Description

  • To ensure sufficient ventilation, eliminating the need for multiple ventilation caps on the roof.
  • Under normal conditions, the membrane seals the pipe.
  • Effect on:
    • Air pressure: in this case the air pressure on the membrane is low, so no contaminated air can escape.
    • Vacuum: the vacuum created in the pipe pushes the membrane upwards, so that it can let in the necessary air.
  • Important: install vertically.
  • Capacity 2.1 l/sec.
