Types of Commercial Exhaust Hoods

A Comprehensive Guide to Commercial Exhaust Hoods

In the fast-paced world of commercial kitchens, one unsung hero stands out - the exhaust hood. These unassuming systems are crucial in maintaining clean air, ensuring employee safety, and mitigating fire hazards, making them indispensable for restaurants and food service providers. Let's embark on a journey into the realm of commercial exhaust hoods, unraveling their types and exploring their ideal applications.

Standard Design Hoods

  • Best Suited For: Standard design hoods are the workhorses of commercial kitchens, excelling at ventilating heat and byproducts like steam and vapor. They are the go-to choice for kitchens where efficient grease removal is paramount.

  • Features: Crafted from seamless steel, standard design hoods effectively capture and contain hazardous particles. While they require routine maintenance, including filter changes and occasional replacements, their enduring popularity is a testament to their consistent performance.

  • Type 1 or Type 2: Ventilation systems that are a bit more specialized will usually fall under two common classifications: Type 1 and Type 2. The primary distinction lies in the substances they are designed to handle. Type 1 hoods are engineered to manage grease-laden vapors, typical in cooking processes involving grilling, frying, or sautéing. These hoods possess specialized grease filters and are equipped to handle the heavy-duty work of capturing and safely evacuating grease-laden particles. On the other hand, Type 2 hoods are tailored for operations that produce only heat and non-grease byproducts, such as baking or boiling. They lack the intensive grease filtration systems of Type 1 hoods, as they don't deal with the same level of grease-laden contaminants. Knowing the difference between these two hood types is essential for making the right choice, and ensuring that your kitchen is both safe and compliant with local regulations.

Ventless Hoods

  • Best Suited For: Ventless hoods are the solution when external ventilation is unfeasible. They shine in scenarios where efficient indoor air purification is imperative.

  • Features: These hoods complete the ventilation process internally, employing a sophisticated three-filter system. The first two filters trap grease and ash, while the third filter screens out smoke and smaller particles. An electric fan circulates gases through these filters, providing an efficient means of kitchen ventilation.

Exhaust-Only Hoods

  • Best Suited For: Exhaust-only hoods are typically used when transported gases are not hazardous. They can safely ventilate areas where harmful particles are not a concern.

  • Features: As the name suggests, exhaust-only hoods are a straightforward approach to ventilation. They use fans to expel contaminated air to an external location. However, unlike standard design and ventless hoods, exhaust-only hoods lack filters to capture grease and other particles.


In the diverse world of commercial kitchens, selecting the right exhaust hood is not a one-size-fits-all decision. Your choice depends on the nature of your cooking operations and the specific needs of your kitchen. When considering your options, you must recognize that each hood type serves a unique purpose, ensuring your kitchen runs smoothly and safely.
