With a solid reputation for quality and value, the equipment and supplies manufactured by Prima Supply are sure to be a smart choice.

Grease traps - a.k.a. grease trap interceptors - are one piece of commercial restaurant equipment that's easy to overlook. There are more exciting and aesthetically pleasing pieces of equipment out there, to be sure. But few other pieces of equipment provide such an important service to restaurants and commercial kitchens as the grease trap. Basically, the trap acts as a collection point for excess fats, oils, and greases from kitchen sewage before it reaches the main sewage line. As a result, this simple piece of equipment prevents the main sewage treatment plant in your local area from being clogged with an excessive amount of fats, oils, and greases, thus adverting a potential disaster. Atlantic Metalworks's GI-40 is designed with this purpose in mind and comes constructed with durable carbon steel. The GI-40 has an overall capacity of 40 lbs and can take in approximately 20 gallons of waste per minute, making the 40lb grease trap perfect for medium-sized restaurants and commercial kitchens. Furthermore, the GI-40 is PDI (Plumbing and Drainage Institute) certified and comes with a one year warranty against defects in material and/or workmanship from the time of purchase. Overall, Atlantic Metalworks’s 40 lb grease trap interceptor offers restaurant owners a dependable and affordable solution for their grease collecting needs.

well built - right price

Atlantic Metalworks GI-40 - 40 lb 20 gpm Grease Trap Interceptor, this unit is well built, comes with the correct parts and is easy to remove the lid. Would like to see a better gasket type used, the foam based gasket tends to absorb moisture and also is very soft, after repeated clean-outs of the grease trap the gasket needs to be replaced.  Overall the Grease Trap Interceptor works perfect and will last many years with proper maintenance. I have and will continue to send my commercial kitchen owners to Prima for equipment.
