    Diffuseur Fines Bulles
    High-Performance Aeration

    The key component for optimal oxygen transfer and accelerated sedimentation.

    This professional diffuser with a micro-perforated membrane converts compressed air into fine microbubbles, ensuring oxygen transfer that is up to ten times more efficient than conventional air stones.

    The 5 Key Benefits of the
    diffuseur fines bulles

    • Optimized oxygen transfer
      Fine-bubble technology significantly increases the air/water contact surface area, enabling faster and more efficient oxygenation.

    • Integrated Backflow Prevention System When the compressor stops, the micro-pores close automatically, preventing water and sludge from entering the membrane.

    • Self-Cleaning EPDM Membrane The membrane’s elasticity naturally expels limescale and deposits each time pressure is applied, minimizing clogging.
    • Vertical mixing via the Air-Lift effect
      The diffuser generates an upward current that homogenizes the water layers and reduces stratification.
    • Sustainable design for underwater use
      Made from rot-resistant materials, the diffuser is designed for permanent submersion in demanding conditions.

    • Membrane: High-strength EPDM
    • Connection: 13 mm diameter hose (internal)

    Why choose fine bubbles?

    Oxygenation is a key factor in biological sediment removal and the balance of water bodies.

    Unlike traditional aerators, whose large bubbles rise too quickly to allow for effective dissolution, fine-bubble technology maximizes oxygen transfer in the water column.

    Thanks to a high-precision micro-perforated membrane, the diffuseur Fines Bulles generates thousands of slow-rising microbubbles, significantly increasing the contact time between air and water.

    This optimized oxygenation promotes the activity of aerobic bacteria at the bottom of the water body, accelerating the breakdown of organic matter and the gradual mineralization of the sediment.

    Result: a lasting improvement in water quality and a reduction in siltation.

    Installation Guide

    Proper installation is essential for the diffuser to work effectively.

    1. Essential ballast
      The diffuser floats naturally. It must be secured to a heavy base (stainless steel plate, concrete slab) to ensure it lies flat against the bottom.

    2. Placement Install the diffuser at the deepest point of the water surface.
      To make it easier to retrieve, use a small float and a line to guide it back into place.

    3. Compressor Compatibility The air pump must provide sufficient pressure:
      Approximately 0.1 bar per meter of depth + pressure loss in the hose.
      A compressor with insufficient power will not produce fine bubbles.

    Connection

    Standard professional connectors.

    • Air inlet: male grooved fitting.
    • Compatible hose: technical air hose with an inner diameter of 13 mm (reinforced hose or TASO weighted hose).
    • Safety: Install a stainless steel clamp to prevent dislocation under pressure.

    Don't have a compressor yet?

    This diffuser is a technical component: it requires a suitable air source to operate.
