Commercial Grease Interceptor Trap 20 lb – Beseder
The Beseder grease trap is designed to fit under-sink configurations with convenient overall dimensions of 19.3 inches by 17.3 inches by 16.1 inches. Constructed with thick plastic walls, it resists rust, corrosion, and leaks—addressing common failure points in metal units. The multi-stage cleaning system supports effective treatment of various oily waters, including mineral, animal, and vegetable oils as well as emulsified fats and greases. A 10 GPM capacity makes it suitable for moderate to high-volume kitchens that want a compact, durable interceptor.
Key features summarized: high-grade plastic walls with 1/4″ thickness for durability, manageable under-sink dimensions, and a multistage cleaning system designed to handle diverse oil-water mixtures. The plastic construction reduces the risk of rust and corrosion, a common issue in metal traps in humid commercial environments.
Wentworth 40 Pound Commercial Grease Trap Interceptor for Restaurant Under Sink
The Wentworth grease trap delivers higher capacity with robust construction. Its 24.5″ L x 15.9″ W x 15″ H dimensions fit under counter spaces, while a 11-gauge (1/8″) steel body provides heavy-duty performance. The heavy-duty anti-corrosion powder coating protects against rust, making it a reliable choice for bustling restaurants that process large volumes of oily water. This unit emphasizes durability and long service life suitable for high-traffic kitchens.
Considerations include installation space, required plumbing connections, and the need for durable coatings in damp environments. Wentworth’s steel design offers strength, but may require more careful handling during maintenance and installation compared to plastic models.
BEAMNOVA Commercial Grease Trap 25lbs Stainless Steel Interceptor
BEAMNOVA’s 25-pound stainless steel interceptor emphasizes a fully equipped package with an outlet pipe, user manual, and all necessary accessories. The upgraded welding, rounded corners, and rubber-sealed connections aim to minimize leakage and simplify installation. The unit uses 1.2 mm stainless steel for durability and corrosion resistance, making it suitable for kitchens that demand a sturdy, leak-proof solution with straightforward maintenance.
Installation considerations include ensuring a flat floor for the trap and secure pipe connections. The stainless build supports longevity in busy environments and reduces maintenance frequency compared to lighter materials.
VEVOR Commercial Grease Trap, 40 LBS Interceptor
VEVOR’s 40-pound grease trap features a dual-path filtration design aimed at enhancing filtration efficiency. It supports a high flow rate up to 9.96 GPM per minute, enabling continuous operation without grease buildup. The unit uses a 1.2 mm stainless steel body, incorporating rust and deformation resistance as well as easy cleaning. A threaded outlet, rubber seals, and buckle-lock features contribute to a dependable seal against leaks in commercial plumbing systems.
This model suits mid-to-large kitchens seeking robust filtration and reliable performance, with emphasis on secure seals and long service life in demanding environments.
BEAMNOVA 8lbs Commercial Grease Trap Stainless Steel Interceptor
This compact BEAMNOVA model offers an 8-pound capacity suitable for small kitchens or auxiliary prep areas. The unit uses 201 stainless steel with corrosion resistance and includes practical features like a threaded outlet connection, rubber seals, and a locking design to minimize leakage. A lifting handle aids portability for quick service-area changes or cleaning tasks.
The operating principle centers on separating fats, oils, and greases by density—FOG rises to the surface while solids settle. The design focuses on providing a reliable, space-efficient option for kitchens where space is at a premium and simpler maintenance is preferred.
Buying Guide: Key Purchase Considerations And Comparisons
- Capacity and flow: Match the unit’s GPM rating to your kitchen’s wastewater volume. Higher-traffic restaurants benefit from larger capacities (20 GPM or more) to prevent system backups during peak hours.
- Material and durability: Plastic traps resist rust and corrosion and are lighter for installation, while stainless steel and carbon steel traps offer superior strength and longevity in busy environments. Consider climate, humidity, and cleaning frequency when choosing.
- Sealing and leak prevention: Look for rubber gaskets, threaded connections, and buckle-lock designs that provide secure seals. Proper sealing reduces odors, leaks, and maintenance needs.
- Ease of installation and maintenance: Pre-assembled units, accessible access ports, and clear installation instructions save time. Pick models with straightforward cleaning routines and readily available replacement parts.
- Footprint and fit: Ensure the unit’s dimensions fit under sinks or in the designated space. Some models offer compact footprints suitable for smaller kitchens while maintaining required capacity.
- Installation environment: For coastal or humid locations, corrosion resistance is critical. For high-volume canteens, heavy-duty steel with protective coatings provides longer service life.
- Maintenance considerations: Check cleaning frequency, filter replacement needs, and whether the unit offers multi-stage filtration or dual-path designs to maximize grease capture and minimize clogs.
- Code compliance: Verify that the chosen grease trap meets local plumbing codes and health department requirements to avoid compliance issues during inspections.
- Cost of ownership: Beyond upfront price, factor in installation cost, maintenance intervals, spare parts availability, and potential downtime during servicing.
Across these options, users should evaluate whether they prioritize under-sink compactness, high-volume capacity, or the durability of metal housings. Plastic models offer rust resistance and lighter handling, while stainless or carbon steel units emphasize longevity and rugged performance in busy restaurants. Your final choice should align with kitchen size, expected wastewater load, maintenance capability, and local regulations.
