The complete range of Manthorpe GTV in-line tile vents are suitable for conversion into service terminals for use in mechanical extraction as well as soil ventilation. In order to convert a GTV in-line tile vent into a service terminal, you will need a GTV-AD tile vent adaptor which converts the rectangular outlet spigot on the back of the tile vents into a 100mm (4") diameter pipe opening. The GTV-AD tile vent adaptor has an internal diameter of 100mm making it ideal for connections to soil or mechanical extraction pipes up to 100mm or if there is no pre-existing pipework to connect to, Manthorpe also offer the GRPA Flexi Pipe 455mm which connects directly onto the GTV-AD adaptor.

  • Suitable for use with Manthorpe GTV in-line tile vents
  • Supports piping up to 100mm in diameter
  • Used to convert vents into service terminals
  • Ideal for mechanical extraction fans or soil pipe ventilation
  • Can be retrofitted
