50L Grease Trap Interceptor: Is Its Under-Sink Format Right for Your Kitchen?

The 50L Grease Trap Interceptor is a listed under-sink oil-water separator for foodservice settings that need a defined 50L capacity, compact rectangular dimensions, and a left-side outlet.

Last updated Aug 17, 2026

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.

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.
