A misconception concerning grease traps is that they are "simply helpful" like recycling is "helpful.” This couldn't be farther from the truth. While recycling is helpful, a grease trap is essential if you have a store that produces grease at all. Blocked drains can cause trouble for store owners and their surrounding neighbors. Don’t get caught with fines you can’t pay and customer loss from all the harm caused. Atlantic Metalworks’s GI-50 grease interceptor is great for stores with an overall higher output of water. With a 50 pound capacity and flow rate of 25 gallons per minute, you won’t need to worry about excess oils, fats or grease from blocking up your drains, or worse, main pipe lines. The Plumbing and Drainage Institute has continually given us their stamp of approval on our carbon steel constructed and guaranteed free of defects, Grease Traps. Call us if you have any questions.

Rated 5 out of 5 by from The grease trap is legit!! I purchased a 50lb grease trap from Prima Supply for our juice bar (Quench Juicery in Scituate, Ma). It was very reasonably priced and is ROCK solid. I'd definitely order from Prima again!

How do I know what size to get.

Asked by: D Wms
A standard calculator for the gallons per minute you might need would be: ((length in inches) x (width in inches) x (depth in inches) x (number of bowls)) 231 x .75 = gallons per minute needed. Gallons per minute (GPM) doubled will equal the storage capacity of the unit. So a 50 GPM need will require a 100 pound unit. In this case, the formula would be (18 x 18 x 12 x 3) 231 x .75 = 37.87 gallons per minute, or about 80 pounds of storage. So the or would be the best options for you. While this is a decent formula, be sure to go to check with your local health inspector to ensure that the figure you come up with will meet the minimum that they will require.

is this for outdoor use

Asked by: don1025
The Atlantic Metalworks grease traps are primarily designed for indoor use. They can be installed outside but they will begin to rust and deteriorate quicker than in an indoors environment.
