OVERVIEW
***NEXT WORKING DAY DELIVERY***
The popular large under sink grease trap measures 550mm x 450mm x 325mm high. Made from robust 304 stainless steel, our GT80 is sized for up to two commercial sink bowls.
This can trap be fitted easily underneath a sink, as with all sizes we recommend you check the space in and around your sink ensuring sufficient clearance for opening and regular cleaning.
Using simply the gravitational flow of water, this stainless steel fat trap channels the water inside the chamber. This cools the water and aids separation of fats, oils and grease (FOG’s). Safer ‘grey water’ continues and exits in to your drains whilst the FOG’s are retained in the trap for collection. This easy to fit grease trap can be installed by a local qualified plumber.

Efficient Gravity-Fed Operation
This large grease trap is powered entirely by gravity. Wastewater flows into the trap and is directed through internal baffles that slow the flow and help the water cool naturally. As this happens, fats, oils and grease rise to the top and are retained inside the trap while cleaner water exits safely.
With no electrical parts or mechanical components, this passive system is cost-effective to run, simple to maintain and flexible in terms of installation location.
How Many Meals Per Day?
Our large grease traps are engineered to handle high kitchen output. This 80 litre model is ideal for commercial settings producing between 100–150 meals per day. The internal baffle system ensures wastewater is channelled correctly, allowing effective separation and preventing slow drainage or backups.
If your water provider has requested a minimum 100 litre grease trap, we also offer larger models suitable for high-demand kitchens.
