Product Description
In high-density aquaculture, the dissolved oxygen level directly
determines the survival rate, growth speed, and breeding benefits
of fish and shrimp. The **vpsa oxygen generator** (Vacuum Pressure
Swing Adsorption Oxygen Generator) is the core equipment to break
through the "oxygen deficiency bottleneck". As a professional
**pressure swing adsorption oxygen plant**, it is based on vacuum
pressure swing adsorption technology, which separates air
selectively through molecular sieves and produces high-purity
oxygen without chemical reagents. Compared with traditional
oxygenation equipment, its energy consumption is reduced by more
than 40%. This 80Nm³/h model with 95% purity is specially designed
for aquaculture. It can quickly increase the dissolved oxygen in
water to 8-12mg/L, perfectly meeting the high-density breeding
needs of fish, shrimp, crab and other species, and fundamentally
reducing the risks of "surface floating" and "pond turnover".

Why is the VPSA Oxygen Generator More Efficient Than Traditional
Oxygenation Equipment?
Traditional aquaculture oxygenation relies on equipment such as
aerators and impeller oxygenators, with an oxygen dissolution
efficiency from air of only 15%-20%. However, the 95% high-purity
oxygen produced by the **psa system for oxygen** (Pressure Swing
Adsorption Oxygen System) can reach an oxygen dissolution
efficiency of over 85% through nanobubble devices. Taking an 80-mu
grass carp aquaculture pond as an example, traditional equipment
requires 10 units of 15kW impeller oxygenators to work
simultaneously, while the 80Nm³/h VPSA oxygen generator only needs
35kW to stabilize the dissolved oxygen in water at 10mg/L. It not
only saves 60% of electricity but also reduces the stress response
of fish and shrimp, increasing their growth rate by 12%-15%.
Compared with the **psa oxygen generator** (Pressure Swing
Adsorption Oxygen Generator), its **VPSA Oxygen System** reduces
energy consumption through vacuum regeneration, making it more
suitable for the long-term operation needs of aquaculture.
Adapting to Different Aquaculture Scenarios: Flexible Application
from Ponds to Industrial Systems
The adjustable oxygen output design of this VPSA oxygen generator
enables it to adapt to multiple aquaculture scenarios: in pond
aquaculture, it can deliver oxygen directly to the bottom of the
water through floating aeration discs, solving the problem of
oxygen deficiency in the bottom layer; in industrial recirculating
aquaculture, it links with ozone generators to not only improve
dissolved oxygen but also assist in water purification; in shrimp
and crab breeding farms, the 95% oxygen purity can accurately
control the dissolved oxygen in the breeding pond at 12mg/L,
improving the survival rate of larvae. Compared with the **vsa
oxygen plant** (Vacuum Swing Adsorption Oxygen Plant), it can still
maintain stable purity during low-power operation, making it
suitable for intermittent high oxygen consumption scenarios such as
nights and rainy days, avoiding energy waste.
Key to Selection: Choose Aquaculture-Specific **PSA Oxygen
Generator Manufacturers**
Oxygen generators for aquaculture need to adapt to high-humidity
and salt-spray-rich environments. Therefore, it is necessary to
select **psa oxygen generator manufacturers** (PSA Oxygen Generator
Manufacturers) with experience in aquaculture scenario design.
Three key points should be checked during selection: first, whether
the equipment uses corrosion-resistant materials, and whether the
components in contact with oxygen and water are made of 316
stainless steel to avoid seawater corrosion; second, whether it is
equipped with a dissolved oxygen linkage control system that can
automatically adjust oxygen production according to real-time
dissolved oxygen data, reducing manual operation; third,
after-sales response capability, requiring manufacturers to have
service outlets in aquaculture-concentrated areas to ensure on-site
maintenance within 4 hours in case of equipment failure. In
addition, priority should be given to manufacturers with
cooperative cases with provincial aquaculture technology promotion
stations to ensure the equipment complies with aquaculture
technical specifications.
In conclusion, the 80Nm³/h 95% purity **vpsa oxygen generator** has
completely transformed the oxygenation model in aquaculture with
its advantages of high efficiency, energy saving and flexibility.
Through **pressure swing adsorption for oxygen production**
(Pressure Swing Adsorption Oxygen Production Technology), it not
only solves the oxygen deficiency problem in high-density
aquaculture but also improves farmers' benefits with controllable
operating costs, becoming an indispensable core equipment in modern
aquaculture.
