Not ideal for: Small kitchens or operations with limited space and lower flow requirements
- Flow Rate:15.32 GPM
- Capacity:40 lbs
- Material:Carbon Steel
- Coating:Anti-Rust
- Inlet/Outlet Size:1.89 inches
Our verdict“This grease trap offers exceptional flow capacity and durability, making it perfect for high-volume commercial kitchens, despite some installation challenges.”
LYNICESHOP Commercial Grease Trap, 35L Oil-Water Separator for Restaurant and Kitchen
The LYNICESHOP model excels with its seven-stage filtration system, which ensures efficient separation of oil and water, preventing blockages and maintaining smooth drainage. Its capacity of 9.2 gallons and flow rate of 555 gallons per hour make it suitable for larger kitchen setups or industrial environments. The leak-proof double U interlocking design provides added security, and its straightforward installation appeals to operators seeking a reliable, maintenance-friendly option. However, its size and weight can be a drawback for smaller sinks or spaces, and regular cleaning is necessary to sustain filtration efficiency. Compared with the under-sink trap, it requires more space but offers more comprehensive separation, making it ideal for operations with strict wastewater standards or larger throughput.
Pros:- Effective seven-stage filtration system
- Leak-proof double U design for secure sealing
- High capacity suitable for demanding environments
- Easy to install and maintain
Cons:- Large size may be unsuitable for small sinks
- Heavy weight complicates installation

- Capacity:9.2 gallons
- Flow Rate:555 gallons/hour
- Dimensions:17.7 x 13.7 x 11.8 inches
Our verdict“This unit is tailored for environments needing rigorous separation and high capacity, although its size and maintenance needs make it less suited for smaller setups.”

How We Picked
Our selection process focused on identifying models with proven capacity and durability, suitable for commercial settings. We prioritized high flow rates, large capacities, and effective filtration systems, balancing these features against installation ease and maintenance needs. Each product was chosen for its distinct role—one for high-volume throughput and the other for thorough separation—ensuring options for different types of commercial operations.
Factors to Consider When Choosing Commercial Oil Water Separator
Choosing the right commercial oil water separator depends on your specific operational needs. Key considerations include flow rate, capacity, filtration efficiency, space constraints, and maintenance requirements. High-volume kitchens benefit from models with larger capacities and flow rates, while environments with strict effluent standards might prioritize advanced filtration. Understanding these factors can help you select a unit that balances performance, durability, and ease of installation.
Flow Rate and Capacity
For busy commercial kitchens, selecting a separator with a high flow rate—measured in GPM—is essential to handle large volumes of wastewater efficiently. Capacity, often expressed in pounds or gallons, determines how much waste the unit can hold before needing maintenance. Larger capacities reduce downtime but may require more space and installation effort.
Filtration System and Effectiveness
Filtration quality influences how well the separator prevents oil and solids from clogging drains. Units with multi-stage or specialized filtration systems—like the seven-stage setup of the LYNICESHOP model—offer superior removal but may involve more complex cleaning routines. Simpler models might be easier to maintain but less effective at thorough separation.
Installation and Space Requirements
Consider your available space and the complexity of installation. Under-sink models often feature threaded connections for quick setup, ideal for smaller or retrofit projects. Larger, free-standing units require more room and may need professional installation, which can add to overall costs. Weighing these factors ensures your chosen separator fits seamlessly into your operations.
Maintenance and Durability
Regular cleaning and maintenance are crucial to keep separators functioning optimally. Heavy-duty materials like carbon steel with anti-rust coatings extend lifespan, especially in demanding environments. Be prepared for cleaning routines—some units, like the LYNICESHOP model, need periodic filter cleaning to maintain efficiency. Consider how much time and effort your team can dedicate to upkeep when choosing a model.
Frequently Asked Questions
How often should I clean a commercial oil water separator?
The cleaning interval depends on usage volume and the specific model. Typically, high-capacity units like the LYNICESHOP may require cleaning every few months, while smaller or less-used models might need attention less frequently. Regular maintenance is essential to prevent clogs and ensure the separator continues to operate effectively.
Can I install a commercial oil water separator myself?
While some models are designed for straightforward installation, especially under-sink units with threaded connections, professional installation may be advisable for larger or more complex systems. Ensuring proper setup is critical to prevent leaks and guarantee optimal performance, particularly for units with higher flow rates and capacities.
What maintenance is required for these separators?
Maintenance typically involves regular cleaning of filters, emptying collected waste, and inspecting seals and connections for leaks. Some units feature easy-access components that simplify these tasks, but neglecting routine upkeep can lead to reduced efficiency or system failure. Follow the manufacturer’s guidelines for best results.
Are these separators suitable for industrial applications?
Yes, especially models with higher capacities and advanced filtration like the LYNICESHOP. They are designed to handle larger volumes of wastewater, making them suitable for industrial kitchens and processing plants. However, always verify the specific flow rate and capacity to match your operational demands.
What are the main differences between these two models?
The 15.32 GPM Grease Trap is optimized for high-flow, fast-paced kitchens requiring quick handling of wastewater with large capacity. In contrast, the LYNICESHOP unit excels in thorough oil-water separation thanks to its seven-stage filtration, making it better for strict compliance and larger-scale operations. Your choice depends on whether you prioritize capacity and speed or filtration precision.
Conclusion
If you operate a high-demand restaurant or food truck, the 15.32 GPM Grease Trap provides the capacity and durability needed to keep pace. For larger kitchens or facilities with strict wastewater standards, the LYNICESHOP model offers comprehensive filtration and higher capacity, though it requires more space and maintenance. Smaller setups or those with limited space should lean toward the under-sink option, while larger, industrial environments benefit from the robust features of the bigger separator.
