A commercial kitchen duct takes noxious smoke, cooking exhaust and other contaminants from the kitchen, vents them outside, and helps keep your business clean and safe. The duct also plays an important role in the prevention of fires, which is why proper kitchen ventilation is so important.
A properly designed kitchen exhaust system is a vital component of a restaurant, but there are several different ventilation options available depending on your space and needs. Whether you need a vent hood that can be vented directly to the exterior or one that doesn’t require external ducting, we have a kitchen ventilation solution for your business.
Duct Size and Location
For the best airflow, choose ducting that is the same or slightly larger than your vent opening. Use a smooth interior metal duct and seal all joints with mastic tape to ensure good air flow. If you need to install your duct in a tight space, try to minimize the number of elbows; each one adds resistance and decreases airflow. Try to include at least 18’ of straight duct before adding an elbow.
Duct Accessibility
Grease and other contaminants accumulate on the inside of your kitchen exhaust duct over time, so it’s crucial to make sure that you have sufficient access points for regular cleaning and inspection. Local codes and grease accumulation will determine how often your ducts need to be cleaned, but it’s recommended that you have access panels every 12’ of vertical ducting.
