OVERVIEW
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 GT20 is a compact, 20 litre stainless steel small grease trap 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 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 regularly.

Compact and Cost-Effective Drainage Protection
This small grease trap is an essential addition for cafés, small takeaways, mobile food units and other low-volume kitchens that require dependable FOG control. Although compact, the GT20 offers excellent separation efficiency and helps prevent the recurring blockages that can disrupt service and increase maintenance costs.
Because it is a passive, gravity-fed system, there are no electrical components or costly consumable filters. This makes the unit inexpensive to run and easy to position beneath most standard commercial sinks.
How It Works
Wastewater passes through internal directional baffles that help slow and cool the flow. As the water cools, fats, oils and grease naturally rise and remain inside the trap while cleaner water exits safely. The result is a simple yet effective system that keeps your drainage free-flowing and supports compliance with Building Regulations Part H.
Choosing the correct size is important. A small grease trap like this is perfect for single-sink setups, but larger sinks or commercial dishwashers will require a bigger capacity. For double bowl sinks or higher meal output, view our larger units such as the GT80 or 100 litre stainless steel models.
Designed for Practical Maintenance
To support easy cleaning, this small grease trap includes two drain valves that allow quick release of wastewater. Periodic checks and routine emptying ensure the trap continues performing at its best. Whether emptied in-house or by a grease trap maintenance company, always dispose of FOG waste according to local authority requirements.
Fast Delivery & UK Compliance
This small grease trap is stocked and supported in the UK, dispatched quickly through our delivery partners, and complies with Building Regulations Part H (2.21). With its stainless steel construction and five-year warranty, it provides a dependable, long-lasting solution for any small commercial kitchen.
