The TZ-1826-SSA 100 GPM (6.31 l/s) Above-Ground Trapzilla99 Grease Interceptor is ASME/PDI rated for 100 GPM (6.31 l/s) and holds more than 1,826 pounds (248 Gallons) of grease in a 274-Gallon footprint. Unlike traditional interceptor designs, the TZ-1826-SSA is capable of holding more than 90% of its internal volume in grease and solids before it begins to lose efficiency. Perfect for replacing failing steel or concrete, the TZ-1826-SSA is manufactured out of durable polyethylene, meaning that it will outlast traditional interceptors made of inferior materials. The above-ground model comes with the SSA-1826 Support Stand, an 18" (457mm) long single-piece extension collar and 22" (558mm) Solid Top Cover that can be removed easily to clean out retained grease, and an external support frame.
