Our Advantages
(1) Experience the comfort of low noise levels and benefit from cost-effective energy consumption.
(2) Benefit from bottom static aeration, ensuring uniform distribution, ideal for high-density shrimp and fish aquaculture, enhancing both output and quality.
(3) Achieve higher dissolved oxygen content of 6-8 ppm. This accelerates the oxidation of harmful chemicals at the water's bottom, thus improving the living conditions for shrimp and fish and boosting survival rates.
(4) Our system delivers greater aeration quantities and allows for deeper bottom aeration than ever before.
(5) Choose between a complete set Roots blower system or a bare shaft blower to meet your specific needs.
(6) Our products come with the assurance of CE, EAC, and ATEX certifications, guaranteeing unmatched product quality and safety.
