1- Type I Hood of a Commercial Kitchen Exhaust Hood Work

experts install these hoods over cooking equipment that produces grease. 

These hoods come with a fire suspension unit because the grease is more prone to catch fire and needs something to suppress it.

Let me give the example of appliances producing high grease and oil dirt. When working with charcoal, BBQ, and stir-fried food, they produce many grease and fumes. 

Type I hoods will have filters to catch all greases and prevent them from entering the exhaust lines. 

2- Type II Hood of a Commercial Kitchen Exhaust Hood Work

These hoods also take the name of oven hoods. Their primary purpose of the use is to remove hot air and steam. 

experts install them over appliances that do not produce fumes and grease but rather just heat. 

These hoods have the ability to create a comfortable atmosphere for people working in the kitchen, as the added heat will make it impossible to work in the kitchen. 

As it is removing heat, it also works by removing any foul odors that can undermine air quality in your commercial kitchen. 

Exhaust Fans in a Commercial Kitchen Exhaust Hood Work

In commercial systems, professionals install the exhaust systems externally. Usually, there are two types of exhaust fans in the market. 

1- Belt Driven Exhaust Fans for a Commercial Kitchen Exhaust Hood Work

A belt driven kitchen exhaust model for proficient air flow.

As the name suggests, the motor exists independent of the fan blades. The connection between the fan parts as well as the motor is one or two belts driving force. 


  • It is cheaper than other alternatives out there. 
  • You have more control over the fan blade’s speed.
  • Makes a lot less noise. 


  • The issue you may face here is that the belt produces friction that can lead to wear as well as tear of the parts of the fan. This wear and tear mean you have to do a more significant deal of maintenance. 
  • Also, this proves to be less energy efficient as a lot of energy is lost in the friction produced by the belt.

  • These fans are pretty expensive. 
  • They may be producing a lot of noise. 

Making-up Air Units 

The exhaust fans are sucking up the air and vent them out of the building. Not replacing the air will be a problem in your kitchen. 

Stainless steel air units for providing clean and fresh air in the house.

Therefore, people install air units. They replace the bad air with new fresh tempered air according to the kitchen requirements to maintain the internal pressure of the kitchen. 

The best type for a commercial kitchen is an evaporation cooling unit.

How do these temper the air? 

  • The fresh air goes inside the ducts that then passes through the cooling pads continuously damped by a water pump. 
  • The air, after being cooled, is forced into the building, making the overall atmosphere of the kitchen pleasant. 

Exhaust Filters

Type I hoods have grease filters, and nowadays. People use baffle filters in most kitchen exhaust hoods. 

They also ease the cleaning process as all the grease collected is stored separately. 

They are the most efficient in trapping the grease by changing their direction as soon as the grease particles hit the filters. Most baffle filters are made up of stainless steel. 

Fire Suppression Unit

These are beneficial to reduce any chances of a fire in your cooking appliances. It is necessary for all type I hoods to come with a fire suppression unit for the safety of a commercial kitchen.

The basic working principle of this part is that specific chemicals start to release whenever there is an increased chance of the grease catching fire.

  • The extinguishing chemical is concealed in a stainless steel box.
  • There are detectors placed in the kitchen hood set at certain heat levels. As the stove’s heat rises above the set parameters, the chemical is released through the nozzles and pipes.
  • Now here, you need to keep in mind that the hood should cover all of the stoves to put out the fire completely. 

Ozone or Ultra-Violet Features

Some commercials exhaust the feature of ozone. The dust particles are large, and while passing through the ducts, they may accumulate, making ventilation difficult.

The ozone that releases into the ducts makes the grease particles smaller so as not to stick up in the ducts.

The benefit of ozone of ultraviolet features is reducing the maintenance as well as the cleaning of the ducts to quite an extent. 

  • It ensures a smooth flow of grease to the outside environment. 
  • It also helps in reducing unwanted odors in the kitchen. 

Maintenance of Your Kitchen Exhaust Hood

Maintenance is the key to working a commercial exhaust hood if you are not cleaning and maintaining the ducts, filters, and fans. 

Make sure it is clean according to its use. Commercial kitchens need their exhaust system cleaned once in three months to ensure a smooth-running exhaust system.

Negligence in the maintenance of your exhaust hood can lead to fire hazards that can put your workers and kitchen at risk. 

Know When to Clean Your Kitchen Hood

It is essential to know when it’s time to clean the kitchen exhaust hood before the situation gets even worse:

  • Unusual odors persist in your kitchen. 
  • Your fan motor is working so hard that it produces more sounds than usual. 

If you observe any atypical signs while working in your kitchen, never neglect them and ensure your exhaust hood is working efficiently. Also, ensure to clean the oily kitchen exhaust fan regularly.

Last Words

To summarize how your kitchen exhaust works: 

  • Grease particles enter the hood by sucking the exhaust fan.
  • The filters fit into the hood and capture the grease and dust particles.
  • The rest of the air flows into the ducts.
  • The Ozone system destroys any kind of large particles and odors.
  • Air is released into the outside environment. 

You need to know the working of your commercial kitchen exhaust in order to make the best decision in terms of the individual parts. 

Finally, if any issue occurs with the ventilation system, you would know the parts with their function, which will make it easy to know the root cause of system failure. 


What is a Ceramic Hob? Should you Install it in your Kitchen?

Are you struggling to build your dream kitchen? A ceramic hob can be the perfect step to build one. But what is a ceramic hob? Don’t worry, I have got it all covered for you.

Teardown of Ceramic Hob

It goes by the name of ceramic hob, but does it mean it is made of ceramic? Not exactly! Instead, the ceramic in the name suggests that it has a ceramic finish.

But what is a ceramic finish? It is a strong material that can bear a lot of weight and will not shatter when heated. It can withstand high temperatures, which is ideal for you to cook meals.

How Does a Ceramic Hob Work?

Ceramic hob looks like a rigid layer of glass laying on top of your countertop, but only with your naked eyes, of course. 

Although there is a glass, underneath you will find the heating system. When you turn on the hob, the heating elements get warm, and that heat transfers to the pan and then to your food.

Why do you need to have a Ceramic Hob?

Let’s guide the elephant in the room; why do you even need to choose a ceramic hob? Here are the following aspects that you should consider before choosing a hob.

1. Easy to clean

The ceramic hob is designed in such a manner that it is convenient to clean it at all times. It is a flat glass that is easy to reach and clean. So, you can tick the kitchen cleaning checklist easily.

They are cheaper with almost the same benefits as an induction hob. Why wouldn’t anyone like an economical option that shall not be so heavy on the pocket?

Induction Hob Vs. Ceramic Hob

When anyone has to choose between two options, they are more likely to stumble upon both of them for a long time. The other option that goes head-to-toe with ceramic hobs is the induction hobs. So here is a better understanding of the differences between the two of them.

Induction hobs use magnetic principles: Induction hobs work only when the pan is in contact with the surface of the hob. It works on the principle of the magnetic field. This results in better control over the heat and, consequently, energy conservation.

Ceramic hobs have heating coils: The heating coils underneath take some time to heat up, which results in poor control over the amount of heat and the exposure time.

What are the Issues of Ceramic Hob?

Every product has its shortcomings, and you should be aware of them before you finalize your purchase.

No Control Over Heating: Unable to control the heat is crucial when it comes to cooking, and in a ceramic hob, you don’t lack heat control that can result in a bad cooking experience.

Not Safe Around Kids: You need to know that as a ceramic hob takes time to heat up, it will also take time to cool down completely. If anyone forgets and places their hand on the hob, they are likely to get hurt.
