How Duct Fume Hoods WorkDuct fume hoods operate like a powerful vacuum cleaner, sucking in harmful fumes and vapors from a source and expelling them out of your workspace. The process starts when the hood is turned on, triggering the fan to create airflow. The fume-laden air is drawn into the hood, where it is mixed with clean air. The combined air is then pushed out through the exhaust vent, creating a negative pressure that keeps the fumes from escaping into the air.
This drafting airflow is crucial for capturing and removing fumes. Understanding how duct fume hoods work will help you identify potential issues and make adjustments to optimize their performance, ensuring a safer and more efficient workspace.
Types of Duct Fume HoodsThere are several types of duct fume hoods, each designed for different applications and environments. The most common types include:
