Made from catering grade 304 stainless steel this domestic sized small Grease Trap is our entry-sized model measuring just 380mm x 275mm x 230mm.  Small grease traps are ideal for fitting in tight spaces and under sinks where you still want to help catch unwanted fats, oils and grease (FOG’s) which otherwise block your drains.  

This GT5 20 litre stainless steel small grease trap is considered suitable for a single, domestic-sized sink bowl or low use establishments producing 1-49 meals per day.  

With no need for electricity, this ‘passive’ or ‘gravity’ grease trap is incredibly cost effective and works entirely using the flow of water. Incorporating a food debris basket underneath the inlet to catch small food particles, carefully positioned baffle panels then help to quickly cool wastewater aiding the separation process.  

Separated FOG’s are retained in the central collection chamber and cleaner or ‘grey’ wastewater continues to flow through the outlet in to the drainage system.  It is recommended to drain off accumulated FOG’s fortnightly.

Under Sink Stainless Steel Small Grease Trap

All of our under sink grease traps are made from catering grade 304 stainless steel. This GT5 is our starter small grease trap and it is designed to be fitted easily under a sink.  

It can be very easy to think of fats, oils and grease build-up as unlikely to cause immediate drain problems. However, many food service establishments still are unaware it is mandatory to have a grease management system in place. Otherwise, they can face hefty fines.  

Installing a grease trap can help you remain on the right side of water regulations. If you’re a business owner or member of staff responsible for your kitchen operations, consider reading more about compliance here. Furthermore, when purchasing a small grease trap, consider a safe, natural grease trap cleaner

Grease Trap Store’s passive or gravity small grease traps can be vital. They can control where cooking fats, oils and grease end up.  This, in turn, helps maintain hygiene standards by ensuring your drains are continue free-flowing.  

Our Grease Traps come in a range of sizes and are gravity-fed. Furthermore, this means they work effectively using entirely the flow of water!  Grease traps that don’t require electric power are not only cheaper to purchase. However, it also means they are versatile and practically free to ‘run’.  Having only to pipe ‘downhill’ using the benefit of gravity, this is considered the most reliable and cost-effective method in grease management.   

Commercial Grade

By choosing a commercial grade, passive grease trap you can easily capture waste fats, oils and grease (FOG’s).  When connected to your sink or dishwasher, this helps channel waste water through the grease trap using a number of carefully positioned panels which helps cool and thereby separate FOG’s from the water.  

Deciding on and choosing a correctly sized small grease trap enables your sink and drain system to flow easily and without backing up.  A well sized and well functioning small grease trap accommodates the flow of your sinks and simultaneously ‘catches’ the grease inside the central chamber, seamlessly.  If you have a double bowl commercial sink then consider a larger 80 litre grease trap such as the GT18 or our under sink 100ltr GT26

Cost Effective Grease Management

All of our small under sink grease traps are both designed and supported by our customer service in the United Kingdom.  

In order that you can frequently and easily empty your small grease trap, we have added a drain off valve at either end directly underneath the inlet and outlet.  This helps you quickly and fully drain off the accumulated wastewater and food sediment when beginning a full clean.  

Check out the New Valves

Additionally and new to 2023, our redesigned small grease trap now has a third, higher up side valve which along with the high quality brass tap valve, enables rapid drain off of captured FOG’s. This can help extend the time between full deep cleans.
