Grease Containment Systems




Grease Trap specializes is grease containment for the roof of thousands of restaurants utilizing our custom manufactured filter systems.
Our custom manufactured Grease Trap Filter allows water (rainwater and dirty-greasy water from vent hood cleaners) to flow through our custom manufactured filter, while encapsulating the grease from the exhaust fan.
Simply put, the Grease Trap Filter catches the grease while allowing water to pass through it, preventing new grease deposits from ever hitting the roof.
Once the system has been installed, the Grease Trap Filter needs to be changed during regular scheduled hood cleanings.

Our Grease Trap System is easily installed (less than 10 minutes). In addition, we currently provide substantial techn support that includes one-on-one problem solving phone calls and excellent web installation photos and instructions.








Grease Trap was designed by hood cleaners, for hood cleaners, and tested in real on-site environments for over 5 years. Grease Trap uses a natural ingredient as part of our filter system. This process produces a super-absorbent filtering product that resists water-based re-hydration, but absorbs and encapsulates oil and other hydrocarbons. What you end up with is a 100% organic, non-leeching filter that locks in grease and oil, and lets water pass right though. The Grease Trap Filter brings you the safest, non-leeching, proven method for absorbing oil and grease anywhere.



It works, more affordable, and it’s guaranteed. Our systems are more effective than any other competitor on the market. Because we custom manufacture our products we are also able to make our systems more affordable than other companies. In addition, we guarantee our customers (restaurants and hood cleaners) 100% satisfaction.


Depending on a multitude of factors, Grease Trap has many different solutions to the problems caused by exhaust fan grease.

In addition, we offer a inexpensive “GET AQUAINTED KIT” built for hood cleaners. Please review the various Grease Trap PRODUCTS below.

Listed below, you will find descriptions and pictures in order of the most commonly used approaches by Grease Trap and hood cleaners.


Grease Trap Pail System (Medium & High Volume Fan)
The Grease Trap Pail System is our most commonly used solution for grease containment. The Pail System adapts to the grease drain found on the many different styles of exhaust fans. You can view it’s various adaptations.

On average, the pail needs to be replaced during regular hood cleanings depending on the volume of the restaurant. The original adapters and hose stay, while the new pail is connected taking less than a minute to re-install. It is very easy and clean to take the pail off/on the roof making it the preferred system for hood cleaners.

The Grease Trap Pail System has the custom manufactured filter medium inside the pail. The pail has 16 drain holes allowing water to pass through it at a high volume. During cleanings, hood cleaners are encouraged to keep the Grease Trap Pail connected to the drain and “wash the dirty water and grease through the old filter while cleaning” and before installing a new filter, which helps prevent a dirty mess and EPA violations.







Grease Trap Rack System (Medium & High Volume Fan)

The Grease Trap Rack System is our second most commonly used containment system due to it’s versatility and adaptability. The Rack System adapts to the grease drain found on the many different styles of exhaust fans. You can view it’s various adaptations.

The Grease Trap Rack System has the custom manufactured filter (aka “pillow”) inside the rack. The rack has a built in drain that allows water to pass through the system at a high volume. During cleanings, hood cleaners are encouraged to keep the old filter in the rack system in place while “washing the dirty water and grease through the old filter” while cleaning and before installing a new filter, which helps prevent a dirty mess and EPA violations.

During installation only, the Rack System is usually screwed into the vent or curb under the drain spout for the exhaust fan. After the initial installation of the rack, only the pillow (filter) needs to be replaced during regular scheduled hood cleanings depending on the volume of the restaurant. The pillows are inexpensive making this option one to consider for your restaurants.

The replacement pillow is packaged in a plastic sack. Grease Trap recommends placing the old filter in the plastic sack to make the replacement as clean and easy as possible.

For extreme volume fans, Grease Trap has custom manufactured the “Double Deep Rack System” which has twice the absorption capacity as the original Grease Trap Rack System. Customers are encouraged to purchase the original Rack System first. If the volume of the grease exceeds the original Rack System, Grease Trap will send you a “Double Deep Rack System.


Grease Trap Econo 360 Perimeter System

(Down Blast Fan and Leaking Gaskets/Seals)

The Grease Trap Econo 360 Perimeter System provides an excellent and affordable solution to down blast fans and those fans that need grease containment completely around (360 degrees) the fan.

Down blast fans do not have a drain spout and some fans leak grease through gaskets and improper fittings. As a result, some fans have grease leakage on all four sides of the fan. The Econo 360 Perimeter has four rails that easily screws into the vent or curb on all four sides. (Grease Trap also offers a 360 Roof Perimeter System which actually sits on the roof and provides more containment than the Econo 360 Perimeter. You can see it’s installation instructions at install.php

The Grease Trap Econo 360 Perimeter has the custom manufactured filter (aka “boom sock or snake”) inside the four rails that make up the perimeter. After the initial installation of the Econo 360 Perimeter, only the boom sock (filter) needs to be replaced during regular scheduled cleanings depending on the volume of the restaurant. The boom socks are easily disposed of and provide an inexpensive solution to fans with grease leakage on all sides of the fan.


Grease Trap LV Box System

(Low Volume Fan e.g. Fry Fan)

The Grease Trap LV Box System is designed for fans that do not create a significant amount of grease, but still need grease containment.

The LV Box System screws into the vent or curb under grease drain found on the many different styles of exhaust fans.

The Grease Trap LV Box System has the custom manufactured filter (aka “small pillow”) inside the box. The box is not completely sealed on the corners which acts as a drainage system allowing water to pass through the system at a high volume. During cleanings, hood cleaners are encouraged to keep the small filter or pillow in the LV Box in place while “washing the dirty water and grease through the filter while cleaning” and before installing a new pillow, which helps prevent a dirty mess and EPA violations.

After the initial installation of the LV Box, only the small pillow (filter) needs to be replaced depending on the volume of grease created by that fan.

The pillows are inexpensive making this option one to consider for your restaurants. The replacement small pillow is packaged in a plastic sack. Grease Trap recommends placing the old pillow in the plastic sack to make the replacement as clean and easy as possible.
