What is the Difference Between Type 1 vs. Type 2 Hoods?

Discover the difference between Type 1 and Type 2 commercial kitchen exhaust hoods from the experts at NAKS, Inc..

The Different Types of Kitchen Hoods and Their Uses

When it comes to maintaining a safe and clean professional kitchen environment, proper ventilation is essential. Kitchen hoods play a crucial role in removing smoke, odors, grease-laden vapors, and other airborne contaminants, ensuring a comfortable and healthy workspace. NAKS, Inc. specializes in providing high-quality commercial kitchen hoods, including Type 1 and Type 2 hoods. In this article, we’ll explore the differences between these two types and their specific uses.

Type 1 Hoods

Type 1 hoods, also known as grease hoods or canopy hoods, are primarily designed for kitchens where cooking appliances produce grease-laden vapors and smoke. These hoods are specifically tailored to capture and eliminate airborne grease-laden vapors generated during the cooking process. Type 1 hoods are typically used over equipment like griddles, deep fryers, ranges, and charbroilers.

Key features of Type 1 hoods:

  • Grease Filters: Type 1 hoods are equipped with specialized grease filters that capture grease-laden vapor particles and prevent them from entering the exhaust system. These filters require regular cleaning to ensure their effectiveness.
  • Make-up Air Supply: Type 1 hoods often include a make-up air supply system, which ensures proper air balance by replacing the air being exhausted. This helps maintain a comfortable and efficient kitchen environment.
  • Fire Suppression System Integration: Due to the high fire risk associated with grease-laden environments, Type 1 hoods are commonly integrated with fire suppression systems. These systems detect and extinguish grease fires, providing an added layer of safety.

Type 2 Hoods

Type 2 hoods, also referred to as condensate steam hoods or heat hoods, are primarily used in kitchens where cooking appliances produce heat, steam, and moisture, rather than grease. These hoods are designed to remove heat, steam, and odors from the kitchen environment effectively. Type 2 hoods are typically used over equipment like steamers, ovens, dishwashers, and coffee machines.

Key features of Type 2 hoods:

  • Steam Removal: Type 2 hoods are specifically designed to capture and remove steam and heat generated by cooking equipment. They employ a combination of exhaust fans and ductwork to effectively ventilate the kitchen.
  • Air Circulation: Efficient air circulation within the kitchen is vital for maintaining a comfortable and productive workspace. Type 2 hoods often include an air recirculation system that helps distribute the treated air back into the kitchen.
  • Grease Filtration (Optional): While Type 2 hoods primarily focus on removing steam and heat. However, it’s important to note that Type 2 hoods are not designed to capture heavy grease-laden vapors like Type 1 hoods.


By understanding the key differences between Type 1 and Type 2 hoods, you can make an informed decision based on your specific kitchen requirements. Whether you need to control grease, smoke, or steam, NAKS, Inc. offers a wide range of high-quality hoods to suit your needs.

Remember, proper installation, routine maintenance, and compliance with local regulations are essential for the effective and safe operation of kitchen hoods.
