BLANKE AQUA WM (drain collar)
The BLANKE AQUA WM (drain collar) is a special design of a punched sleeve, similar to BLANKE AQUA SHIELD BM/WM (floor/wall pipe sleeves), but with a deepdrawn collar. This collar ensures an effective and safe connection of the waterproofing system (for example BLANKE AQUA SHIELD 100) with drainage tubes. The drain collar can either be used as an interior collar (BLANKE AQUA WM DN 50-IA) or an exterior collar (BLANKE AQUA WM DN 50 AA) for drains. The collar dimensions are adapted to the following standard sizes: DN 50/DN 70/DN 100).
