ILA Internal cascade for DN 1000 manholes for the connection of sewage systems of different heights, downpipe DN 250/200, gray ILA1000250_0000

The internal ILA cascade is used to connect sewage elements of different heights. The following nominal diameters are available: DN/OD 160, DN/OD 200, DN/OD 250. The cascade provides optimal protection against corrosion and is suitable for installation in existing DN 1000 or new concrete wells. The opening enables trouble-free inspection and cleaning. Since the installation of the cascade does not require much space, you can still move freely in the sewer well. Unlike external cascade wells, only a small trench is required, which saves time and money. Indoor installation is safer and easier. The set includes: • internal cascade with pre-drilled holes for mounting on the chamber wall, the set includes 3 stainless steel screws / wall plugs • stainless steel clamp for fixing the downpipe •
