Diffuser

LTD-144 Disk Diffuser

Description
Feature
  1. Pipeline Caliber for Connection:
    PT1B thread.
  2. 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.
  3. Excellent corrosion resistance, constructed with a state-of-the-art ABS compound, boasting outstanding temperature resistance.
  4. Long-lasting (three times the life-span of ordinary rubber)
  5. Oil and corrosion resistant valve.
  6. Fully-closed against backflow.
  7. 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.
