Best Commercial Grease Traps for Professional Kitchens
Every pot sink, prep sink, and commercial dishwasher sends fats, oils, and grease downstream. Cooled grease hardens inside the drain line, and the result is slow drains, odors, and backups that stop service. A correctly sized commercial grease trap captures it at the fixture, before it reaches your plumbing system, a septic field, or a wastewater facility.
The range runs from compact under-sink units rated at 4 GPM to large interceptors rated at 500 GPM, with grease capacities from 8 to 1,000 pounds.
We feature top-quality brands such as Watts, John Boos, and Omcan USA, and strive to provide the most competitive prices available.
Benefits of Grease Interceptors
A restaurant grease trap protects plumbing you have already paid for. Grease that never enters the line cannot solidify in it, which means fewer blockages and less reliance on drain cleaners and openers to reopen a blocked run.
Maintenance stays predictable. A removable baffle and a gasketed skid-proof cover let staff open the unit, skim it, and close it again quickly, and pairing the trap with floor troughs and drains keeps the wet side of the kitchen clean.
What to Look for in Grease Traps and Interceptors
Sizing comes first. Flow rate has to match the combined peak flow of every fixture draining into the unit, not just the largest one. Confirm what your local plumbing code requires before ordering.
- Flow rate: Rated in gallons per minute, from 4 GPM under a single sink to 500 GPM for high-volume kitchens.
- Grease capacity: Measured in pounds, from 8 up to 1,000, and it sets how long the unit runs between pump-outs.
- Material: Carbon steel bodies run about 1/8 inch thick, while epoxy coated units use cold rolled steel finished in an oven cured, acid resistant coating.
- Standard or semi-automatic: Semi-automatic models add a draw-off hose and an outlet shut-off valve so grease can be pulled off between service visits.
- Installation and connections: Some units can be floor mounted or recessed, with no-hub or threaded inlets and outlets sized to the drain line.
- Certification: Several standard traps are PDI certified, worth checking against what your inspector expects.
