Choosing the right interceptor for a commercial kitchen isn't just about catching grease - it's about matching the unit to the amount of wash water you send down the drain. If you're comparing options for your warewashing sanitation grease setup, the two units here sit at opposite ends of the price and specification spectrum: a compact stainless steel grease trap interceptor set and a steel interceptor built around a performance rating. The right pick depends on whether you need a convenient kit or a clearly rated unit that can handle busier kitchen output.
Quick Verdict
If you want a stainless steel interceptor that comes as a set, the Stainless Steel Grease Trap Interceptor Set is the more convenient choice. If your kitchen needs a rated interceptor, the 8lb Commercial Steel Grease Trap Interceptor is the stronger pick.

Where the Stainless Steel Grease Trap Interceptor Set Wins
The stainless set wins on package contents. It is the option that includes a drainage pipe and lid, so the main installation pieces are together. It is built from stainless steel, which is a plus if you prefer that material for your warewashing sanitation grease setup. The compact dimensions also make it easier to fit into tighter kitchen spaces.
Where the 8lb Commercial Steel Grease Trap Interceptor Wins
The steel unit wins when you need a spec you can plan around. Its title includes PDI approval, which makes it a stronger pick for kitchens that want a rated unit. The steel construction is aimed at foodservice use.
Product Notes
Stainless Steel Grease Trap Interceptor Set For Restaurant Kitchen Commercial

This kit is the straightforward way into a grease trap if you want everything in one order. It comes with a drainage pipe and a lid alongside the interceptor, and at $49.02 it is the less expensive option. The stainless steel body is paired with an 18-20L capacity, while the water inlet and outlet are both 4.8 cm. For compact installs, that is a useful package. The limitation is that the set's specification focuses on capacity and dimensions rather than a unit rating.
8lb Commercial Steel Grease Trap Interceptor - 4 GPM, PDI Approved

This unit is anchored by performance specs: an 8lb capacity, a 4 GPM flow rate, and PDI approval in the name. If your kitchen's grease interceptor needs to handle a busier flow, those specs make a strong case. The steel construction is meant for commercial use. The trade-off is the higher list price. If you do not need that flow rating, the compact stainless set gives you a workable kit for less.
Final Choice by Use Case
Choose the Stainless Steel Grease Trap Interceptor Set when you want a stainless build and an all-in-one kit with the main installation pieces. Choose the 8lb Commercial Steel Grease Trap Interceptor when your priority is a performance-rated steel unit. These two interceptors serve different demands, so match the choice to the volume of wash water you actually move in your warewashing sanitation grease setup.
