OVERVIEW

SCIENTIFICALLY ENGINEERED For over fifty years, JAY R. SMITH MFG. CO.® has conducted hundreds of tests both in the laboratory and in the field, in order to offer efficient grease interceptors which have improved operational characteristics suitable for most applications. When designing our line of interceptors, we kept in mind the fact that these units must be for practical applications. As a result, the units embody practical features that make installation easier and also simplify cleaning and servicing. PLUMBING AND DRAINAGE INSTITUTE CERTIFICATION SEAL Many Smith Interceptors bear the certification seal of the Plumbing and Drainage Institute. Ratings shown in the catalog conform with the rigid standards established by the Institute. This seal on Smith Grease Interceptors is your guarantee that the designs and ratings have met or surpassed all standards established by the Institute. PRACTICAL FEATURES The one piece cover used on SMITH Interceptors is equipped with a single lock and lift ring (two on large sizes). No bolts or nuts to get lost or wrenches to look for . . . the locking device is a practical feature of the cover assembly. A soft, flat or round neoprene gasket is firmly attached to the body of all interceptors. This eliminates the gasket tearing loose every time the cover is removed. Interceptors have an air relief to eliminate the possibility of siphonage, and are furnished with a separate flow control device to insure the interceptor will function within its rated capacity.

APPLICATION A Grease Interceptor is necessary where grease, fats, oils or other similar line clogging contaminants are present in waste water that must be disposed of through the sanitary system. Preventing grease from entering drainage lines should always be considered when designing the plumbing drainage system in any restaurant, cafeteria, hotel, school, hospital, institutional or commercial building having facilities for the preparation and serving of food in quantity. In these installations, as well as in commercial food processing plants, dairies, and other industries where greases and fats are a by-product, an efficient SMITH interceptor should be installed to prevent this material from entering the drainage lines. HOW THE INTERCEPTOR OPERATES Water draining to the interceptor passes through a flow control fitting which regulates the velocity of the water to the capacity of the interceptor. As the water enters the interceptor at this controlled rate of flow it is free of turbulence. It then passes over a series of separator baffles which are strategically located to insure that greases, fats and oils are efficiently separated from the waste water. Once separated, these contaminants rise to the surface of the water in the interceptor by natural flotation and are accumulated until removed. The waste water now relieved of over 90% of the contaminant oils and greases, continues to flow through the interceptor into the sanitary system.
