Hunter Air Admittance

The importance of allowing air to enter any soil or waste system should never be overlooked during design and/or installation. The result of poor ventilation is most commonly the siphonic removal of water seals from traps, causing the unpleasant gurgling noise and allowing foul odours to enter living space.
Hunter offer a full range of solutions to ensure adequate ventilation for the drainage system including the S450 Air Admittance Valve, for soil stack applications, the W150/151 Gurgle Master and innovative GurgleMaster II for domestic and commercial waste installations.
A range of products is also available in European sizes. For
more information please contact our export department.
