Managing warewashing sanitation grease means balancing separator capacity with the physical realities beneath or beside the counter. The key question is not simply whether a grease interceptor is needed, but whether its size, pipe orientation, and placement format fit the kitchen arrangement being planned.
Quick verdict
At USD 70.15, the 50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink is a straightforward choice for a foodservice setup seeking a listed 50L oil-water separator in a rectangular, under-countertop-oriented format. Its stated applications span kitchens, restaurants, fast-food chains, bars, cafés, public cafeterias, food factories, and schools.
The strongest reason to select it is the combination of a defined 50L/13.21-gallon capacity and a relatively contained 45 × 35 × 30 cm footprint. The principal constraint is equally clear: assembly is required, and the outlet is positioned on the left.
Who it suits
This interceptor makes the most sense for a kitchen plan that can allocate space for its stated 45 × 35 × 30 cm dimensions and use its listed freestanding or under-countertop mounting format. A buyer focused on a specified 50L vessel, rather than an unspecified separator size, has a clear capacity reference for planning.
It is also relevant where a top water inlet works with the intended plumbing arrangement. The inlet diameter is listed as 4.5 cm, while the left-side outlet diameter is 3 cm. Those fixed connection details are central to whether the unit aligns with the layout.
What stands out from the listed details
The rectangular grey separator uses a top inlet and left outlet, creating a clearly defined flow orientation. Its listed flow rate is 2.1T/4,629.71 lbs per hour, and it includes a 78 cm drainage pipe. A seal and one pair of gloves are also included.
For placement planning, the unit's net weight is listed as 3.8 kg, with a gross package weight of 4.6 kg. The stated 3-4 mm thickness is another concrete construction detail for shoppers comparing similarly sized interceptor formats.
Meaningful trade-offs
A 50L capacity can be a useful target when that is the intended vessel size, but the unit is not dimension-free: its 45 cm length, 35 cm width, and 30 cm height need a dedicated location. The left outlet is not a flexible, all-direction detail; it establishes a particular orientation for the separator.
Assembly required is another practical consideration. The included drainage pipe, seal, and gloves give the package a defined component list, yet the installation arrangement still needs to accommodate the top inlet and left outlet configuration.
50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink

Choose this interceptor when a 50L under-countertop or freestanding oil-water separator at USD 70.15 fits the planned kitchen footprint and a left-side outlet matches the intended orientation. Its concrete appeal is the specified capacity alongside a 78 cm drainage pipe and top-inlet design. The trade-off is its fixed 45 × 35 × 30 cm body and left outlet, plus the requirement for assembly.
Bottom line
The 50L Grease Trap Interceptor is best approached as a clearly sized, direction-specific separator for commercial kitchen settings. Its 50L capacity, stated dimensions, top inlet, and left outlet give a shopper concrete planning points rather than a vague all-purpose format.
