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:
1. Wall Hoods: These portable, manual devices are perfect for small industrial settings like machine shops or workshops. Wall hoods are ideal for controlling fumes from specific areas and are easy to move around as needed.
2. Canopy Hoods: Larger and semi-automated, canopy hoods cover a work area, such as a bench or table. They are commonly used in laboratories, food processing facilities, and printing shops. These hoods are equipped with sensors and automatic controls to maintain consistent airflow and provide efficient fume removal.
3. Fume Cabinets: These are large, enclosed units designed for high-capacity fume removal. Fume cabinets are ideal for use in industrial plants, chemical facilities, and manufacturing plants where large volumes of fumes are generated. They offer comprehensive protection and high airflow capacity.
Each type of duct fume hood has its own advantages and limitations, and the choice depends on the specific requirements of your application, such as the size of the fume source, the desired airflow rate, and the available space.
Factors to Consider When Purchasing Duct Fume HoodsWhen selecting a duct fume hood, its important to evaluate several key factors to ensure the hood meets your needs and performs efficiently. These factors include:
1. Velocity: The airflow speed of the hood is measured in feet per minute (FPM) and determines how quickly the hood can remove fumes from the workspace. Higher velocities are generally better, but it depends on the size of the fume source and the desired exhaust pressure.
2. Airflow Capacity: The maximum volume of air the hood can move per hour is measured in cubic feet per hour (CFH). Ensure the hood has sufficient airflow capacity to handle the fumes generated in your application.
3. Capture Radius: The distance from the hood where fumes can still be effectively captured. A larger capture radius is better for preventing fumes from escaping, but it may require a larger hood.
4. Material Resistance: Duct fume hoods are made of various materials, such as metal, plastic, or composite materials. Choose a material that can withstand the chemical, physical, and thermal challenges of your fumes, such as resistance to oils, acids, high temperatures, and particulates.
