Overview
VEVOR offers compact carbon‑steel grease interceptors in three capacities: 8 lb, 30 lb and 40 lb. Each is a side‑inlet, under‑sink style designed to separate oil and grease from wastewater before it reaches the drainage system.
The smallest model is intended for light domestic or low‑volume commercial use, while the 30 lb and 40 lb units handle progressively higher flow rates and hold more grease between maintenance intervals. All three share the same basic construction material (Q235 carbon steel) and similar inlet/outlet sizing.
Key differences to weigh are the flow rate (4.64, 10.81 and 15.23 GPM respectively), the external footprint and the service weight — factors that affect where the unit will fit and how often you’ll need to clean it out.
This page compares practical points — capacity, typical use‑case, installation footprint and maintenance considerations — to help restaurant owners, caterers and busy householders choose the most appropriate model for their sink setup.

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 8 lb grease trap is an under‑sink, side‑inlet interceptor made from Q235 carbon steel. It provides basic oil‑water separation with a modest 4.64 GPM flow rate and a small footprint that fits tighter installations. The unit is intended for light commercial or heavy domestic use where grease output is relatively low. Sealing and construction are presented as reliable, and the unit is straightforward to service — however, capacity is limited compared with larger models, so frequent cleaning is necessary in busier kitchens. Check inlet/outlet sizes to ensure compatibility with your existing plumbing.
Key features
- Capacity: 8 lb grease holding
- Flow rate: 4.64 GPM
- Material: Q235 carbon steel
- Inlet/outlet size: 1.89 in (48 mm)
- Footprint: compact under‑sink dimensions (305x290x390mm)
- Weight: approximately 9.1 kg (20.06 lbs)
#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 VEVOR 30 lb grease interceptor ups capacity and flow for medium‑duty kitchens. Built from Q235 carbon steel, it offers a 10.81 GPM flow rate and a larger holding volume to reduce how often you need to remove accumulated grease. The increased dimensions and weight mean it requires more under‑sink space or secure mounting, but it’s still designed for under‑sink installation. This model suits small restaurants, cafés and catering operations that produce steady grease loads and want a practical, serviceable interceptor without moving to a floor‑mounted or external system.
Key features
- Capacity: 30 lb grease holding
- Flow rate: 10.81 GPM
- Material: Q235 carbon steel
- Inlet/outlet size: 1.89 in (48 mm)
- Footprint: medium dimensions (600x400x420mm)
- Weight: approximately 17.8 kg (39.24 lbs)
#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 VEVOR 40 lb grease interceptor is the largest of the three and provides the highest flow rate (15.23 GPM) and grease holding capacity. Constructed from Q235 carbon steel, it’s aimed at busy commercial kitchens and catering operations that require robust oil‑water separation and less frequent servicing. Its larger dimensions and heavier weight mean careful planning for installation: you’ll need sufficient under‑sink space, structural support and plumbing alignment. This unit is useful where a compact external interceptor isn’t feasible but a high‑capacity under‑sink solution is required.
Key features
- Capacity: 40 lb grease holding
- Flow rate: 15.23 GPM
- Material: Q235 carbon steel
- Inlet/outlet size: 1.89 in (48 mm)
- Footprint: large dimensions (650x450x460mm)
- Weight: approximately 21.9 kg (48.28 lbs)
Buying guide
Choose capacity to match how much greasy effluent your sink produces: small domestic or light prep kitchens can manage with an 8 lb trap, cafés and medium kitchens usually need 30 lb, and busy commercial kitchens should consider 40 lb. Check the unit’s flow rate against your sink or appliance discharge rate and confirm inlet/outlet sizes to match existing plumbing. Measure under‑sink space and weight limitations — larger units are heavier and may need floor or wall support. Factor in cleaning frequency: bigger capacity generally means fewer emptying cycles, but all units require periodic grease removal to remain effective. Finally, confirm local regulations for grease interceptor sizing and installation, and check whether an external or below‑floor interceptor is required for high volumes.
FAQs
How often should a grease trap be emptied?
Emptying frequency depends on use. Light domestic use might need cleaning monthly, while busy restaurants may need weekly or more frequent servicing. Follow the 25%‑full guideline and local rules.
Can these VEVOR units be installed under any sink?
They are designed for under‑sink installation but you must check space, weight capacity and matching inlet/outlet sizes. Larger models may require additional support or floor placement.
Do they require special tools to maintain?
Regular maintenance is manual removal of accumulated grease and cleaning the internals. Basic tools and protective equipment (gloves, bucket) are usually sufficient.
Our recommended choice
For most small commercial kitchens and serious home users looking for the best balance of size, performance and value, the 8 lb model is a sound starter option. If you regularly prepare high volumes of fatty foods, step up to the 30 lb or 40 lb model to reduce maintenance frequency and avoid blockages.
