Large Oil Interceptors

The solid baffle plate opposite the inlet to the oil interceptor diffuses the flow into the interceptor and lessens the turbulence of the oil-laden water as it enters the intercepting chamber. Solids and sludge carried in the water are stopped by the baffle and collected in the solids retaining bucket between the inlet and the flow-retarding baffle. Such accumulation can then be removed. The resulting quiet, even flow of water through the interceptor permits the oils and other light density substances to rise to the surface by the "flotation" principle of separation. Maximum separation and interception is affected in proportion to the elimination of turbulence of wastewater within the interceptor. The unique baffle/bucket design permits almost 90 percent of the interior of the interceptor to be used for the function of oil separation. They are constructed of 100% steel for long lasting performance and durability.

Installation Considerations:
Install the interceptor in the building sewer line. The interceptor may be set on the floor, partially recessed in the floor, top flush with the floor, or fully recessed below the floor to suit piping and structural conditions (click here for typical installation diagram). Be sure to anticipate sufficient clearance for removal of interceptor cover for cleaning. Also take into consideration the placement of flow control fittings, vent requirements, and draw-off piping.

These Interceptors are great for commercial and industrial applications such as: filling and service stations, maintenance garages, auto shops, airport hangars, laundries and cleaning establishments, parking facilities, machine shops, refineries, fabrication and welding plants and foundries.

These Oil & Sediment Interceptors Feature: an acid resistant coat on the exterior and interior, fabricated steel construction, bronze cleanout plug and visible double wall trap seal, removable sediment bucket, horizontal baffle, internal vent connection, with Dura-Coated heavy-duty cast iron grate.

These Oil Level Sensor Retrofit Kits Feature: a fiberglass sensor box containing an electronic oil level sensor, a fiberglass display box with one green power light, red oil level light, audible alarm, and junction box. To be used for retrofit applications on Zurn Z1186 and Z1188 oil interceptors. Power supply 120V (GFCI). Caution: Interceptor must be cleaned of solids and other debris and the sensors wiped off on a regular basis in order to ensure proper operation of the system. Z1194 must be used with interceptors for on-the-floor installation only.
