When you are setting up warewashing sanitation grease control, the first decision is not which detergent to use-it is how you keep fats and oils out of the wastewater. A grease trap has to fit under the sink, handle the volume your kitchen actually sends down the drain, and do it without becoming a maintenance headache. The Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US is aimed squarely at that under-sink problem.
Quick verdict
The Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US is a compact stainless steel unit for under-sink oil-water separation. At USD 49.03, it offers a straightforward way to capture grease before it reaches your drain lines. The 18-20L capacity and 35 x 25 x 23 cm footprint tell you this is a smaller interceptor, not a large floor tank.
Who it suits
If your kitchen runs a standard prep sink or a single warewashing station where oils, fats, and food residue get rinsed off cookware, this size can be a sensible fit. The unit is designed to handle mineral oil, animal oil, vegetable oil, mixed oils, and various emulsified oil-water mixtures, which covers a broad range of everyday commercial cooking byproducts.
What stands out
Stainless steel construction gives the trap durable, corrosion-resistant potential in a wet environment. The included components-grease trap, drainage pipe, lid, and installation accessories-mean the basic parts are there when you start.
The 4.8cm wastewater inlet and outlet plus a 2.2cm grease outlet are compact but workable for a small under-sink installation. The separate grease outlet is what lets fats rise and be diverted instead of continuing downstream.

The reason to choose this grease interceptor is its compact stainless steel build and complete accessory set at a $49.03 price. The limitation to keep in mind is the 18-20L capacity: it suits modest grease loads, so busier kitchens with multiple sinks may need more capacity.
Meaningful trade-offs
The compact capacity is the main trade-off. At 18-20L, this unit is best for light-to-moderate foodservice use where the sink is not processing extremely high volumes of oily water. If your operation runs multiple prep sinks or heavy frying, a larger interceptor is worth planning for. The 4.8cm inlet and outlet sizing is a fixed detail, so it will suit installations built around that size.
Bottom line
If your needs fit an under-sink interceptor with 18-20L capacity and compact dimensions, this product is a solid candidate at USD 49.03. It pairs stainless steel durability with a complete accessory package and a clear oil-water separation layout for a modestly sized commercial sink.
