"CRI Jet Aerator, making wastewater greater!"

SUBMERSIBLE JET AERATOR AR-SERIES - JET TYPE AERATION PUMP

CRI Submersible Jet Aerator - AR Series

Features

1. High Efficiency: The AR Series utilizes a direct motor-to-impeller connection, generating strong centrifugal force that enhances water and air mixing, resulting in high oxygen transfer rates.
2. Advanced Impeller Design: The star-shaped closed impeller creates a vacuum that draws in air, ensuring effective mixing and aeration. The impeller is made of cast stainless steel for durability and abrasion resistance​.
3. 360-Degree Aeration: Provides uniform aeration and agitation due to its ability to produce micro-sized bubbles that increase the contact area for oxygen transfer​.
4. Durability: Constructed with materials like CI Pump casing, SS304 motor casing, and SS420 shaft, offering robust performance in various wastewater conditions​.
5. Low Noise: Operates at noise levels below 40 dB, making it suitable for urban and residential areas​.

Advantages

1. High Oxygen Transfer Rate: The micro-sized bubbles generated have a large surface area, ensuring a higher oxygen transfer rate compared to conventional systems​
2. Self-Aspirating: The special impeller design allows for self-aspiration, reducing the need for external air supply systems and making the setup more efficient​.
3. Ease of Maintenance: The design allows for easy maintenance, with the ability to change oil and inspect the motor while the unit remains in its upright position​.
4. Non-Clogging Design: The large inflow port and efficient mixing prevent clogging issues commonly faced in aerators​.

Applications

1. Wastewater Treatment: Effective for both municipal and industrial wastewater treatment plants, including applications in BOD reduction, stabilization, and equalization tanks​.
2. Sewage Treatment: Suitable for sewage and effluent treatment facilities, ensuring efficient aeration and agitation processes​.
3. Agriculture: Can be used in modern irrigation systems for aeration and mixing purposes​.
4. Fish Farming: Ideal for maintaining optimal oxygen levels in aquaculture applications​.
