Oxytube air diffusers

Oxytube tubular air diffusers are especially recommended for the construction of removable aeration systems and in all cases where a large output surface area is required with only a small number of air distribution pipelines.

Tubular air diffusers basically consist of a head with threaded connection, a rigid polypropylene mount and a tubular membrane in elastomer with tiny holes, secured with stainless steel band clamps.

Accessories and components

Membranes made of different materials are available for different applications:

EPDM LP

  • with low plasticiser content (<15%) per reflui civili con apporti industriali e reflui industriali con limitato contenuto di grassi, oli e idrocarburi;
  • maximum operating temperature 80 °C.

SILICONE

  • for industrial wastewater with high fat and hydrocarbon content;
  • maximum operating temperature 100 °C.

Also available for the entire range of tubular air diffusers:

  • stainless steel connectors for installation of diffusers in pairs facing each other on square manifold of 80x80 mm or 100x100 mm
  • adaptors for manifolds with ready-made holes.

Installations

Especially recommended for small/medium sized systems, or in general in all cases where it is not possible to empty the tank for maintenance, these tubular air diffusion systems are built with stainless steel supply assemblies comprising basically a square manifold on which the diffusers are installed in facing pairs, a down-pipe, one or more stiffener tie-rods and a draining system.

  • a square manifold on which the diffusers are mounted in facing pairs;
  • un down-pipe;
  • one or more stiffener tie-rods and a drainage system.


The individual assemblies are simply placed on the bottom of the tank and connected to the main air pipeline with a flange. Stability is ensured by counterweights that also act as feet.
No runner or anchor systems are required. The individual assembles are therefore easy to remove and install with the tank full and in operation.
