Kitchen grease and wastewater need a place to go before they reach the drain line. The harder part is deciding which kind of hardware should sit between the sink and the sewer: a full under-sink interceptor, a compact stainless steel trap, a collector for a roof-vent system, or a make-specific replacement assembly. This guide compares four warewashing sanitation grease options by their listed prices and feature sets so you can match the product to your actual kitchen layout.
Quick take
All four are new products, but they solve different problems. The Accurex Assembly, Grease Trap Without Absorber 475538 is the highest-priced option at USD 79.99 and a part-numbered OEM replacement. The Dayton 48C174 Grease Trap Collector Box at USD 62.00 is made for upblast roof ventilators. The 50L Grease Trap Interceptor Oil-water Separator at USD 70.15 is the dedicated under-sink interceptor. The grease trap interceptor at USD 49.02 offers the lowest listed price.
Prices run from USD 49.02 to USD 79.99, a $30.97 spread between the compact option and the OEM assembly.

Accurex Assembly, Grease Trap Without Absorber 475538

When the goal is to replace a specific grease trap assembly rather than outfit a new sink, this Accurex unit gives you a straightforward match: it carries model number 475538, the MPN 475538, and it comes from the United States. It is described for use in medical, lab, and dental settings, so buyers managing grease collection in those professional environments have a reason to keep it at the top of the list. The main limitation is in the title: it is a grease trap without absorber. That means you are getting the assembly itself, not a full separation system that includes absorbent material. If your existing setup already includes the absorber, this part matches that replacement scenario. If not, plan the rest of the assembly separately.
Dayton 48C174 Grease Trap Collector Box for Upblast Roof Ventilators

Restaurant exhaust systems that push air through roof ventilators need a place for grease to collect, and that is exactly the slot this Dayton product fills. The 48C174 is labeled as a grease trap collector box for upblast roof ventilators, so it suits a kitchen where the hood, duct, and roof ventilator are already in place. The practical upside is specialization: instead of buying a general-purpose under-sink interceptor, you are adding a grease collector at the ventilation point. The flip side is that a collector box is not an oil-water separator. It captures grease, but it should not be expected to handle the oily wastewater draining out of a sink. Buyers who need that kind of liquid separation will need a product like the 50L interceptor covered below. For roof-level grease management, this Dayton box is the only option in the group aimed at that job.
50L Grease Trap Interceptor Oil-water Separator Restaurant Kitchen Under Sink

Of the four options, this is the one that looks like a full under-sink oil-water separation project. The title calls it a grease trap interceptor and oil-water separator, and the attribute list backs that up with a 50L/13.21gal capacity and a flow rate of 2.1T/4629.71lbs/h. The package includes the separator, drainage pipe, gloves, and sealing ring, with assembly required. That makes it a reasonable candidate for a restaurant, cafeteria, or food prep area where you want a dedicated under-sink unit rather than a part. The trade-off is that the body material is plastic and the package lists a 45×35×30cm product size, so it will need counter or cabinet space under the sink. It also depends on your willingness to handle assembly before the unit goes into service.
Grease Trap Interceptor Stainless Steel For Restaurant Kitchen Wastewater Oil Us

This stainless steel interceptor is the compact model in the group. It is built for restaurant kitchen wastewater oil work, with a stainless steel body, four stages of filtration, and an automatic shut-off device described as helpful for open-air placement because it shuts down when it rains. The wastewater inlet diameter is 4.8cm/1.9 inches and the grease outlet is 2.2cm/0.86 inches, which gives concrete sizing clues for connecting plumbing. Its 35×25×23cm footprint means it may be easier to slip into tight spaces than the larger 50L model, but it also means you should not assume it will hold the same volume as the bigger plastic unit. If stainless construction and point-of-use flexibility matter more than maximum capacity, this is the one to weigh.
