A *3-phase centrifugal air blower* is a heavy-duty blower that runs on *3-phase electricity (415V)* and uses a fast-spinning impeller inside a round housing to push a large volume of air at medium pressure.
Think of it like a big electric fan inside a snail-shell casing that throws air out with force.
How it works
- Motor spins the impeller (fan blade) very fast
- Air enters the center (eye)
- Centrifugal force throws it out through the side outlet
- Result: steady, high-volume airflow
*3-phase* means it's not for normal house socket. It needs industrial power - 3 phase light - so it's more powerful, more efficient, and can run non-stop for hours.
Where they use it in Lagos
- *Blast furnace / blacksmith / foundry* - to blow air into fire
- *Poultry farm* - ventilation, removing ammonia smell
- *Fish farm / aquaculture* - for
