Disc Air Diffuser
Disc Air Diffuser
Introduction
The disc air diffuser is an aeration system with mature technology, reliable operation and excellent performance. The disc air diffuser assembly consist of a microporous membrane with integral gasket, diffuser holder, air flow orifice and a retaining device.
The air bubbles size varies from 0.5 mm ~ 1.5 mm depends on the applied air pressure & the installation depth.
-
The disc air diffuser featuring by its small air bubbles size, uniform diffusion, clog free, anti backflow with high membrane elasticity & erosion resistant.
-
The unique disc structure design and the selection of high quality construction materials, makes the diaphragm difficult to tear and assure a long service life.
-
The connection of the disc air diffuser is leak free due to the double gaskets installed at the diffuser external thread and the support internal thread.
-
The membrane is made from high quality raw material, seamless and resistant to dry operation, assuring 10+ years life service.

Customized Suspended Air Diffuser
Introduction
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.
Features
01
Air supply from both ends of the tube, High oxygen utilization, large service area and low energy consumption.
02
The rubber film is CNC punched, identical holes size, assuring sustainable and high performance, clog and tear free.
03
The suspension system can be designed in order to inspect part by part and for maintenance without aeration shutdown.
04
High oxygen transfer, assuring the decomposition of the pollutants in the wastewater.
05
Special swinging effect during aeration to clean the pool bottom from settled sludge and to improve the oxygen utilization.
06
Onsite friendly & easy maintenance.
