7 Reasons Why V-Bank Transition Systems Are Advantageous for Gas Phase Filtration

Gas phase filtration is essential for removing gaseous pollutants, odors, and harmful airborne chemicals from the atmosphere. Unlike traditional particulate filtration that targets solid particles, gas phase filtration focuses on adsorbing and neutralizing volatile organic compounds (VOCs), noxious fumes, and other volatile substances. This type of filtration usually involves the use of activated carbon or other adsorbent materials that possess a high surface area, enabling them to trap and retain gas molecules effectively. A variety of equipment options are available to perform gas phase filtration. One of the most innovative options is PureAir Filtration’s V-Bank Transition System (VTS) system.

V-Bank Transition System Design

The self-contained V-Bank Transition System (VTS) system has a horizontal footprint for spaces with limited height, but high odorous airflow. This system has a deep bed that provides continuous high efficiency air purification for contaminated air streams while maintaining a compact, versatile design.

VTS Advantages in Gas Phase Filtration Applications

Efficient design and unique benefits make the V-Bank Transition System advantageous for high airflow applications in gas-phase filtration. Especially those that involve large volumes of air contaminated with gaseous pollutants.

The following are seven key features that make the V-bank transition system particularly well-suited for gas phase filtration:

  1. High Filter Surface Area
  2. The VTS features a vertical, v-shaped configuration of filter media, providing significantly more filter surface area than traditional flat-panel filters. Larger surface area allows for better contact between the contaminated air and the filtration media, enhancing the system’s gas-phase filtration capacity.

  3. Uniform Air Distribution
  4. The design of the V-Bank Transition System helps ensure more even air distribution across the filters. In gas-phase filtration, uniform airflow is necessary for maximizing the removal of all contaminated air that comes into contact with the chemisorbant media.

  5. Lower Pressure Drop
  6. High airflow applications often result in increased pressure drop across the filtration system. The VTS is engineered to minimize this pressure drop by reducing turbulence and optimizing airflow. A lower pressure drop means less energy is required to move the air through the system, resulting in energy savings and consistent airflow rates.

  7. Longer Filter Life
  8. The high-quality gas-phase filtration media used by the V-Bank Transition System is designed to capture and adsorb gaseous pollutants effectively. The larger surface area and efficient airflow distribution means longer filter life between replacements, thereby reducing maintenance costs and downtime.

  9. Easy Maintenance
  10. The V-Bank Transition System is designed for accessibility, making replacement or service of the gas-phase filters easier. Easy maintenance is essential, particularly in high airflow gas-phase filtration systems that may be installed in industrial environments or critical applications where uninterrupted operation is vital.

  11. Suitable for Various Gas-Phase Media
  12. VTS systems can accommodate various types of gas-phase filtration media, such as activated carbon, activated alumina, or other specialized media designed for specific gas removal applications. This versatility allows the system to be tailored to meet the application needs of different environments.

  13. Space Efficiency
  14. The design of the VTS allows for a higher filtration capacity within a relatively compact housing. This space-saving advantage is crucial in many high airflow gas-phase filtration applications, where available space may be limited.
