Overview: what matters when picking a grease interceptor
Grease traps capture fats, oils and grease (FOG) before they enter your drainage system. For small catering operations, cafés and shared or rental kitchens the right interceptor balances capacity, flow rate and footprint so it does the job without getting in the way.
These three VEVOR models share construction material (Q235 carbon steel), side inlet design and similar inlet/outlet sizing, but they differ in grease holding capacity, flow rate and external dimensions. That makes them a clear family of options to consider when you want the same basic design in different sizes.
Capacity is the deciding factor for most buyers: an 8 lb trap suits low-volume use or a single sink, while 30 lb and 40 lb units are aimed at busier prep areas or multiple sink runs. Think about peak flows, how often you can schedule emptying and whether you have the under-sink space for a larger body.
Also consider local regulations and disposal arrangements — some areas require certified traps or registered waste disposal procedures. Check the supplier’s full spec and your local plumbing codes before you buy.

Detailed reviews
#1 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
This compact VEVOR grease trap is the smallest in the family and is aimed at low-volume commercial kitchens or home-based catering. Built from Q235 carbon steel with a side inlet and a 48 mm inlet/outlet, it provides physical separation of oils and fats at a modest flow rate (4.64 GPM). Its smaller footprint makes it easy to install under many sinks, but capacity is limited so you should plan a regular emptying schedule. The unit’s sealing and user-oriented design simplify access for cleaning and maintenance. As with any grease interceptor, check local plumbing codes and disposal rules before installation.
Key features
- Material: Q235 carbon steel construction
- Grease capacity: 8 lb (approximate working capacity)
- Flow rate: 4.64 GPM (approx.)
- Inlet/outlet size: 1.89 in / 48 mm
- Compact dimensions: approx 305 x 290 x 390 mm
- Side inlet design for under-sink installation
#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 interceptor scales up the family design to serve busier small commercial kitchens. It keeps the same Q235 carbon-steel construction and 48 mm inlet/outlet while increasing grease capacity and nearly doubling the flow rate versus the 8 lb model. That makes it a sensible choice if you want to cut down on emptying frequency but still retain a manageable under-sink footprint. The larger body is heavier and needs more installation space; plan your pipe routing and check the unit’s dimensions before buying. As always, comply with local disposal and plumbing requirements.
Key features
- Material: Q235 carbon steel construction
- Grease capacity: 30 lb (approximate working capacity)
- Flow rate: 10.81 GPM (approx.)
- Inlet/outlet size: 1.89 in / 48 mm
- Dimensions: approx 600 x 400 x 420 mm
- Side inlet/under-sink orientation for kitchen install
#3 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
The 40 lb VEVOR grease trap is the top-capacity model in this range. With a 15.23 GPM flow rate and a larger body it’s aimed at kitchens that produce substantial grease and prefer longer intervals between emptying. It keeps the same construction and 48 mm port sizes as the smaller models, which simplifies pipework choices if you’re standardising across several sites. Expect a heavier installation and check that you have the clearance and structural support for a heavier unit. As with the other models, verify local compliance and disposal practice before purchase.
Key features
- Material: Q235 carbon steel construction
- Grease capacity: 40 lb (approximate working capacity)
- Flow rate: 15.23 GPM (approx.)
- Inlet/outlet size: 1.89 in / 48 mm
- Dimensions: approx 650 x 450 x 460 mm
- Side inlet style for under-sink or floor-mounted use
Buying guide
Key questions to help you decide: estimate your daily grease output (small café vs small restaurant), measure the available under-sink space, confirm required flow rate for your fixtures, and check local regulations on grease interceptor capacity and servicing. Smaller traps are cheaper and easier to install but need more frequent emptying; larger units need more room but reduce service visits. Prioritise an inlet/outlet that matches your pipework (the VEVOR family uses a 48 mm inlet/outlet) and choose carbon steel if you want a sturdy, budget-friendly material — but consider stainless for corrosive environments or longer-term durability.
FAQs
How often should I empty a grease trap?
Frequency depends on capacity and usage. Smaller traps can require weekly emptying in busy kitchens while larger units may be serviced monthly. Monitor accumulation and follow local regulations.
Can I fit these under a standard sink?
The 8 lb unit has the smallest footprint and will fit under many standard sinks. The 30 lb and 40 lb models are larger; measure available space and pipework clearance before buying.
Are VEVOR grease traps compatible with UK plumbing?
These models use a 48 mm inlet/outlet. You’ll usually need adaptors or local plumbing parts to match UK pipework. Check dimensions and consult a plumber if unsure.
Our recommended choice
For most small kitchens wanting a balance of cost, footprint and adequate capacity, the 8 lb model is the sensible entry point. If you expect higher grease volumes or want fewer service visits, step up to the 30 lb model; the 40 lb is best where space is available and grease loads are consistently high.
