Industrial Vent Hood System 101: Know Everything Needed For Your Commercial Kitchen

Commercial or industrial hoods are designed to cater to safety as well as functionality for the buildings. If it weren’t for the vent hoods, most of the establishment or building would be enveloped in the remnants of grease vapors that are air-born. If you have a pre-installed system in your commercial building yet you have been experiencing the presence of such remnants, your vent hood might be a faulty one. To avoid any negative health consequences for you or the employees, it is critical that you get in touch with professional service providers for industrial vent hood repair.

Balancing the Needs of a Commercial Space

If yours is a commercial kitchen, an industrial vent hood should be one of the critical components that you install in your vicinity. Your ventilation system functions as a substantial investment for the commercial kitchen, as this is the unit that helps balance the air inside the facility. When the air inside the building is negatively unbalanced, it can create major issues. The total air replacement with fresh air is nil due to the lack of industrial vent hood. This can cause negative pressure in the premise.

This can lead to the dominance of unpleasant odors as well as excessive dirt and dust present inside your building.

How can I know if the ventilation system isn’t working properly?

The best and simplest test to determine the functionality of your system is to opt for the “Front Door Check.” To do this, you need to go outside the premises and open your entry door.

Now, ask yourself three different questions.

  • Is the door easy to open from outside?
  • Does it require a bit of struggle to open the door?
  • Does your door showcase a vacuum-like pressure from the inside?

If the answer to all these questions is a big “Yes,” it is time that you get your system evaluated by a professional. A certified technician for industrial vent hood repair can help ascertain exactly what is wrong with your system. With a reliable service provider, you can avoid issues such as revenue loss, system damage, or health issues that ail the body.

Other known signs of ventilation system error

The door test isn’t the only way to determine any error present in your ventilation system. You can also check for signs such as:

  • Smoke hovering inside the premise
  • A constant need for change in the settings for temperature control
  • Unpleasant odors from outside the building seeping indoors
  • Existence of hot & cold spots in the same area
  • An excessive amount of dust or dirt present inside the room
  • Haze inside the dining room or kitchen
  • Dining room or kitchen is hotter than it is supposed to be

If you are planning to shop for an entirely new industrial vent hood system, you need to make sure that it is correctly fitted & calculated for the space to provide energy efficiency and optimum performance. An incorrectly or improperly fitted system will be nothing more than a massive chunk of highly expensive metal that has been hanging from the ceiling of your commercial space.

Components of the Industrial Vent Hood System

Your commercial vent hood system is comprised of three main components which include:

  • Exhaust Fan
  • Vent Hood
  • Return Air Fan

All these three components need to work in an efficient manner together for optimal functionality.

Frequently Asked Questions about Industrial Vent Hood System

01-What is the CFM needed for my industrial vent hood?

Answer: This is a common myth that the CFM of an industrial vent hood decides how clean your air will be. It sure is critical for your system, but there are other factors that play a critical role as well. Things such as:

  • Types of equipment used for cooking in your premise
  • The type of food being cooked
  • Position of the cooking appliances
  • The positioning of your hood with regards to the appliances
  • The design of the ventilation system behind your walls which include fans, ductwork, as well as air systems

All these factors help determine the CFM you need. So, it will surely vary from one user to another. In such confusing cases, it is critical that you seek help and suggestion from professionals for industrial vent hood repair to get the best system for your commercial kitchen.

02-How does the layout of my commercial kitchen affect the ventilation requirements?

Answer: The way you arrange your kitchen can have a significant impact on the ventilation efficiency provided by your hood. Say, for example, you have placed your ventilation system right above the appliances. This will ensure that the resulting smoke from cooking food goes directly out from the vents without spreading far inside the kitchen. However, having your vent system placed far away from the cooking appliances will make your hood work harder to suck the smoke and push it outside. Within this time frame, the air in the entire area might be affected. So, the layout of your kitchen’s hood system is highly critical to ensure maximum efficiency.

Additionally, you need to make sure that any gaps present in and near the system should be aptly covered. You should mount the hoods as low as possible to ensure maximum efficiency.
