Rat protection and Back-flow fuses

All rat protection and back-flow fuses are produced in stainless steal.

All rat protections are VA approved and the back-flow fuses are CE approved.

The rat protections are manufactured at HF. Hansen, who has more than 20 years of experience.

A rat protection works as follows: The rat protection is mounted in a chamber outside the house, and functions with help from the double flap-system. When the rat “lifts” the front flap, the back will lock, and, hereby, the rat cannot pass.

A back-flow fuse works as follows:

The back-flow fuse is placed horizontal on the outfall from the house and into a chamber, and at unexpected water rise in the chamber, the floater will flow upwards, and the flap will close.
