Overview
All three VEVOR units here are under‑sink carbon‑steel grease traps intended for light commercial use. They follow the same basic side‑inlet design and use internal baffles to separate oil and grease from wastewater before it goes to the drain.
The main differences are capacity and flow rate. The 8 lb model is compact and best where space is tight and grease output is low. The 30 lb and 40 lb models increase capacity and flow handling, which reduces cleaning frequency for busier kitchens.
Material and port sizes are consistent across the range: Q235 carbon steel construction and 48 mm (1.89 inch) inlet/outlet sizes. That makes swapping one model for another straightforward where plumbing sizes match.
When choosing, consider your peak flow from sinks and dishwashers, how often you can physically clean and dispose of collected grease, and whether the trap will fit under the available sink space.

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
The 40 lb VEVOR grease interceptor is built for small commercial operations that produce a moderate amount of fat, oil and grease. With a reported flow rate of about 15.23 GPM and a sizeable internal capacity, it reduces how often you need to empty the unit compared with smaller under‑sink traps. Constructed from Q235 carbon steel, it uses a side‑inlet configuration and standard 48 mm inlet/outlet fittings, so it integrates with common plumbing layouts. The lid and sealing design aim to keep odours contained and permit straightforward access for manual cleaning. Because it's larger and heavier than compact models, check under‑sink clearance and support before installation.
Key features
- 40 lb grease holding capacity
- Flow rate around 15.23 GPM
- Side‑inlet under‑sink design
- Q235 carbon steel construction
- Inlet/outlet: 48 mm (1.89 in)
- Product dimensions: 650 x 450 x 460 mm
#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 mid‑capacity interceptor intended for kitchens that produce a steady but not excessive amount of grease. With a flow rate near 10.81 GPM it handles moderate sink and prep area drainage without demanding the space of the larger 40 lb unit. It shares the same Q235 carbon steel construction and 48 mm inlet/outlet fittings as the other models, which helps if you standardise equipment across sites. The unit's size balances easier installation and handling with a worthwhile grease holding volume, making it a practical choice where cleaning can be scheduled weekly or biweekly depending on use.
Key features
- 30 lb grease holding capacity
- Flow rate around 10.81 GPM
- Side‑inlet under‑sink layout
- Made from Q235 carbon steel
- Inlet/outlet: 48 mm (1.89 in)
- Product dimensions: 600 x 400 x 420 mm
#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 option for kitchens that generate only a small amount of grease or for temporary/portable operations where space is constrained. Its lower flow rate and smaller capacity mean it needs more frequent emptying in busier conditions, but it is easier to position under a sink and is lighter to handle at installation. As with the other models it uses Q235 carbon steel and standard 48 mm inlet/outlet sizing, so it can be retrofitted where those plumbing dimensions match. This model is a cost‑effective starting point for tiny operations, but plan on closer maintenance intervals.
Key features
- 8 lb grease holding capacity
- Flow rate around 4.64 GPM
- Side‑inlet under‑sink format
- Q235 carbon steel body
- Inlet/outlet: 48 mm (1.89 in)
- Product dimensions: 305 x 290 x 390 mm
Buying guide
Match capacity to workload: estimate typical daily grease by menu and washing volume and allow extra capacity for busy periods. Check the trap flow rate (GPM) against the combined flow from your sinks and appliances. Measure under-sink clearances and confirm inlet/outlet sizes. Prefer a model with straightforward access for cleaning and a reliable sealing lid. Carbon steel is common and durable but ensure the unit will be accessible for regular maintenance and local waste disposal rules.
FAQs
How often should I clean an under‑sink grease trap?
Cleaning frequency depends on capacity and grease load. Small 8 lb units may need emptying weekly in busy kitchens, while larger 30–40 lb units can go longer. Inspect regularly and follow local regulations.
Can I install a grease trap myself?
Basic plumbing skills might suffice for replacement under‑sink traps, but check local codes. Professional installation ensures correct slope, seals and compliance with regulations.
Our recommended choice
For most light commercial kitchens the 40 lb VEVOR model balances capacity and flow rate, cutting maintenance without taking too much under‑sink space. Smaller sites or tight spaces should consider the 8 lb or 30 lb models based on expected grease production.
