Extension for EcoLeader R-3400 - R-7100 rainwater and septic tanks The purpose of the EcoLeader DN640 extension is to enable the tank to be founded deeper in the excavation. The tank manhole extension is made of high-quality polyethylene, which is resistant to adverse working conditions. It does not corrode when exposed to UV and moisture. It is a guarantee of many years of failure-free operation.
The height of the superstructure can be adapted to the design requirements. A DN690 cover is compatible with the superstructure.
The superstructure is suitable for
Tanks R-3400 - R-7100
Z-1000 and 2000 tanks (the superstructure has a slightly larger diameter than the flange - it overlaps completely, needs to be fixed with screws and insulated with silicone).
