Grease Separators

CONSTRUCTION

A compact, one-piece separator with integral extension built to exact requirements. The built-in strength of solid walls eliminates leaks caused by vibration and traffic in bolted down extensions.

Constructed of all-welded heavy gauge steel with corrosion-resistant coating, the separator features a removable nonskid flush-with-floor cover of heavy steel plate with leakproof and airtight gaskets, secured to the body of the unit with recessed stainless steel bolts, a removable separator screen and flow-regulator filter screen, a standard tapped inlet and outlet, and protective seal outlet. Concrete reinforcing anchor rings are optional.

Choice of outlet location saves space, labor, pipe and fittings. Outlet tee can be turned up to 90 degrees in either direction. Depth of inlet and outlet varies.

HOW TO ORDER

When an extension is needed to meet roughing-in on a flush-with-floor installation, select the separator of the right size and capacity. Then determine the required dimension A from the center of the outlet to the top of cover, and order accordingly. Dimension A is variable and can be specified to a fraction of an inch. The inlet opening is lower than the outlet opening to assure a wet inlet at all times. All separators with extensions have flush-with-floor covers.

NOTE: If dimension of extension A is not correct at Point of Order, built-on extensions available, priced on application.
