4.1.3 Power air-pump
To produce aeration in large and deep aquarium or a battery of aquaria, such as those installed in public aquaria, more powerful electric motor driven piston-pumps or rotary pumps are used. They are more efficient due to high output and noiseless running. However, they are expensive and need care and maintenance more frequently. |
