The TZ-600 Trapzilla Grease Interceptor is ASME rated for 75 GPM (4.73 l/s) and holds more than 635 pounds (86 Gallons) of grease in a 95 Gallon footprint. This means that unlike traditional interceptor designs, the TZ-600 is capable of holding more than 91% of its internal volume in grease and solids before it begins to lose efficiency. Perfect for replacing failing steel or concrete, the TZ-600 is manufactured out of durable polyethylene, meaning that it will outlast traditional interceptors made of inferior materials. The basic models come with a Standard Adapter Ring lid and 22" Solid Top Cover that can be removed easily to clean out retained grease.
