Spa Skimmer Vent Kit - AS1926.3 Compliant. 304 Stainless steel/graphite vent fitting.

Australian Standard AS1926.3 requires all skimmers be fitted with atmospheric ventilation with minimal cross sectional surface area of 315mm square which is equivalent to a minimum internal diameter of 20.02mm. There are no common spa fittings that enable this minimal dimension without the need to fit multiple parallel components.

This minimum cross sectional area must be maintained throughout the kit. where barbed fittings are used, often 2 x barbed systems in parallel still do not meet the minimum requirements.

This kit provides a minimum ventilation surface area of approx 365mm square, using just the one assembly.

The purpose of the vent is to cause air to be drawn into the pump causing cavitation in the event a persons body becomes trapped against the skimer opening to the spa. The cavitation of the pump will break the suction seal of the body allowing a trapped person to become freed.

• 304 SS vent fittings - 59mm diameter, requires 45mm diameter hole in the top of the spa and in the skimmer box/enclosure, 1"/25mm socket - straight body 
• 1m of spa flex supplied in the kit that can be cut short or extended as required. (images show a short section, but 1m is included)
• 2 x elbow fittings included that don't necessarily need to be utilised depending on the installation.
