Environmental Issues From the Roof Top

The grease produced from commercial kitchen and restaurant cooking areas travels up the ductwork (although a large portion of it is caught in the hood filters), pulled up to the roof by the exhaust fan- the grease then runs into a greasetrap  installed next to the exhaust fan, but a lot of the grease ends up just on the roof. Professional hood cleaners, at each service, will go up to the roof, open the exhaust fan, and clean the fan and the surrounding area, which usually is full of grease.

Until now, hood cleaners have had to direct all of the chemical laden wastewater, as well as the grease, to the gutter. The gutter, of course, is connected to the downspout on the ground, so the gallons of wastewater and pounds of grease, from each and every cleaning at each and every restaurant, empties right onto the ground. As soon as the next rain, that grease and waste will flow either right into the nearest storm drain, or will run directly into a near-by creek, stream or river. Both ways eventually end up polluting our waterways, over and over, as all commercial kitchen and restaurant hood cleanings are required on an on-going basis.

The A1 Gutter Box is an addition to our line of products for cleaning hood filters- it’s a simple system that will have a big impact on this current pollution source from the roofs of restaurants. Hood cleaners now have an option- they don’t have to send the grease waste and chemicals down the gutter to land on the ground. It can all be easily captured and disposed of properly with the A1 Gutter Box. Actually, during any rooftop type work that requires using water, all wastewater is supposed to be captured, not allowed to go down the downspout and onto the ground, same as the requirement for exhaust fan hood cleanings.

When hoods are cleaned professionally, this grease will be directed to the downspout and will empty onto the ground, this waste must be captured before it hits the ground.

Cooking grease next to and on a rooftop exhaust fan of a restaurant. When the hood system is cleaned, this grease gets mixed with the chemical wastewater, then is directed down the downspout, only to empty onto the ground or lot. This waste is required to be captured, we now have a solution for that.

This is our A1 Gutter Box- when we clean rooftop exhaust fans for a restaurant, our Gutter Box is used, it captures the grease and waste that’s directed down the downspout, not allowing ANY of the waste to stay on the ground. It’s pumped back into the kitchen sink where it’s highly filtered through our Sink Filter Box and can be disposed of properly.

This simple design is very effective- connected to the downspout, the catch box here captures all grease and chemical wastewater produced from cleaning restaurant exhaust fan.
