If you are a newbie or thinking of replacing your old range hood, you might get confused with type 1 and type 2 kitchen hoods. It’s kind of a rocket science thing, but we got you covered.
What is required for a type 2 kitchen hood? Do you really need it? Well, a type 2 kitchen hood is not meant to exhaust the smoke, grease, and fume. It doesn’t even sit on top of the stove, grill, or pizza oven.
So what is it for? The type 2 kitchen hood is made for other huge appliances like the dishwasher, pasta cookers, ovens, and other heat generators. The main job of a type is to keep the air cool around the people working in that department by removing heat and steam.
Let’s look into it in detail which will clear up more about it.
What Is the Basic Requirement for a Type 2 Kitchen Hood?
As Type 2 hoods do mainly air exhaust, it requires a centrifugal blast exhaust fan. Which draws air into it. And it extracts all the hot air, and moisture from the kitchen through a duct and guides it outside. A makeup air fan (commercial) can also aid in the ventilation of the restaurant to make the work of the Type 2 kitchen hood even more easy.
What Is Type 2 Hood Required For?
Commercial kitchens have huge spaces and appliances. This means huge stove tops, broilers, fryers, grills, pizza ovens, and more. Depending on the type of restaurant, the appliances change a bit.
What doesn’t change is the range hood they use. All of the greasy, fume-emitting, and fire-burning appliances like the stove, grills, fryers, and wok stoves have and must have a range hood over them. And that is where the Type 1 kitchen hood comes in. These are responsible for keeping the kitchen grease and smoke-free.
But what about other appliances that generate heat? Like the oven, dishwasher, rice cooker, hot dog grills, and warming ovens? They also generate heat, which is very uncomfortable for the people working in the kitchen.
This is where the Type 2 kitchen hood works its charms. Unlike Type 1 with a filter, Type 2 has a duct collar to exhaust all the hot air, and moisture and keep the cooking atmosphere comfortable. It is also called a Condensate hood or Oven hood.
It not only keeps the hot air and moisture at bay but also lets the air circulate throughout the kitchen from the commercial makeup fans.
Are Type 2 Hoods Really Necessary?
For any good size restaurant that had commercial grade equipment, be it a dine-in, take-out, or bakery, you will need a Type 2 hood. Otherwise, the moisture and heat will make the workers uncomfortable to work. Hence bad outcome.

Conclusion
Type 2 hoods cannot replace Type 1 or neither can the latter. Each of them serves a whole different purpose and is good at it. Do not use them in the wrong place you might cause malfunction or unsuitable outcome. And Type 2 hoods are not to be used at home, just so you know.
