Aquaculture Aeration Equipment
Complete aquaculture aeration equipment from one factory: roots blowers, microporous tubes and discs, floating aerators and galvanized canvas ponds. Every piece of aquaculture aeration equipment between the blower room and the pond bottom — matched, tested and shipped as a set.
What we manufacture
How to choose aeration equipment in 3 steps
- Size from the pond, not the catalogue. Area, depth and stocking density set the oxygen demand. For ponds 1-2 m deep the baseline is microporous tubing laid 10-20 cm above the bottom with runs 3-5 m apart — 60-100 m of tubing per mu (667 m²).
- Match the blower to the tubing. Roughly 1 kW of blower per 100-150 m of tubing, with the pressure rating covering water depth plus line losses. Sizing on pond area alone is the mistake we see most often on farms.
- Decide the drive and the power source. A standard induction motor with an external VFD costs less up front; a permanent-magnet motor cuts running cost where tariffs are high. Off-grid ponds add solar at about 1 kW of panel per kW of blower.
Parts of a pond aeration system
A complete system is a matched set rather than four separate purchases: the blower and its enclosure, the main air line and valves, the microporous tubes or discs at the pond bottom, and the control panel with protection. Ordering them as one design is what keeps the air volume at the diffusers once the depth and the line losses are accounted for.
Buying direct from the factory
Jiangyin Zhongxin Machinery Equipment Co., Ltd. is an industrial aeration system manufacturer based in Jiangyin, Jiangsu, China. We build the roots blowers, the microporous tubing and diffusers, and the floating pond aerators ourselves in our own workshops — so a pond aeration system is matched as one design, not assembled from three different suppliers.
- OEM & ODM: Custom voltage (220 / 380 / 460 V, 50 or 60 Hz), freshwater or seawater-rated materials, your brand on the nameplate and packaging.
- MOQ & samples: MOQ depends on the model and how far the customization goes — quoted per order; sample units are available for evaluation on standard configurations.
- Lead time: Quoted per configuration and quantity, and counted from the point the specification is frozen.
- Trade terms: FOB (Shanghai / Ningbo) and CIF supported; export documentation handled in-house.
- Engineering support: Send pond area, depth and stocking density — we size the pond aerators or the blower-and-tubing system for you. Off-grid ponds run the same equipment on solar and battery supply: a solar pond aerator setup is sized at roughly 1 kW of panel per kW of blower, as set out in our off-grid solar aeration guide.

Buying direct: common questions
Can you customize the voltage for my country?
Yes. Motors are wound for 220 / 380 / 460 V at 50 or 60 Hz and the control panel is configured for the same grid. Tell us the voltage, phase and frequency at the quotation stage — a mismatched or rewound motor runs hot and loses performance, so this is decided before production, not at shipping.
Do you offer OEM / private-label production?
Yes, both OEM (built to your drawing or specification) and ODM (our existing designs adapted to your market). Nameplates, model coding, cartons, manuals and float colours can carry your brand, and the branding details are fixed at the sampling stage so the first batch matches what you sell.
What is your MOQ and lead time?
Both depend on the model and the level of customization, so they are quoted per order and confirmed in writing rather than published as fixed figures. Standard configurations can usually be sampled; customized SKUs need a minimum batch because of tooling and material minimums. Lead time runs from the moment the specification is frozen.
How do I verify a factory before placing an order?
Ask for the plant address (city and province, not just "China"), a video of the production process for the product you are buying, the list of parts made in-house versus bought in, a pressure/airflow record at your duty point, and references at your scale. We are the manufacturer rather than a trading company, so these answers come with data — and a video call through the workshop can be arranged during your due diligence.
Not sure which blower fits your pond?
Tell us the pond area, depth and species — we will recommend the layout and send a quote.
