Anti Extrusion 320mm Stainless Steel Siphonic Roof Drain
The siphon rainwater bucket is made of: the siphon rainwater bucket chassis is stamped from high-quality 304 stainless steel. The pressure ring and shroud are made of hard aluminum alloy and zinc alloy die-casting.
It has the characteristics of anti-corrosion and anti-extrusion. The siphon rainwater bucket has a strong anti-vortex function,
which can well prevent air from being brought into the entire system through the water flow at the entrance of the rainwater bucket, and when the water level in front of the bucket rises to a certain degree, a water seal is formed to completely block the air from entering. And make the rainwater steadily flood the drain into the drain pipe. The siphon rainwater bucket minimizes the depth of water accumulation in the gutter, minimizes the rain load on the roof, and increases the rated flow of the rainwater bucket.
