Telescopic extension DN600 H460, for relieving ring and manhole, with gasket, for ONE2CLEAN biological treatment plants and CARAT septic tanks, black color 371021

Telescopic extension for septic tanks and treatment plants

This telescopic extension, designed for one2clean biological treatment plants and CARAT septic tanks, provides a practical solution for installers and end-users. It enables aesthetic and functional finishing of the installation, providing easy access to the inside of the tank through a dedicated manhole (available separately). The design allows for adjustment to uneven terrain thanks to the adjustable height and inclination angle of up to 5%, which facilitates installation and integration with the surroundings.

Construction and application

The extension has been designed to work with a relieving ring and a manhole, which are not included and must be purchased separately. It is made of durable plastic, resistant to weather conditions and loads. Its main task is to secure access to the inside of the tank, and to enable safe use by pedestrians or, in the case of using an appropriate manhole (cast iron), also by vehicles weighing up to 3.5 tonnes. This solution is ideal for both private properties and public places.
