Quick Take
If you are outfitting a commercial kitchen, the first decision is whether you need a full dish machine or just a way to keep grease out of the drain. The four options here span a listed-price range from about $49 to about $2,900, and they include one full dish machine, one large oil-water separator, and two under-sink grease traps. The right pick depends on your space, your wastewater volume, and whether you need a complete dishwashing solution.

How to Choose
Start with the job you need to do. If the goal is to separate oil and water before wastewater leaves the sink, a grease trap or interceptor is the relevant piece of equipment. The 50L plastic model gives you the largest tank capacity in this set, while the two under-sink grease traps are more compact. If the goal is to wash dishes rather than only trap grease, the ADS dish machine is the only full dishwashing unit here, and it is described as a corner-style unit.
Condition also plays a role. Two of the four products are listed as new, and two are listed as used. Because the new under-sink grease trap is the lower-priced version of the used under-sink grease trap, the condition difference is worth weighing side by side.

Product Notes
ADS L903DWCS Commercial Restaurant Dish Machine
This is the only full dish machine in the group, and its corner-style design gives it a specific place in a commercial kitchen. It is Energy Star qualified and comes with chemical pumps included, which means the dishwashing sanitation setup can rely on these integrated components. The unit is 72 inches high and 34 inches wide, and it is described as made in the United States. The listed price is $2,899.95, the highest among these four products. It is also listed as used rather than new, so that condition is a key factor to weigh if you are comparing it against new grease traps.
50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink
If your kitchen produces a large volume of oily wastewater, this plastic interceptor offers a 50L/13.21gal capacity, which is bigger than the 18-20L stainless steel traps in this comparison. It is listed as new and priced at $70.15, and the package includes a drainage pipe, a pair of gloves, and a sealing ring. The material is plastic, and the unit is designed to be freestanding or placed under a countertop. The 50L capacity is the main reason to consider it, but the plastic construction may not be what you want if you were expecting stainless steel.
Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US (New)
This stainless steel under-sink grease trap is listed as new and has the lowest listed price in this comparison at $49.02. It has an 18-20L capacity, a 4.8cm wastewater inlet, and a 4.8cm water outlet, and it comes with a drainage pipe and lid. The compact 35*25*23cm size makes it a fit for smaller kitchens or tight under-sink spaces. The limitation is simply the smaller capacity compared with the 50L plastic separator, so if you need to hold more grease between cleanouts, the larger tank is the more suitable option.
Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US (Used)
This version of the stainless steel under-sink grease trap shares the same 18-20L capacity, 4.8cm inlet and outlet openings, and 35*25*23cm dimensions as the new stainless interceptor. Its listed features include a compact design, unique appearance, and high reliability. The key difference is that this unit is listed as used, and the listed price is $129.99. That makes it the higher-priced stainless option, while the new version of the same design is listed at $49.02. If you want a stainless under-sink grease trap and are comfortable with a used unit, this covers the same capacity, but the new version is the lower-priced choice.
Final Recommendation by Use Case
For a full commercial dishwashing solution, the ADS L903DWCS is the only product here that functions as a dish machine. Its listed price is the highest in the set, and it is listed as used, so those two factors should be part of the decision.
For grease-heavy kitchens, the 50L plastic interceptor offers the largest tank capacity among these four products.
For a new under-sink grease trap that is compact and lower-priced, the new interceptor is the version to compare against the used unit.
If you specifically want a used version of the same under-sink grease trap, the used interceptor covers the same capacity, but the new version of the same design is the lower-priced listing.
