cost oxygen generation.

The unnecessary oxygen can be stored up in the tank first and the oxygen generator will stop running when the tank is filled. To meet your specs, we can manufacture a highly efficient generation system for separating oxygen gas from the air, completely enclosed within a containe


I. Adopting German technology, the oil-free compressors ensure adequate supply of source air with large air output
II. Using CECA medical grade molecular sieve and advanced packaging technology, the oxygen concentration can reach up to 90% purity without decay after 5 minutes
III. Dual cooling system is designed to improve the performance of the heat dissipation in an all-weather condition.
IV. The concentration monitoring technology has been developed to monitor the oxygen concentration on line
V. Multi-grade noise reduction devices are integrated and the noise is less than 50 db

VI. With the multiple early-warning systems such as pressure-low warning, failure warning, overload and concentration errors warning, the equipment is safe and reliable
VII. Maintenance-free operation

RAS Process

RAS Water Treatment Processes

A series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps are often done in order or sometimes in tandem. After leaving the vessel holding fish the water is first treated for solids before entering a biofilter to convert ammonia, next degassing and oxygenation occur, often followed by heating/cooling and sterilization. Each of these processes can be completed by using a variety of different methods and equipment, but regardless all must take place to ensure a healthy environment that maximizes fish growth and health. 

Drum Filer

Be used for the Solids Filtration

Able to remove 42%~75% of the total particales from the aquaculture water vlume.


Be used for the Oxygenation

High performance&durable, with high oxygen utilization rat

Specialized design for high density farming.


We can give our customers timely feedback on the problem encountered by our customers with on-site generators.
