Aquaculture Blowers — Regenerative, Rotary Lobe, Centrifugal
Blowers deliver low-pressure air for aeration, CO₂ stripping and biofilters. Under-sizing kills fish quickly; over-sizing wastes lifetime energy. Efficiency (kWh per Nm³) is the single most important selection metric after reliability.

Typical applications
- Diffused aeration in ponds and tanks
- CO₂ degassing towers in RAS
- Biofilter fluidisation
Project sizes
- Small farm: 1–10 kW blowers
- Commercial: 30–500 kW blower rooms
Selection criteria
- kWh/Nm³ at design duty point
- N+1 redundancy at farm level
- Noise and vibration for indoor rooms
- Cool-air intake and heat-recovery option
Questions buyers should ask
- Provide efficiency curve at my altitude and temperature
- What is the guaranteed lifetime on bearings?
- What is the noise level at 1 m?
Common procurement mistakes
- Sizing blowers on nameplate not duty point
- Ignoring altitude derating
- Skipping N+1
RFQ recommendations
- Tender against a duty point and altitude, not a model number
- Include VFD, silencers and heat recovery
