What is the purpose of a Type II kitchen hood?

A Type II kitchen hood is specifically designed to remove steam, vapor, and odors produced during cooking processes that do not generate significant grease. These hoods are commonly used in kitchens that primarily handle food preparation that involves boiling, poaching, steaming, or simmering, which are less likely to produce large amounts of grease-laden vapors compared to other cooking methods.

The functionality of a Type II hood revolves around efficiently ventilating the kitchen environment to maintain air quality by eliminating unpleasant odors and excess moisture. This helps create a more comfortable and hygienic workspace for kitchen staff and is crucial for preventing the build-up of steam, which can lead to slippery surfaces and other hazards in a busy kitchen.

Understanding this function is essential, as it distinguishes Type II hoods from others designed primarily to handle more grease-laden emissions, which is a key consideration for kitchen design and compliance with mechanical code regulations.
