John Boos GT-20 Grease Interceptor: Reliable Grease Control for Commercial Kitchens

A clean, efficient kitchen depends on proper wastewater management, especially in busy foodservice environments where fats, oils, and grease are produced daily. The John Boos GT-20 model is designed to help commercial kitchens reduce grease buildup before it reaches the plumbing system. When connected to a dishwasher or sink, this grease interceptor separates grease from water using a removable baffle system that improves flow control and makes maintenance more manageable.

The process is simple but effective. As wastewater enters the unit, the internal baffle slows the flow and allows separation to occur. Because grease is less dense than water, it naturally rises to the top of the interceptor. Cleaner water then continues through the outlet and moves into the sewer system. This helps reduce the risk of clogged drains, unpleasant odors, plumbing backups, and costly service calls.

With a 20-gallon holding capacity and a 10-gallon-per-minute flow rate, this unit is well suited for commercial settings that need dependable grease separation without taking up excessive space. Its carbon steel body provides strength for repeated use, while TIG-welded construction adds durability and long-term performance. These features make it a practical choice for restaurants, cafés, bakeries, food prep areas, and other professional kitchens that need consistent wastewater control.

Routine cleaning is also easier thanks to the removable baffle. Staff can access the internal components more conveniently, helping maintain sanitary conditions and reliable operation. Proper maintenance also supports local wastewater compliance, which is an important concern for many foodservice businesses.

Grease traps for restaurants are essential because they protect plumbing infrastructure and help kitchens operate smoothly during peak service hours. While some larger facilities may compare different models such as the John boos gt 100 grease interceptor, the GT-20 remains a strong option for kitchens that need a compact, durable, and efficient grease management solution.

For businesses looking to protect their drains, reduce maintenance issues, and improve kitchen efficiency, this interceptor offers a dependable balance of capacity, construction quality, and ease of use.
