Disk Diffuser

Disc Diffuser features a unique spilt pattern and slit shapes, which can disperse arr bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. A much highly effective and integrated check valve enables the aeration zones to be easily shutdown for air-on/air-off applications. The membrane disc diffuser can be operated over a wide range of airflows with minimum maintenance for long term performance.

Features
  • Low resistance loss
  • Highly Tear Resistant
  • Ann-clogging, anto-brackflow
  • Ageing-resistant, anti-corrosion
  • High efficiency, energy-saving

Different mambrane material of diffuser
  • 1. EPDM

    Epdm can resist heat, light, oxygen, expecially ozone. Epdm is essentially non-polarity, polarity solution and chemical resistant and chemical resistant, bibulous rate is low, It has good insulating properties.

  • 2. Silicone

    Insoluble in water any solvent, non-toxic and tastlesss, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.

  • 3. PTFE
    • High and temperature resistant, working temperature can be 250C, Good mechanical toughness; even temperature drops to 196C also can keep 5% elongation.
    • Carrosion- resistance to most chemicals and solvents, showing inertia, strong acid resistance, water and various organic solvents
    • High lubrication - the lowest friction coefficient in solid materials
    • Non-adhesion - is the smallest surface tension in a solid material and does not adhere to any substnace.
