RoMast — above-ground grease separator. No excavation.
Installation under a worktop or in a floor box. From 0,25 to 4 L/s.
The RoMast is an HDPE/PVC grease separator for above-ground installation, EN 1825-2 certified. Where burying is not an option — basement kitchens, premises with concrete slabs, refurbishments — the RoMast installs under a worktop or inside a floor box, with no excavation. Available from 0,25 to 4 L/s.
Why the RoMast?
In kitchen refurbishments, basement installations or spaces where excavation is not feasible, the RoMast is the legal and practical solution. EN 1825-2 does not require underground installation — only separation efficiency — and the RoMast meets every efficiency requirement in a compact housing that fits under the sink.
HDPE/PVC construction ensures chemical resistance to animal and vegetable fats, detergents and kitchen effluent. The easy-open inspection cover allows routine cleaning without tools. The larger models (NG2 and NG4) can be installed in service floor boxes or in outdoor service areas.
