Types of HEPA Filter Boxes
Inline Filter Boxes
Inline filter boxes are designed to be integrated into existing ductwork. They provide effective filtration for air entering HVAC systems, ensuring that the air delivered to indoor spaces is clean and free from contaminants. Models are available in various sizes to accommodate different duct diameters, including popular options like 6, 8, 10, and 12 inches.
These boxes typically include a pre-filter to extend the life of the HEPA filter, which can be beneficial in reducing operational costs. Brands like HVACQuick offer high-efficiency inline filter boxes that optimize air filtration with minimal pressure drop.
V-Bank Filter Boxes
V-bank filter boxes are designed for larger applications where high air volume needs to be filtered efficiently. They feature multiple filters arranged in a V-shape, allowing for increased surface area and lower resistance to airflow. This design is particularly useful in commercial HVAC systems.
Manufacturers like AAF International provide V-bank filter boxes that are ideal for environments requiring stringent air quality standards. These filters typically come with MERV-13 ratings, ensuring effective particle capture.
HEPA Filter Boxes
HEPA filter boxes are specialized enclosures designed specifically for housing HEPA filters. They are essential in environments where air quality is paramount, such as cleanrooms, laboratories, and hospitals. These filter boxes are engineered to provide low initial pressure drop, enhancing airflow while maintaining high filtration efficiency.
The HVACQuick CFB-HP series offers a range of HEPA filter boxes that fit various duct sizes and include features like quick access panels for easy filter replacement.
Cleanroom Box Filters
Cleanroom box filters are designed for use in controlled environments, ensuring that airborne contaminants are effectively removed. These filters meet the highest standards of filtration, including HEPA and ULPA classifications, making them suitable for industries such as pharmaceuticals and electronics manufacturing.
Companies like MANN+HUMMEL specialize in cleanroom box filters that are customizable to fit specific requirements, enhancing operational efficiency while maintaining compliance with industry standards.
