Quick take
Commercial kitchens produce greasy wastewater that can clog drains and create sanitation problems. Grease trap interceptors separate oil and water before the water moves down the line. The four options covered here span USD 49.02 to USD 535.00, so the choice usually comes down to flow volume, material, and space constraints. The compact stainless steel unit is the lowest-priced option, the two 50L plastic separators share the same mid-range price and specs, and the 30 LB carbon steel interceptor is at the top of the price range.

Product notes
Grease Trap Interceptor Stainless Steel For Restaurant Kitchen Wastewater Oil Us
The stainless steel body and four stages of filtration make this a practical compact interceptor. It also includes an automatic shut-off device for open-air placement, and the overall dimensions are 35 x 25 x 23 cm, so it fits well in tight spaces. The grease outlet diameter is listed at 2.2 cm (0.86 in) and the wastewater inlet at 4.8 cm (1.9 in). If you need a small unit that won't take up much room, this is the one to start with. For higher-volume drainage, you would need to move to one of the larger-capacity options.
50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink
Both 50L grease trap entries share the same specifications, so they are interchangeable for an installation. The PP plastic body keeps the unit lighter than steel, and the 50L/13.21gal capacity provides more working volume than the compact stainless steel interceptor. The listed flow rate is 2.1 tonnes per hour, and the product dimensions are 45 x 35 x 30 cm, with a top inlet and left outlet. It suits kitchens, restaurants, cafes, and food production areas that want under-sink or freestanding separation without moving to a steel unit. The trade-off is that the plastic shell is not as sturdy as carbon steel.
50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink
This second 50L entry is identical in material, capacity, and flow rate to the previous one, so the two are interchangeable for any installation. The PP plastic construction gives you the same 50L/13.21gal capacity and the same 2.1 tonnes-per-hour flow rate. The listed package includes an oil-water separator, drainage pipe, gloves, and sealing ring. If you need a larger under-sink unit but want to stay in the middle of the price spread, either 50L separator works. The main caveat is material: plastic does not have the same strength as the carbon steel interceptor at the top of the range.
Carbon Steel Grease Trap Interceptor for Restaurant Under Sink Kitchen | NSF
This is the only unit in the group with carbon steel construction and an NSF designation in the title. The 30 LB size carries a listed flow rate of 15 gallons per minute. Features include no-hub connections, a T-vent, non-skid deck plate, removable baffles, and an 11-gauge carbon steel body with corrosion-resistant coating. PDI Certified is also listed. If you have a busy kitchen line and need a higher-flow interceptor, this is the one to choose. The extra capability comes at the top of the price range.
Final recommendation by use case
- Tight space / lower-volume kitchen: Choose the Grease Trap Interceptor Stainless Steel for a compact stainless steel unit with four-stage filtration.
- Mid-volume kitchen: Pick one of the 50L Grease Trap Interceptors when you need 50L of capacity and a 2.1T/h flow rate.
- Higher-volume kitchen: Go with the Carbon Steel Grease Trap Interceptor when you want a 30 LB steel unit, a 15 GPM flow rate, and the feature set described above.
