Coarse Bubble Disc Diffuser

• Pipe Caliber for connection
• Hard enduring diffuser can decrease pressure loss
• Hard enduring diffuser with excellent corrosion resistance
• Full-close against backflow

Pipeline Caliber for Connection: PT1B thread.
Limits pressure losses: The flexible valve enables precise adjustment of the pressure discharge force with the use of an air volume gauge, leading to fewer pressure losses.
Excellent corrosion resistance, constructed with a state-of-the-art ABS compound, boasting outstanding temperature resistance.

Long-lasting (three times the life-span of ordinary rubber).

• Oil and corrosion resistant valve.
• corrosion resistant valve.
• Fully-closed against backflow.

Should the pump be stopped, a specially constructed valve is designated to provide a complete seal between the cut-out air flow from underneath and the water pressure above. This naturally prevents any undesired backflow of water into the apparatus.
