Stack Diverter

Introducing Plastec’s Stack Diverter. A new Reduced Velocity Aerator Stack System (RVASS), invented by Plastec Australia Pty Ltd, that is unmatched in the market place with its unique design and ability. The only Australian made RVASS, our Stack Diverter is designed to balance the positive and negative pressure in drainage stack systems which eliminates siphonage of trap seals, without the need for a relief vent. This is the ideal system for high rise buildings, hotels and multi-storey residential buildings, being most effective in buildings higher than three storeys.
