Overview

All three models are manufactured from Q235 carbon steel and use a side-inlet design intended for under-sink installation. The main distinction between them is capacity and flow rate: the 8 lb handles small-volume outlets, while the 30 lb and 40 lb versions suit busier sinks or clusters of sinks.

Choosing the right interceptor comes down to estimating peak flow and how much grease your operation produces. A small café or prep sink may be fine with the 8 lb unit, whereas a full-service kitchen or shared plumbing bank usually needs the larger 30 lb or 40 lb units to avoid frequent emptying.

These units are space-saving compared with large in-ground or floor-mounted interceptors, but they still require routine maintenance: skimming trapped grease, checking seals and ensuring inlet/outlet connections match your plumbing.

Always confirm local plumbing codes and grease disposal rules before buying. Also check the retailer page for up-to-date dimensions, warranty details and shipping options so you can plan mounting and service access.

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

The VEVOR 8 lb grease trap is a compact under-sink interceptor built from Q235 carbon steel. It’s intended for small commercial applications where space is tight and grease production is modest. With a 4.64 GPM flow rating and 48 mm inlet/outlet ports, it fits many standard under-sink layouts. The unit emphasises a simple, user-friendly design and reliable sealing to limit leaks. Because capacity is limited, it suits single-sink prep areas or small cafés that can commit to regular emptying and maintenance.

Key features

  • Primary material: Q235 carbon steel
  • Rated flow: 4.64 GPM (approx.)
  • Inlet/outlet size: 48 mm (1.89 in)
  • Compact dimensions: suitable for constrained under-sink spaces
  • Side inlet design for typical sink plumbing
  • Model number: YSFLQKQ36*29*39

#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 trap boosts capacity and flow over the 8 lb model while retaining the same basic carbon-steel construction and side-inlet layout. Its 10.81 GPM rating and larger internal volume reduce how often you need to empty the unit, making it a sensible choice for small restaurants, food trucks with fixed prep sinks, or kitchens with multiple low-flow outlets. At roughly 600x400x420 mm it requires more under-sink clearance but still aims to be a compact alternative to floor-mounted interceptors.

Key features

  • Primary material: Q235 carbon steel
  • Rated flow: 10.81 GPM (approx.)
  • Inlet/outlet size: 48 mm (1.89 in)
  • Model number: YSFLQKQ60*40*42
  • Product weight ~17.8 kg for a stable footprint
  • Dimensions around 600x400x420 mm for increased capacity

#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 largest of the trio, designed for operations where grease generation and peak flow are both substantial. With a 15.23 GPM rating and a larger internal volume, it cuts the number of service visits and helps avoid frequent interventions. It’s manufactured from Q235 carbon steel and keeps the same side-inlet, 48 mm port sizing, but requires significant under-sink clearance and careful planning for installation and future servicing.

Key features

  • Primary material: Q235 carbon steel
  • Rated flow: 15.23 GPM (approx.)
  • Inlet/outlet size: 48 mm (1.89 in)
  • Model number: YSFLQKQ65*45*46
  • Product weight ~21.9 kg for stability
  • Dimensions around 650x450x460 mm for maximum under-sink capacity

Buying guide

Key considerations: capacity (how much grease your service produces and how often you want to empty the unit); flow rate (must match sink discharge rates to avoid backups); footprint (measure under-sink clearance and access); inlet/outlet size and position (these VEVOR units use 48 mm in/out ports but confirm on the product page); material and seal quality (carbon steel with reliable gaskets is standard for these models). Maintenance tips: schedule regular grease removal, use a labelled waste container for disposal, and inspect seals and fastenings during each clean to avoid leaks.

FAQs

How often should a grease trap be emptied?

Frequency depends on usage and capacity; small operations may need weekly emptying, busier kitchens fortnightly or monthly. Monitor grease level and local regulations—never let grease exceed recommended capacity.

Can these VEVOR traps connect to standard sinks?

The listed units use 48 mm (approximately 1.89 inch) inlet/outlet ports. Verify plumbing fittings and, if necessary, use compatible adaptors or consult a plumber for correct connections.

Our recommended choice

For most small commercial kitchens the 30 lb model balances capacity and size most effectively, cutting down on emptying frequency while still fitting under many sinks. If you run limited prep only, the 8 lb will save space; for higher-throughput kitchens pick the 40 lb.
