我们的优势
每一个细节都经过深思熟虑
100% water yield
100% water yield
The complete package includes a basket filter for 100% water yield, making it ideal for small roof areas or downstream infiltration.
Telescopic/Tiltable
Telescopic/Tiltable
The GRAF telescopic dome shafts are continuously height-adjustable and can be tilted by 5 degrees. This makes it easy to adapt to the upper edge of the terrain.
Sealed to the top edge of the ground
Sealed to the top edge of the ground
The ingress of seepage water can impair the water quality. GRAF tank and filter solutions are therefore sealed up to the top edge of the ground.
