Fine Bubble Tubular Diffuser

Specially designed for maximum strength at minimum positive buoyancy. Favoured by the industry due to their large size (90mmX1m, outside diameter) and high air capacity compared to disc diffusers. Significant advantages over disc diffusers include requiring fewer header pipes, less support stands and can be installed quicker. The tube membranes are manufactured with Cold Extrusion Moulding which supports higher flow rates, better tear resistance and lower pressure drops.

Specifications

  • Perforations available on 1mm or 2mm slit length
  • Available in saddle and nipple mounts for British or Metric dimension pipes.
