Hypos gravity aerator LHO aquaculture france

Hypos gravity aerator (LHO)

The Hypos gravity aerator is a fixed device that operates through water flow and free fall. Water passes through perforated stages or ramps, which:

  • increase dissolved oxygen by enhancing air–water contact,

  • remove unwanted gases (CO₂, nitrogen),

  • ensure gentle mixing without stressing the fish.

Equipment operating without electricity, requiring a minimum water level difference of 80 cm. As water passes through the chamber, it is enriched with oxygen while simultaneously degassing. The oxygen content can reach up to 20 mg/l. Includes water flow regulation and adjustable height, made of stainless steel.

Main features:

  • Principle: aeration by trickling and dispersion.

  • Structure: usually stainless steel or resistant plastics.

  • Operation: no motor, very low energy cost (uses gravity).

  • Maintenance: simple, periodic cleaning of grids or ramps.

Applications:

  • Fish farms supplied by pumps or gravity flow.

  • Ponds, tanks, or recirculating systems.

  • Especially suitable for oxygen-sensitive species (trout, salmonids, high-density farming).

An economical, reliable, and silent system, ideal to maintain good water quality and secure fish production.
