Grease is a real problem in commercial kitchens. When oils and food particles hit the drain, they cool, congeal, and cling to pipe walls, eventually blocking the flow and creating costly backups. A grease trap interceptor sits between your sink and the sewer line, separating oil and water so the waste stream stays clean. In the warewashing sanitation grease category, two stainless steel interceptors are facing off at the same $49.02 price, but they take different approaches to handling that greasy wastewater. One leans toward installation convenience; the other toward outdoor durability. Here's how to decide which one belongs in your kitchen.
Quick Verdict
Choose the Stainless Steel Grease Trap Interceptor Set if you want a bundled pipe and lid for simpler installation. Choose the Grease Trap Interceptor if you value rain protection and multi-stage oil separation.
At a Glance: Shared Foundation
The table below shows the specifications that are identical across both units, so the real choosing happens on the feature differences.
| Feature | Stainless Steel Grease Trap Interceptor Set | Grease Trap Interceptor |
|---|---|---|
| Price | $49.02 | $49.02 |
| Material | Stainless Steel | Stainless Steel |
| Overall Dimensions | 35×25×23 cm | 35×25×23 cm |
| Wastewater Inlet Diameter | 4.8 cm / 1.9" | 4.8 cm / 1.9" |
| Grease Outlet Diameter | 2.2 cm / 0.86" | 2.2 cm / 0.86" |
Where Each Product Wins
The Set wins on installation readiness because it comes with a drainage pipe and lid, so you have the essential accessories without a separate trip to the supply store. It also states a clear 18-20L capacity, which makes sizing straightforward for a typical restaurant sink. The Interceptor wins on weather resilience: its automatic shut-off protects the unit when rain hits, and its four-stage filtration gives it extra chances to separate oil and solids. If your installation is exposed to the elements or you want a more thorough separation process, this is the one.
Product Notes
Stainless Steel Grease Trap Interceptor Set
This unit is the kit approach to grease management. The package includes the interceptor, a drainage pipe, and a lid, so you're not hunting for separate components when you're ready to install. It's also the only one of the pair that lists a capacity range: 18-20L, giving you a concrete benchmark for a medium-volume kitchen sink. The smooth thread design and secure connections are built for daily service, and it handles mineral, animal, vegetable, and mixed oils, which covers most commercial cooking fats. The trade-off is that the capacity is a fixed range, so a high-volume frying station may require more frequent manual emptying to keep the unit working at its best.
Grease Trap Interceptor
This interceptor is built for environments where the weather is a factor. An automatic shut-off device closes the unit when it rains, so open-air and uncovered setups are protected from downpours that could flood the separator. Inside, four stages of filtration mean more opportunities to pull grease and solids out of the wastewater before it moves on. The body and same 35×25×23 cm footprint as the set version fit the same under-sink or behind-dish-line spaces. For outdoor installations, that automatic shut-off is a genuine peace-of-mind feature, especially during stormy months. The limitation is that the rain shut-off is a feature you'll rarely use if the trap is installed indoors; the four-stage filtration remains the active benefit, but the weather protection becomes a dormant safeguard.
Final Choice by Use Case
If your grease trap will live indoors under a sink or behind a dish station, and you want a complete kit, choose the Stainless Steel Grease Trap Interceptor Set. If the trap will sit outdoors or in an open-air building, choose the Grease Trap Interceptor for its weather-ready design. The core plumbing specs are the same, so the decision comes down to installation location and whether you prefer a bundled package or specialized weather protection.
