Grease Lock System


Traditional grease filters used in commercial kitchen ventilation systems do not effectively remove greasy particulates from the air before entering the ducts. This results in a rapid build-up of grease throughout the exhaust system and on the roof. The accumulation of grease in the exhaust system is a significant fuel source posing an increased fire risk for restaurant operators.

As a result, the grease filters need frequent, even daily,cleaning. The cleaning process for grease filters uses large quantities of water, chemicals, energy, and labor, and adds significant operational costs to a restaurant. In addition to the frequent cleaning of the grease filters, the operator must routinely inspect his exhaust ducts and extractor. Typically,this results in a costly quarterly hood cleaning service performed by a certified hood cleaning company. The Grease Lock System is a 2nd generation, disposable grease removal device that reduces grease build-up by removing a significant amount of the grease before it enters the exhaust system. This results in fewer cleanings of the baffle grease filters and extends the time between required hood and duct cleanings.

The exhaust system remaining cleaner for longer periods reduces the risk of an exhaust system fire. This sustainable alternative also conserves water and reduces pollution. The Grease Lock System is placed upstream of listed baffle-type grease filters and uses custom channels to hold in place the Grease Lock Filter. The Grease Lock Filter is Intertek/ETL listed and is comprised of a proprietary blend of fibers with an embedded stabilizer frame. The unique,patent-pending design of the Grease Lock System allows for the filters to capture a significant portion of the greasy particulate matter from the cooking effluent with minimal effects on airflow and only a very small increase in static pressure. Exhaust fan upgrades are typically not required. The Grease Lock System reduces the risk of fire and the frequency of messy cleaning processes and maintenance costs, thereby saving you money while protecting your assets.
