What is Grease Shark

Say Goodbye to Manual Kitchen Extract Cleaning.

Grease Shark is an automated system that uses advanced biotechnology to prevent grease, fats, and oils (FOGS) from accumulating in your commercial kitchen extract system.

Grease Shark will spray environmentally friendly biological enzymes into the extraction and ventilation system and dissolve the grease, fats, and oils. The broken-down particles are then extracted through the extract fan harmlessly into the atmosphere.

The extract system is therefore TR19 & NFPA Code 96 compliant 24/7 by using the Grease Shark system.

Works very well and cuts down maintenance and gets to places of difficulty with ease. Keep up the good work.

“With the Grease Shark system automatically cleaning your canopies and extract on a daily basis, you can finally say goodbye to the conventional canopy cleaning grind.”

With your kitchen operating at full force, grease is certain to build up in your kitchen canopy and extract system. It’s just an unavoidable by-product of cooking. But keeping your kitchen clean is essential to reduce the risk of fire. Safe and efficient operation requires that grease build up is completely and regularly removed. That’s an expensive, time-consuming proposition. Now, there’s a way to make it effortlessly automatic.

Using advanced biological technology, The Grease Shark penetrates every element of a kitchen canopy, extract ducting and extract fan, breaking down grease particles as it goes and putting an end to costly and time-consuming manual scrubbing cleaning. In addition, The Grease Shark removes any residual door which can be a nuisance for neighbours.

How Grease Shark Works

When a kitchen extract system is cleaned manually grease starts to build up again immediately on use.With the Grease Shark system grease is never allowed to sit in the canopy, ducting, so a grease free canopy, duct and fan 24/7.

Grease Shark works by introducing fine micro droplets of enzymes into the kitchen extraction and ventilation systems, ensuring that wherever air flows Grease Shark will follow into ductwork, canopies, filters, fans, silencers and ventilated ceilings.

At an interval determined by the volume and type of cooking taking place, the pump engages and sprays the enzymes throughout the system. The spray apparatus is installed within the canopy itself, behind the filters.

The enzymes break down any grease present, and the residue from this process exits with the air flow and is harmlessly absorbed by nature.


Installation of the Grease Shark system is easy. Pre installation we will know all we need to know from an on-site survey, so we arrive fully prepared for a fast installation.


We will carry out the required TR19 inspections as stipulated by your insurance company and provide the relevant TR19 certification.

When looking for a solution to manage the kitchen’s cleanliness and efficiency, which is always a priority in a busy kitchen. We had a problem with Grease buildup in our extraction systems which was  becoming a persistent headache, and leading to both safety concerns and very costly maintenance.

This led me to the Grease Shark system. I was initially unsure of how effective it was going to be, as it was a new concept product.

Being a busy venue in the city we decided to take the leap and ordered the system.

Once installed, the reduction in grease in our hood was actually so good that I had to check with the porters to find out if they had cleaned it.

Since then, Grease Shark customer care is excellent. They are more likely to contact me than the other way around. And when I do require consumables or anything, they are on-site as soon as possible.

I have, and do recommend Grease Shark. It certainly made a big difference in our systems and undoubtedly will in yours.
