KITCHEN EXHAUST DUCT

The typical kitchen exhaust system includes three components:

1. Kitchen Exhaust Hood

Kitchen Exhaust Hood is the most obvious and noticeable part of the kitchen exhaust system. The hood is located directly above the cooking equipment, hanging over the stove or fryer and above the cook’s head. The hood collects all the heat and incoming grease vapors being produced from the cooking equipment. Inside the hood, baffle-filters collect and filter the grease vapors before they enter the ductwork. This makes it so less grease finds its way into the ductwork and thus gets expelled into the air outside the building.

2. Kitchen Exhaust Duct

Kitchen Exhaust Duct is connected with ventilation hood all the way up to the exhaust fan on the exterior of the building, most often on the roof. The layout of the kitchen exhaust duct depends on the building design. Some kitchen exhaust systems will have ductwork with only one vertical section that leads directly to the roof while other systems will have varying degrees of horizontal and vertical sections that twist and turn through several levels to get to the exterior exhaust fan. It is these more complex systems that we see a wide array of custom designs fit specifically for that facility. These systems are also the most challenging to clean and require specialized processes and cleaning solutions to properly degrease.at and incoming grease vapors being produced from the cooking equipment. Inside the hood, baffle-filters collect and filter the grease vapors before they enter the ductwork. This makes it so less grease finds its way into the ductwork and thus gets expelled into the air outside the building.

3. Kitchen Exhaust Fan

The Exhaust Fan pulls the air out of the kitchen, through the ductwork and into the air outside the building. Exhaust fans come in various makes and models but all function to remove grease vapor and exhaust from the surfaces of the cooking equipment. The exhaust fan is usually found on the rooftop of the building but can also be placed on the side of a wall or inside a Pollution Control Unit (PSU). A PCU pulls even more grease and sometimes odor out of the exhaust air. PCU’s are generally found in city centers or metropolitan areas where the exhaust could potentially come into contact with nearby people passing by the building.
