Beseder Grease Trap Plastic 5 GPM Under Sink
The Beseder under-sink grease trap is built from durable plastic with a 1/4″ wall thickness for long-lasting performance. Its compact footprint (15.75 inches by 13.2 inches by 10.63 inches) makes installation under sinks straightforward in home kitchens, food trucks, and small cafes. The 5 GPM capacity supports moderate wastewater loads, and its multistage cleaning system targets oils and emulsified fats to prevent blockages and grease-related drainage issues. The plastic construction resists rust and corrosion, reducing the risk of leaks over time.
BEAMNOVA 8lbs Commercial Grease Trap Stainless Steel Interceptor
BEAMNOVA’s upgraded stainless steel grease trap offers a robust design with an integrated outlet pipe, manual, and necessary accessories. The unit emphasizes precise welding and a sealed rubber ring to minimize leakage, alongside rounded corners to prevent injuries or scratches during handling. Its practical operating principle keeps fats, oils, and greases on the water’s surface while solids settle, with baffles controlling the outlet to prevent FOG from passing through. Dimensions of 14.17″ x 10.24″ x 9.45″ fit a range of under-sink configurations, and locking devices help prevent leaks on the sides.
BEAMNOVA Commercial Grease Trap 25lbs Stainless Steel
This larger BEAMNOVA model provides increased capacity for higher-volume kitchens. Constructed from heavy-duty 1.2mm 201 stainless steel, it resists rust and deformation while maintaining a long service life. The unit features an upgraded outlet design, rounded corners, and a rubber-sealed inner lid to prevent leaks. It is designed for easy installation under sinks, with straightforward piping from the sink and dishwasher to the inlet and from the outlet to the drain. A recommended fit for moderate to busy commercial kitchens seeking higher throughput without frequent maintenance.
Wadoy 8 lbs Commercial Grease Trap
Wadoy’s grease trap uses thickened 201 stainless steel for durability and features leak-preventing seals. The unit operates on the standard grease trap principle, allowing FOG to rise to the surface while solids settle, reducing the risk of drain blockages. The threaded drainage outlet ensures a secure connection with piping, and the lid includes a rubber sealing ring to further minimize leakage. With its compact form and efficient sealing, this model suits busy kitchens seeking reliability without bulky installation requirements.
HYITO Stainless Steel Interceptor For Restaurant
HYITO’s stainless steel grease trap emphasizes corrosion resistance and deformation resistance with 304-grade components. Its physical flow diversion and gravity sedimentation design separates grease from wastewater effectively, allowing only treated water to drain. The compact dimensions (13.9″ x 9.9″ x 9.8″) and a 1.5-inch drain outlet make it compatible with standard kitchen plumbing. This model balances durability and space efficiency, suitable for mid-sized restaurants, canteens, and cafe settings seeking reliable grease separation.
Buying Guide
- Material and Durability: Plastic units resist rust but may be less rigid than stainless steel. Stainless options offer higher durability and longer service life in high-load environments.
- Capacity and Flow Rate: Choose a unit that matches your kitchen’s wastewater load. Smaller homes can use 5–8 GPM units, while busy commercial kitchens may require 10–25+ GPM or higher capacity.
- Installation Space: Measure under-sink clearance and consider whether the unit’s footprint fits your cabinet or cabinet recess. Some models are deeper or taller than others.
- Sealing and Leakage Prevention: Look for rubber gaskets, sealed lids, and secure outlet connections to reduce odor and leaks.
- Maintenance and Access: Consider ease of cleaning, baffle design, and whether the unit offers easy access for periodic maintenance and removal of solids.
- Compliance and Compatibility: Verify compatibility with local plumbing codes and ensure the outlet and inlet sizes match your existing pipes.
- Installation Method: Some units arrive fully assembled; others require simple assembly and solvent-weld piping. Ensure you have appropriate tools and fittings.
- Cost of Ownership: While initial price matters, factor in maintenance frequency, cleaning requirements, and potential replacement intervals.
Choosing the right in line grease trap involves balancing capacity, durability, and installation practicality. The options above cover plastic and stainless steel, with capacities suitable for small to mid-size commercial kitchens and homes. When evaluating, consider peak wastewater volume, the types of grease and solids produced, and your local regulatory requirements to ensure optimal performance and compliance.
