What Are Kitchen Ventilation Systems For Restaurants?
Kitchen ventilation systems for restaurants are air filtration devices that utilize electrostatic filters and supplemental filters such as UV-C to eliminate pollutants such as smoke, oil and odor that form during the cooking process.
The Importance Of Kitchen Ventilation
The most important thing when kitchen ventilation systems are considered is the filtration of the dirty air that is collected in the exhaust hood.
As pollutants such as smoke, odor and oil can’t just be released into the outdoor environment, they need to be filtered.
Otherwise, your business will eventually receive smoke and odor complaints from the neighbors and your local authorities may fine or even shut it down.
Choosing The Right Exhaust Hood
The first piece of equipment that should be determined when building a kitchen ventilation system is the exhaust hood.
When choosing an exhaust hood, factors such as:
Cooking method.
Cooking capacity.
Compatibility with the dimensions of the cooking area.
Compatibility with the fire safety equipment.
should be considered initially.
Air Duct Configuration
The second thing that should be considered are the air duct systems. Factors that should be considered before getting an air duct system are listed below.
– Air ducts should be made in the correct dimensions and types to allow the transportation of pollutant particles from the exhaust hood to the air outlet.
– Air ducts should be made with stainless steel material of 1.09 mm thickness.
– The system should be liquid sealed around the joining points.
– Ductwork shouldn’t have any physical connection with another system.
– There shouldn’t be any areas where oil could accumulate in the ductwork.
– Air duct should be connected with the exhaust fans from the shortest distance possible.
IMPORTANT
Exhaust hood ventilation and indoor air ventilation should be kept separate from each other. Likewise, if your business has both a grill and oven, they should be separated with their own ductwork and air filtration system. Otherwise, air ducts will be smeared with smoke from the grill, and the high heat coming off from the oven will create a fire hazard.
Restaurant Kitchen Ventilation Air Filters
The third component of the kitchen ventilation systems are the filtration products and the exhaust systems. Filtration systems are utilized for getting rid of pollutants such as smoke, oil and odor formed during the cooking process.
Many different criteria should be considered when buying filtration systems. Since the filtration type and capacity will be different for each restaurant, proper designation of the required system should be made by professionals.
Moreover, air filter systems should be chosen target-specific.
– If you have exhaust air polluted with materials such as smoke or oil, electrostatic filters should be considered.
– When odor pollution is present, Activated Carbon Filters or UV-C Light Filters could be considered viable options.
Chimney Systems
Restaurant chimney systems are the fourth component of the kitchen ventilation systems.
Chimney systems are normally where the exhaust air meets outside environment. Filtration systems can be placed both before or after the chimney systems. Using air filters before chimney systems will prevent them from being covered in flammable material such as oil or grease.
Eliminating pollutants are ideal for preventing fire hazards and it’s what Eco-Purge Professional does best. Eco-Purge Smokeless Grilling Units eliminate air pollutants such as smoke, oil and odor at the cooking source and does not require either a chimney system or ductwork.
However, things that should be considered about chimney systems are listed below.
– Ventilation shaft that chimney pipe goes through should be able to withstand fire for at least an hour.
– A chimney covering should be added for ease of cleaning.
– The distance between the chimney and the walls should be designated according to the relevant criteria.
– The gap that chimney pipe goes through the wall should be covered with impermeability in mind.
– The gap air ducts go through floor slabs should be covered with impermeability in mind.
Frequently Asked Questions
Restaurant ventilation systems should be defined under two different specifications.
Indoor air ventilation, which concerns the comfort of the people inside.
Exhaust hood ventilation, which concerns getting rid of the dirty air formed during cooking.
Indoor ventilation refers to systems that aims to keep the comfort levels of the customers and the employees of a restaurant. In such systems, a lot of equipment dedicated to heating, cooling and ventilation can be found.
Exhaust hood ventilation systems aim to filter and dispose of air pollutants such as smoke, oil and odor formed during cooking processes. These systems start with exhaust hoods and include various ventilation equipment like ductwork, filters and chimneys. The main purpose of these systems are preventing kitchens from affecting indoor and outdoor air quality negatively.
In restaurants, a chimney system is required to discharge the exhaust air into the outside environment. Many local authorities require restaurants to have chimney systems in order to be able to get a business license. However, Electrostatic Filtration Systems are accepted as an alternative to chimneys by great numbers of local authorities.
No doubt fires are a great problem for restaurants and the building they’re located at. There are many reasons for such fires and each need to be evaluated on their own to take proper precautions. However, fires caused by exhaust hoods, ductwork and chimney systems being covered in flammable material can be prevented with our products. Eco-Purge Units filter such pollutants and eliminate conditions under which these sort of fires may start.
Exhaust hood filters come in two different installation forms, internal and external. For external configurations, an outer area such as a yard, roof or a terrace is needed. Internal models can be integrated into exhaust hoods directly.
