Omni Containment Systems cannot overstate the importance of having a rooftop grease containment system. It protects your business from a variety of expensive, time-consuming, and dangerous rooftop hazards. When you have an adequate grease containment system installed, it will protect your business more efficiently than if you used the standard grease catch. Once you understand the extreme importance of preventing grease from building up on your rooftop, you might question how to decide which system is right for your commercial cooking facility.

Rooftop grease containment systems come in a variety of styles to suit different needs. The level of grease containment you need depends on factors like the type of cooking fuel used and the volume of cooking your kitchen does. Because no rooftop is the same, we have five grease containment systems that can be fitted to a facility’s unique rooftop situation. Professionals have the option to equip fans with our “Off the Rooftop” solutions that are NFPA 96 compliant.

Here is how you choose the best grease containment system for your application:

  1. Level of Cooking Fuel and the Volume of Cooking

The amount of cooking that is done in the kitchen and the level of grease that is produced will dictate the type of grease containment system that you need. Also, the amount of grease that is dispersed from the kitchen exhaust fan will need to be considered. This could require only needing one side or all four sides of the fan covered. For one-sided configurations, the Grease Gutter Sidekick, Grease Box Jr., and Exhaust Fan Interceptor can be utilized. All of our grease containment products can be found here.

  1. Type of Kitchen Exhaust Fan

Not all rooftops are the same and neither are the kitchen exhaust fans that are situated on top of them. The most common types are the Upblast Kitchen Exhaust Fan and an Industrial Set Type Fan. Both perform essential functions for the entire kitchen exhaust system. If these fans shut down, the kitchen exhaust system will not function. It pays to care for your rooftop kitchen exhaust fan units. All of Omni Containment Systems’ patented grease containment systems can be used on the Upblast Kitchen Exhaust Fan.  Industrial Exhaust Fans are much larger, and the versatility of the Roof Guardian is recommended due to their low clearance.

  1. Clearance

The next consideration that must be factored in is how the kitchen exhaust fan is placed on the rooftop. Pipes and ducts can make clearance an issue for installing a grease containment system. The High-Capacity Grease Gutter was specifically engineered for tight installation situations. If the kitchen exhaust fan has a low clearance or is situated close to the edge of the roof or other equipment, it is only four inches wide and uses a single, easy-to-replace filter. If you do not have at least 6 inches of clearance, then a single-sided grease containment system would need to be considered.

  1. Location

Ideally, the kitchen exhaust fan will be placed on a flat rooftop that is situated right in the middle. Unfortunately, the reality is that kitchen exhaust fans can be found on slanted rooftops or even side-mounted on the building. Omni Containment Systems has several patented grease containment systems that can adapt to each of these scenarios. The Roof Guardian is the most versatile grease containment system. It can be customized for most rooftop situations including a side-mount installation. The High-Capacity Grease Gutter can also be customized for most rooftop situations.
