Types of Commercial Kitchen Hoods

Selecting the appropriate commercial vent hood for your kitchen is vital to upholding air quality, regulating room temperature, and averting fire risks. Determining the suitable hood for your restaurant relies on your kitchen equipment and adherence to local commercial kitchen hood codes.

Learn about different types of commercial kitchen hoods and commercial range hood systems typically used in commercial settings in this article below.

What is a Commercial Kitchen Hood?

The commercial kitchen hood is the hub of the interior exhaust system. It consists of many other important components of the ventilation mechanism. It sits directly above the cooking area, to catch as much smoke, cooking heat, odor, and debris as possible.

Importance of Kitchen Hoods in Commercial Kitchens 

In an environment of constant use of a stove, while cooking in a commercial kitchen, it’s necessary to count on an effective commercial kitchen hood system to keep the commercial kitchen environment safe and clean. It is also essential to protect expensive equipment from damaging grease build-up.

Finding the right commercial kitchen exhaust hood for your kitchen is crucial for maintaining air quality, keeping the temperature at a comfortable level, and preventing fire hazards.  The foremost step in any commercial kitchen hood installation is to understand what type of hood is required.

The hood type needed is based on the usage. Kitchen hood specifications also depend on the type of cooking equipment that will be installed under the hood. Commercial kitchen exhaust hoods serve very different purposes. For example;

  • A Hood that can remove moist warm air from a dishwasher or steam table does not necessarily remove grease from the exhausted air.
  • A hood installed over a deep fryer or a kitchen grill does need to be capable of removing grease.

This guide will go over the commercial kitchen hood type 1 vs type 2 and various commercial kitchen range hood systems that are found in a commercial setting to ensure you are outfitting your kitchen with the correct ventilation.

Commercial Kitchen Hood Type 1 Vs Type 2

Types of Commercial Kitchen Hoods

Commercial hoods are divided into two types based on whether or not they are designed to handle grease. Find details about types of kitchen hood systems below;

Type 1 Range Hoods (Grease hoods)

Type 1 range hoods are required to be installed above all commercial-type deep fat fryers, fry grills broilers, steam jacketed kettles, ovens, BBQ, rotisseries, hot top ranges, or other grease or smoke-producing equipment.

A wall canopy hood can be installed if the cooking equipment is located right against the wall. In cases where no walls are present around the stovetop then single or double-island hoods can be installed on the ceiling.

  • A make-up air (MUA) device is installed in type 1 range hoods to ensure that enough fresh air is entering the building to replace or  “make up for”  the contaminated air that is being exhausted.
  • Include grease filters or baffles to catch and remove grease.
  • It is Custom-built according to the operator’s requirements and specifications. This ensures that every piece of equipment that will be placed under the hood is properly covered.
  • Type 1 range hoods must be regularly cleaned to prevent grease buildup that can cause grease fires.

Type 2 Hoods (Condensate hoods)

Type 2 hoods are installed to be used for such washers, steam tables, and ovens that emit heat, condensation, and steam.

  • Not designed to use over grease-producing equipment as they lack a grease filter.
  • Help remove excess heat from the air, creating a more comfortable environment for the individuals working close to the area.
  • Some models are designed to remove condensation and steam only while other models are designed to remove heat and odors.

8 Common Styles of Commercial Kitchen Hoods

Types of Commercial Kitchen Hoods

Various styles of kitchen hood systems are available in the market. Your choice of a range hood should depend upon your type of kitchen, your kitchen size, the layout of your kitchen, the location of your cooktop, your cooking preferences, and your budget.

Undercabinet Hoods

Undercabinet, range hoods are installed under the bottom of a kitchen wall cabinet above the cooktop. Undercabinet hoods come in many styles and strengths. They can be ducted or non-ducted. Cost-effective and easy to install, the canopy or undercabinet range hoods send smoke and fumes out of the wall or up through the ceiling. Some models recirculate the air, so this makes them easier and less expensive to install.

Wall-Mounted 

These hoods are similar to undercabinet hoods but the difference is that they mount to the wall instead of the cabinets above. These hoods are an option when there are no cabinets over the range.

Chimney Range Hoods 

The chimney range hood consists of a range hood over a stove, with a vertical flue, or chimney, that rises from the top of the hood. The chimney continues to run through the kitchen ceiling, attic, and out of the roof.  If you have cabinets fixed above the range, you’ll need to remove them to install this type of hood to fit and function properly.

Chimney range hoods can be located anywhere in the kitchen. They can be installed even in the middle of the kitchen over an island. Chimney hoods contribute to the overall look of the kitchen and can make a style statement.

Island Hoods

A ductless island range hood attaches to the ceiling. It collects the smoke, filters the air, and pushes it back into the room. That air is much cleaner than it was before. This is often the preferred option for easy installation. Island hoods should be wider than the cooking surface as they lack a wall or cabinets alongside them to help funnel fumes.

Downdraft Hoods

A downdraft hood is hidden in the cooktop and pops up when in use. These hoods are designed to eliminate the need for an overhead vent. These systems help capture rising smoke, fumes,  steam, grease, and odors at the cooking surface. It then exhausts them through ducts running beneath the floor and out of the kitchen before they can escape into the air. Although they can be used anywhere in the kitchen, they are typically installed in islands where it might not be possible to route ductwork through the ceiling.

Range Hood Inserts

Power packs or inserts are hoods that are hidden. They’re built into the cabinet above the cooktop for a custom approach to venting. There are many options available for inserts. It is recommended to so speak to an HVAC contractor who is professional in installing various types of range hoods. They can help you determine which one would work best with your cabinets.

Pro Hoods

Pro hoods are similar in appearance to undercabinet hoods but are larger, more professional-looking, and more powerful than a typical undercabinet model. These are specifically for people who cook a lot and prefer a bigger-looking hood. They can be ducted or nonducted and come in various styles to cater to the exhaust choices of customers. 

Ductless Hoods

A ductless range hood is a ventilation system that does not require ductwork to be installed in your home. This type of installation sucks the steam, odors, heat, and smoke from the cooktop filters it, and returns it to the room instead of removing them completely. The hood filters trap oil and grease droplets dispersed into the air above the range. Some models include an optional carbon filter to reduce odors.

Common FAQs About Types of Commercial Kitchen Hoods

What is the difference between Type 1 and Type 2 commercial hoods?

Type 1 hoods are meant for removing grease, smoke, heat, and steam generated during the cooking process. Type 2 hoods are primarily used for capturing heat, steam, and odors produced by non-grease-producing kitchen equipment like ovens and dishwashers.

What type of hood do I need for a commercial kitchen?

Select a Type 1 hood for a commercial kitchen if your equipment produces grease-laden vapors (e.g., fryers, griddles). For heat, steam, and non-grease emissions (e.g., ovens, dishwashers), a Type 2 hood suffices. Compliance with local codes and equipment type determines the appropriate hood for optimal ventilation and safety.

Which type of vent system is used mostly for commercial kitchens?

Type 1 vent systems are predominantly used in commercial kitchens. These systems are designed to handle grease-laden vapors produced by cooking equipment such as fryers, griddles, and ranges. Type 1 vent hoods are essential for maintaining air quality, managing heat, and preventing fire hazards in commercial kitchen settings.
