ByStudor Handi-Vent™ 4

Compact, High Functioning AAV for Internal Drainage Ventilation

The ByStudor Handi-Vent 4 AAV provides plumbing drainage ventilation to prevent the loss of water trap seals in low rise buildings. It allows air to enter the drainage system, but does not allow foul gas to escape, in order to limit pressure fluctuations within sanitary pipework.

Benefits and features of the ByStudor Handi-Vent 4:

  • Simple push-fit connection to all brands of UK domestic soil pipe (3”/75mm and 4”/110m).
  • Compact size – no bigger than a 4”/110mm soil pipe.
  • High functioning – repeated opening and closing will not affect the sealing operation.
  • Maintenance free – fit and forget.
  • Ideal for the redesign of bathrooms and additional en-suites.
  • CE marked and AII rated to EN12380.
  • Designed to resist extreme temperatures and deterioration.

Produced by Studor, the only specialist manufacturer of drainage ventilation products, the Handi-Vent 4 comes with a lifetime warranty.
