Overview
These three VEVOR grease interceptors are similar in design and materials but differ mainly in capacity, flow rate and physical size. All are side-inlet under-sink units made from Q235 carbon steel with the same inlet and outlet sizes, so plumbing connections are consistent across the range.
The 40 lb model handles the highest flow and stores the most grease, making it suitable for busier kitchens or where longer intervals between emptying are needed. The 30 lb option is a mid-point for small cafés or busy home kitchens with moderate use. The 8 lb trap is compact and aimed at low-volume sinks or limited under-bench spaces.
When choosing, consider how often you can clean the trap, whether you have room under the sink for the footprint listed, and the maximum flow your sink(s) will produce. Local regulations may also dictate minimum interceptor sizes or servicing schedules, so check with your commercial waste or environmental officer.
All three models share practical features such as user-friendly lids, reliable sealing designs and a focus on space-saving installation. The key differences are capacity, weight and flow rate — pick the smallest unit that still meets your peak flow and grease-holding needs.

#3 VEVOR Commercial Grease Trap, 8 LBS Grease Interceptor, Side Inlet Interceptor, Under Sink Carbon Steel Grease Trap, 4.6 GPM Waste Water Oil-water Separator, for Restaurant Canteen Home Kitchen
The 8 lb VEVOR grease trap is the smallest of the three, aimed at minimal-footprint installations where grease output is low. Its compact dimensions make it a practical choice for kiosks, small food stalls or domestic sinks with limited under-bench room. With a 4.64 GPM flow rate and the same 48 mm connection size, it fits standard plumbing but holds much less grease than the larger models, meaning more frequent servicing. It offers the same basic construction and sealing approach as its larger siblings but is best suited to light-duty use.
Key features
- Capacity: 8 lb grease holding
- Flow rate: 4.64 GPM (approx)
- Material: Q235 carbon steel body
- Inlet/outlet: 48 mm / 1.89 in side connections
- Dimensions: 305 x 290 x 390 mm (compact footprint)
- Weight: around 9.1 kg (20.06 lbs)
Buying guide
Match capacity to usage: larger kitchens and multiple sinks need higher-capacity traps and higher flow ratings. Check the unit footprint against available under-sink space and confirm inlet/outlet sizes match existing plumbing (these models use 48 mm / 1.89 in). Plan for maintenance: grease traps need regular emptying and cleaning — choose a size that keeps servicing practical for your schedule. Consider material and build: carbon steel is robust but may need care in corrosive environments. Finally, always confirm local regulations for interceptor sizing and disposal.
FAQs
How often should a grease trap be emptied?
Frequency depends on usage and capacity. Busy kitchens may need weekly emptying, smaller units can be monthly. Inspect regularly and empty before grease reaches the outlet baffle.
Can I install these traps under any sink?
They are designed for under-sink installation with side inlets and a 48 mm (1.89 in) connection. Check the unit dimensions against your cabinet space and ensure the inlet/outlet align with your plumbing.
Our recommended choice
For most small commercial kitchens that want fewer maintenance visits while keeping a compact footprint, the 40 lb VEVOR trap offers the best balance of capacity and flow. For tighter spaces or very low-volume sinks, the 8 lb model can be a practical, low-cost option.
