What is an automatic grease separator

Knowing your automatic from a semi-automatic grease separator

Grease Guardian explains the difference between automatic grease separators and "semi-automatic" grease traps. This article helps the end-user to choose which technology better suits their type of kitchen activity and get some sense out of what can be a very confusing market.

In today’s commercial kitchen environment, choosing the right grease trap is about more than ticking boxes for compliance. It’s about ensuring consistent performance, reducing operational costs, and safeguarding your drainage system. The term “automatic grease trap” or “automatic grease removal device” gets used often — but it’s not always correct.

At first glance, many grease management systems on the market appear to be automatic. They might plug in, or even have timers. But what’s often overlooked is how these systems actually handle grease and whether they truly remove fats, oils, and grease (FOG) from wastewater…..The reality is that many of these units are semi-automatic at best, relying on passive separation methods that don’t stand up to the real-world conditions of a busy kitchen.
