Commercial Kitchen Ventilation Systems

Commercial Kitchen Ventilation Systems

In a commercial kitchen a ventilation system is an essential piece of the jigsaw that keeps a commercial kitchen functioning. It might look like just a box where air can enter, but on closer inspection it is a series of parts that when combined, allows efficient ventilation for the kitchen as well as for health of the kitchen staff. Having a safe working environment is essential.

Even though there are more advanced commercial ventilation systems in the modern age, an effective clean canopy system is needed to minimise the amount of grease that can easily build up.

It’s also important for smoke from the kitchen to be removed from the air for health and safety reasons. There is a complex system of working parts which takes the smoke from the kitchen out through an outlet which is positioned on the roof.

Key Parts of a Restaurant Ventilation System

If you have a restaurant, these are the key parts you would need to create a ventilation system:

Certified Fire Suppression in the Kitchen Hood or Nearby

Certified fire suppression systems are legally required for all commercial kitchen ventilation systems. A fire suppression system that passes all testing requirements, should be able to put out an oil fire which burns at over 680 degrees Fahrenheit. Chemicals and water can be used to extinguish this type of fire.

Commercial Kitchen Canopy

Many of the important parts of the ventilation system are contained in the commercial kitchen canopy (also called a kitchen hood). So the commercial kitchen canopy is the main part of the exhaust system which is positioned inside the premises. You will find the canopy usually above the area where cooking takes place. The strategic positioning is to make sure as much smoke and unwanted particles in the air can be taken from the air so it can’t be inhaled.

The Make-up Air Unit – Ensuring Non Contaminated Air

The make-up unit’s job in principle is to replace polluted unhealthy air from the cooking area inside the kitchen with clean air. At their optimum a make-up unit should be able to replace all of the removed exhaust.

Hood Filter Bank Contains the Grease Filter

A grease filter sits inside the hood filter bank and its job is to make sure any unwanted particles or oil get into the actual exhaust system.
Regular cleaning of the filter inside the hood is needed to avoid any excess build up of grease.

Upblast Exhaust Fan Fixed to the Exterior of the Premises

Situated on the exterior of the building is what is called an upblast exhaust fan. This fan is used so to drive the unwanted air out of the ventilation system. There isn’t a problem with any grease spilling out from the ventilation system, because the fan will also filter the grease to avoid grease landing on the roof.

Types of Commercial Kitchen Ventilation Hoods

– You will need a wall canopy hood if your stove and cooking equipment is positioned against a wall. You can consider installing an island hood on the ceiling if there are no walls around. Commercial hoods that are used in kitchens are a necessary requirement when you use cooking surfaces that expel anything grease related.

– In a scenario where the cooking surface produces just condensation and heat and condensation, you will need a different type of hood which doesn’t have a grease filter.

Types of Commercial Kitchen Ventilation System Rooftop Exhaust Fans

Belt Drive Exhaust Fan
Belt drive exhaust fans operate through a motor shaft that is controlled by a belt-and-motor pulley. As the belt vibrates, it creates friction, which can cause a decrease in fan performance and necessitate repairs. They are favored by many restaurant owners for their affordability and quiet operation. A type of upblast exhaust fan.

Direct Drive Exhaust Fan
The fan blades on a direct drive exhaust fan are directly connected to the motor shaft, eliminating the need for a belt. They contain fewer parts than a belt drive fan and have the added bonus of reducing energy usage thanks to more efficient operation. While they are generally higher in price, many people believe that the ease of maintenance and cleaning offsets the higher upfront costs. A type of upblast exhaust fan.

Types of Commercial Hood Filters

  • Spark arrestors: When solid cooking fuels are used for tasks such as grilling (containing substances such as charcoal or hardwood) and sparks can be seen in the air, spark arrestors are required to be used.
  • Hood filter material: Composition of a hood filter is primarily either galvanised steel, stainless steel or aluminium. (i) The less expensive choice would be aluminium which is also very light. (ii) Galvanised steel filters will last longer and are open to corrosion, but will generally cost more than aluminium filters.  For a low maintenance choice, stainless steel filters however are the most expensive out of the three, and they have ant-corrosive properties.

Types of Make-up Air Units

  • Tempered make-up air units: can supply the kitchen with non-contaminated air to replace what has been removed by the ventilation
    system, but tempered units can also heat or cool the air to increase the comfort level of the kitchen environment. A type of make-up air unit.
  • A make-up air unit which isn’t tempered: these are less expensive than the tempered version.  When experiencing extremes of temperature, this type of unit is more suitable.
