Overview
VEVOR’s under-sink grease traps are built from Q235 carbon steel and use side inlets with similar 48 mm pipe sizes across the range. The models scale by internal capacity, external dimensions and rated flow rate, so the main trade-offs are grease holding capacity versus available under-sink space.
The 40 lb unit is the largest here, with the highest flow rating and a heavier, roomier body that suits busy commercial kitchens. The 30 lb model reduces footprint and weight but still covers many small commercial or high-demand domestic situations. The 8 lb model is compact and designed for low-flow situations such as a small café, concession or a home kitchen that still needs grease separation.
All three models share common design points: carbon-steel construction, user-friendly sealing and removable internals for maintenance. They’re intended as physical interceptors rather than active treatment devices, so regular cleaning and correct installation are essential for reliable performance.
When choosing, focus on three things: expected grease load (how much cooking oil and grease you dispose of), available space under the sink, and local regulations—some areas require specific certified interceptors or minimum capacities for businesses.

Detailed reviews
#1 VEVOR Commercial Grease Trap, 40 LBS Grease Interceptor, Side Inlet Interceptor, Under Sink Carbon Steel Grease Trap, 15.2 GPM Waste Water Oil-water Separator, for Restaurant Canteen Home Kitchen
This 40 lb VEVOR interceptor is the top-capacity option in the trio. Built from Q235 carbon steel, it’s designed as an under-sink, side-inlet grease trap with a 15.23 GPM rated flow. Its larger internal volume suits kitchens with consistently high grease output, helping reduce service frequency compared with smaller units. The unit uses standard 48 mm inlet/outlet ports and includes a sealing design intended to keep odours down and simplify maintenance. Being the biggest model here, it needs the most under-sink space and is heavier to handle during installation.
Key features
- Primary material: Q235 carbon steel
- Grease capacity: 40 lb (approx.)
- Rated flow: 15.23 GPM
- Inlet/outlet size: 1.89 in (48 mm)
- Product dimensions: 650 x 450 x 460 mm
- Weight: ~21.9 kg
#2 VEVOR Commercial Grease Trap, 30 LBS Grease Interceptor, Side Inlet Interceptor, Under Sink Carbon Steel Grease Trap, 10.8 GPM Waste Water Oil-water Separator, for Restaurant Canteen Home Kitchen
The 30 lb VEVOR grease trap is a compromise between capacity and space. It keeps the same Q235 carbon-steel build and 48 mm inlet/outlet sizing but reduces the external dimensions and weight compared with the 40 lb model. With a 10.81 GPM flow rating it suits many small commercial applications and higher-demand domestic kitchens that produce moderate grease volumes. Design features mirror the larger model: removable internals for cleaning and sealing intended to reduce odour.
Key features
- Primary material: Q235 carbon steel
- Grease capacity: 30 lb (approx.)
- Rated flow: 10.81 GPM
- Inlet/outlet size: 1.89 in (48 mm)
- Product dimensions: 600 x 400 x 420 mm
- Weight: ~17.8 kg
#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 compact alternative for low-flow situations. It shares the same Q235 carbon-steel construction and 48 mm inlet/outlet sizes but comes in a much smaller footprint and lower weight. With a 4.64 GPM flow rating it’s best for single-sink setups, small cafés or homes where grease production is modest. The design aims to be user-friendly for cleaning and still offers a sealing approach to reduce odour, but it will require more frequent emptying in busier environments.
Key features
- Primary material: Q235 carbon steel
- Grease capacity: 8 lb (approx.)
- Rated flow: 4.64 GPM
- Inlet/outlet size: 1.89 in (48 mm)
- Product dimensions: 305 x 290 x 390 mm
- Weight: ~9.1 kg
Buying guide
Capacity vs. footprint: Choose a grease trap capacity that exceeds your typical daily grease output; undersizing causes frequent blockages and more maintenance. Flow rate: Match the interceptor’s GPM rating to the busiest sink or combined sinks it will serve. Installation: Check inlet/outlet sizes and clearance under your sink; you may need adaptors or additional pipework. Maintenance: Plan for regular emptying and cleaning — the interceptor is a passive device and performance drops as it fills. Material and durability: Carbon-steel bodies are robust but check for internal coatings or maintenance recommendations to avoid premature corrosion. Local rules: Commercial kitchens often face local regulations on interceptor size, servicing frequency and waste disposal—confirm before purchase.
FAQs
How often should a grease trap be emptied?
Frequency depends on capacity and use. For commercial kitchens this can be weekly or more often; for lower-use environments it might be monthly. Empty before grease and solids significantly reduce capacity or cause odours.
Can I install a VEVOR grease trap under any sink?
Generally yes if inlet/outlet sizes match and there’s sufficient clearance. Check the unit dimensions and plumbing layout first; adaptors or rerouting may be needed for a neat fit.
Our recommended choice
For most small commercial kitchens and busy home setups that want a balance of hold capacity and flow rate, the 40 lb VEVOR model gives the most headroom and reduces cleaning frequency. If space or budget is tighter, the 30 lb model is a sensible middle ground; the 8 lb model is only suitable for low-flow situations.
