Customized Suspended Air Diffuser
The suspended air diffuser is a tubular customized type, based on customers needs, water quality and the application. The material of construction of this type of diffusers can be made from EPDM or Silicone, UPVC Tube and SS304 or SS316 fasteners cables and clamps.
This type of aerator is suspended by cables, with high flexibility in case of maintenance in terms of pulling up and re-submerging.
The frame is made from stainless steel to keep the aerator at the bottom of the pool and to prevent floating effect.
The air supply is normally connected to two ports with Ø32 mm.
