Quick verdict
If you run a commercial kitchen or food prep space, grease in the drain is a constant battle. This 18-20L stainless steel under-sink grease interceptor tackles that with four-stage filtration and an automatic shut-off when it rains. At USD 49.03, it offers a direct way to separate oils from water before they move further into the plumbing. The unit is built for treating mineral oil, animal oil, vegetable oil, mixed oil, and emulsified oil-water combinations.
Who it suits
This trap suits commercial foodservice settings where wash water carries a mix of cooking fats and oils. Its compact 35 x 25 x 23 cm size makes sense for an under-sink location, and the stainless steel body is meant to stand up to frequent use in wet conditions. The automatic shut-off also makes it a candidate for open-air placement, since it is designed to close when rain hits.
What stands out
Four-stage filtration is the central feature, allowing the unit to separate oil and water through multiple stages rather than a single screen. The high-quality stainless steel construction supports long-term service. Another highlight is the automatic shut-off device: if the unit is set up in an open-air space, it shuts down automatically when it rains. With an 18-20L capacity and dimensions of 35 x 25 x 23 cm, the interceptor keeps a relatively small footprint.
Meaningful trade-offs
The main thing to weigh is capacity. The listed option is an 18-20L unit, which is realistic for many prep sinks but may feel small for larger-volume drains. The design is fixed around that capacity range, so match it to your sink's grease load before installing. Because the unit is meant for under-sink use, you'll want to plan the connection to your existing plumbing and ensure the trap fits in the space available.
Bottom line
For an under-sink grease trap priced at USD 49.03, this stainless steel interceptor combines four-stage filtration, automatic rain shut-off, and an 18-20L capacity. It is a solid fit for commercial kitchens that need a compact, durable way to keep grease and oil out of the drain. If your volume stays within that capacity, it should serve you well.

The reason to choose this unit is the pairing of four-stage filtration and rain-activated shut-off in a compact stainless steel design. The limitation is the fixed 18-20L capacity: if your sink produces heavy grease volume, you'll need a larger interceptor to handle the load.
