Installing a grease separator in the ground offers many additional advantages: No useful space in the basement is lost, instead the entire system disappears under an odour-tight cover outside the building. The separator remains easily accessible for maitnenance and inspection via integrated steps. The complete root-proof chambers of our EasyClean ground grease separator made of polyethylene are particularly easy to place in the excavations and can be adapted individually to the ground level with the help of vertically adjustable upper sections.
