DualAir® Fine Bubble Diffuser System

The DualAir® Fine Bubble Diffuser System’s unique design consists of two diffuser bases molded together with a curved saddle formed between them. This design, which is available with either membrane or ceramic media, allows two diffuser assemblies to be mounted at one location.

Dual Air Diffuser

The advanced design of DualAir® high density fine bubble diffuser assemblies provides many advantages over previous systems:

  • they require as few as half as many air diffuser headers, support stands, couplings, end caps, and manifold connections
  • they provide greater contact area between the pipe and the diffuser assembly, thereby providing an attachment bond with greater holding power.  The result is a very economical system that can be installed at 20 to 40 percent less cost


Features and Benefits

  • Up to 40 diffusers per 20 foot air header section
  • Greater contact area for a stronger bond between the diffuser assembly and piping
  • Use of heavy wall diffuser header pipes
  • Design with fewer air diffuser headers
  • Design with fewer pipe supports
  • Design for fewer air manifold to distribution piping concentration
  • Lower shipping costs
  • More open floor space for maintenance
  • Installation time reduced by 20-40 percent
  • Cost effective aeration system
