Lieferantenwissen · Blowers & Air Delivery
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.
