Compared with traditional paddle-wheel aerators, microporous tubing aeration saves about 30% of electricity on average, cuts disease incidence in pond fish, shrimp and crab by about 15%, and raises production per mu (667 m²) by 10% for fish, 15% for shrimp and 20% for crab — overall efficiency improves by 20–60%, while survival rate and growth speed also benefit.
Technical points
1. Materials and installation
A microporous tubing system consists of three parts: the blower (main unit), the main air line and the aeration tubing.
(1) Blower. Choose a Roots blower — it offers long service life, high discharge pressure, stable air delivery and reliable operation. Domestic specifications include 2.2 kW, 3.0 kW, 4.0 kW and 5.5 kW models.
(2) Main air line. Two options: galvanized steel pipe or PVC pipe. Roots blowers deliver high-pressure air that runs hot, so most farmers alternate galvanized pipe with PVC sections — safe and cost-effective.
(3) Aeration tubing. Three common types: PVC pipe, aluminum-plastic pipe and micro-porous (nano) tubing. In practice, PVC and micro-porous tubing dominate, each with trade-offs:
- Micro-porous tubing has better aeration performance; drilled PVC pipe distributes air less evenly.
- PVC pipe is easier to source — available at any pipe supplier, from drinking-water grade to electrical-grade.
(4) Installation. Follow the layout sketch supplied with your system.
