RoFETT — underground grease separator for high capacity.
EN 1825-2 certified. From 7 to 25 L/s. For restaurants, hotels and industry.
The RoFETT is a horizontal grease separator made of high-density polyethylene for underground installation. EN 1825-2 certified, with a grease chamber and settling chamber integrated into the same single-piece tank. Available from 7 to 25 L/s — higher capacity models on request. Factory pre-assembled, with all connection openings pre-formed.
Why the RoFETT?
In premises that produce grease — restaurants, industrial kitchens, hotels, canteens and the food industry — the law requires a grease separator to be fitted before the connection to the public sewer. The RoFETT complies with EN 1825-2 and is easy to install underground, without taking up space inside the premises.
The single-piece, weld-free HDPE tank withstands soil pressure and groundwater. The integrated settling chamber — within the same shell — removes the need for a separate pit, simplifying installation and cutting costs. Single access through a DN600 cover, compatible with telescopic extensions for installation at different depths.
