Funke ILA Internal Backdrop

For bridging height differences in the sewer system

The Funke ILA Internal Backdrop has been developed to bridge height differences in the sewer system. The standard version of the unit is available in the nominal diameters DN/OD 160, DN/OD 200 and DN/OD 250, and is available to fit DN 1000, 1200 and 1500 concrete chambers. The unit has an EPDM seal on the back to ensure a tight seal to the chamber wall.

The Funke ILA Internal Backdrop can be used for new chambers or be retrofitted in existing ones. The pipe is connected with a pipe section passed through the chamber wall. The wall transition can be made either with a pre-produced chamber lining or with an on-site ring space seal. An opening allows for easy inspection and access.

Thanks to the small space demands of the Funke ILA Internal Backdrop, the chamber remains accessible. However, the accessibility has to be checked on a case-by-case basis for inlets with a nominal diameter of 250mm or higher.

The advantages in practice:

• minimal space requirements
• quick and easy installation, minimal soil excavation
• easy inspection and cleaning
• can also be installed in existing systems (chamber structures)
