This separator for greasy waste water is suitable for freestanding installation in frost-protected rooms below a sink. Free of any metal components, the collecting tank is made of durable plastic (PP) equipped with an integrated sludge trap. An odor-tight lid with a wrap-around seal and closure clip allows easy access during manual emptying and cleaning. The separator also has quick-release pipe connections for easy removal, and an inspection window for on-site installation is available as an option for visually checking the thickness of the grease layer.
