When you're setting up commercial kitchen drainage, the grease trap is the unseen workhorse. In the world of warewashing sanitation grease, choosing the right interceptor means deciding between two very different approaches: a compact stainless steel set at $49.02 and a 50L plastic separator at $70.15. Both keep oil and grease out of your wastewater line, but they are built for different kitchens and different workloads. The right choice comes down to how much wastewater you produce at peak times and how much space you can spare under the sink.
Quick Verdict
If you have a smaller kitchen, modest fryer use, and limited cabinet space, the stainless steel interceptor set is the easier choice. It is less expensive, takes up less room, and uses a durable metal body. If you run a busier restaurant, cafeteria, or fast food kitchen with higher wastewater volume, the 50L model is the stronger pick. Its larger reservoir means you won't need to empty the trap as often.

Where Each Product Wins
- Stainless Steel Grease Trap Interceptor Set: This is the pick for a compact space and a tighter budget. It also brings metal construction to a small footprint.

Product Notes
Stainless Steel Grease Trap Interceptor Set For Restaurant Kitchen Commercial
This set is built around a metal body with a wastewater inlet and outlet diameter of 4.8cm, which matches standard plumbing connections. The package includes a drainage pipe, a lid, and the accessories needed for installation, so you won't need to source extra parts. It's designed for treating mineral oil, animal oil, vegetable oil, and mixed oil-water waste, which covers most commercial kitchen output. The compact body helps it fit into tighter cabinets. The trade-off is that the holding space fills faster in a high-volume kitchen, so this unit is best suited to lighter grease loads and smaller prep areas.
50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink
This separator is aimed at restaurants, fast food chains, bars, cafes, and public cafeterias. It uses a top water inlet and left-side water outlet, and it's designed for freestanding or under-counter placement. Assembly is required, and the package includes a drainage pipe, a pair of gloves, and a seal. The plastic body with rubber components keeps the unit relatively light, which helps during positioning. The trade-off is that plastic won't feel as solid as stainless steel, and the larger size means you need to plan the space before installation. This is the unit to reach for when you expect continuous oil-heavy wastewater and want a larger reservoir between empties.
Final Choice by Use Case
For a single-sink setup with light frying and limited cabinet space, the stainless steel interceptor set is the practical way to go. For a multi-sink kitchen with heavy frying or frequent dish service, the 50L grease trap's extra capacity and flow rate justify the higher price. Choose based on your peak wastewater volume, and the right unit will keep your drain line clear.
