Ashland Poly Grease Traps / Interceptors

Lightweight grease removal systems for commercial/institutional kitchens

Proudly made in the USA
Many areas now require the use of a grease trap in any commercial food preparation situation. Ashland greasetraps are durable, lightweight, leak-proof, easy to handle and install. In many ways polyethylene is superior to metal, fiberglass, or specially treated materials that are promoted as preventing corrosion. Polyethylene grease traps include a completely integrated surface guaranteed not to corrode, chip, peel or leach. We recommend contacting your local health department for the code requirements in your area prior to ordering any greasetrap.

Frequently Asked Questions

Q. "How long should the holding time of the wastewater in the grease trap be?"
A. All of the grease traps that we offer come with flow control devices, so in most situations you shouldn't need to be concerned with that issue. The flow control limits the volume/speed and therefore creates the necessary holding time of the wastewater sitting inside of the greasetraps.

Q. "My local governmental code wants to know how long the water stays in the grease trap?"
A. Basically, the way some (many operate differently) health/safety/engineering departments figure the grease trap size needed is that they wish for you to keep the water in the trap for a certain period (length) of time. What that means is: If you have a 3 gallon per minute drain flow, and a 30 gallon grease trap, some agencies will consider the 3 gallons as having a 10 minute "hold" time. You calculate this by dividing the gpm by the gallon volume of the trap.

Not all governmental bodies operate the same way and so, please, contact them before you order a grease trap. Make certain that the size that you are ordering is the size that they will accept. Note that all grease traps have a maximum flow rate. Also note that for sanitation reasons, (all brands) grease traps are sealed and not open to the elements. Some brands of grease traps are difficult to open (not ours) but, in all cases, all grease traps are sealed. Again, generally (not always), the size of the grease trap versus the gallons per minute of your drainage is what determines the size that you are required to have. Please be certain of the size that is required by your local code or governmental regulatory agency prior to ordering. Shipping is very expensive for this product, and we do not accept returns on grease traps. When in doubt, do not order these until you are certain of what you need. The codes are designed to try to take the most grease out of the water. If you under size your grease trap, some of the grease could pass through and also you might need to pump out (take the grease out of) the trap quite frequently.

Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.
