Product catalog summary
Overview
The document addresses solutions for preventing air leakage and back drafting in ventilation systems, focusing on swine facilities. It emphasizes the use of AP backdraft and Rollseal® dampers, along with Camfil Farr PathogenBarrier filters, to improve air filtration and prevent airborne pathogen transmission, such as the PRRS virus.
Specifications and Features
  • Backdraft Dampers: These are designed to prevent air infiltration through ventilation fans when not operational, made from lightweight aluminum for durability and corrosion resistance.
  • Rollseal Dampers: Suitable for large tunnel ventilation fans, featuring a heavy-duty motor and dual-layer polyethylene fabric for insulation and energy conservation.
  • Camfil Farr PathogenBarrier Filters: These filters are engineered for high airflow and filtration efficiency without relying on electrostatic charge or biocide impregnation, ensuring consistent performance over time.
Research and Testing
Trials by the University of Minnesota demonstrated the effectiveness of PathogenBarrier filters in preventing aerosol transmission of the PRRS virus, showing significant reduction in virus transmission in controlled environments.
Ventilation Systems Design
The document outlines different pressure systems for ventilation:
  • Negative Pressure: Requires sealing the structure to prevent unfiltered air infiltration, using higher filter counts for lower energy costs.
  • Neutral Pressure: Utilizes supply and exhaust fans to maintain pressure, reducing unfiltered air infiltration.
  • Positive Pressure: Offers the greatest protection against air infiltration but requires proper sealing to prevent structural deterioration.
Installation and Maintenance
AP’s filter ducts and banks are designed for easy installation and maintenance, adaptable to various building configurations and ventilation needs, with no tools required.
Conclusion
The document stresses the importance of understanding ventilation design and air pressure to optimize air quality and filtration in swine facilities. It recommends professional evaluation for determining the appropriate filter count and system configuration.
Introduction to Air Filtration Systems
The document discusses air filtration systems in high-value, high-risk facilities like boar studs in Europe and North America, highlighting the adoption of the Camfil Farr L9 PathogenBarrier filter since 2005 due to its lower resistance to airflow compared to traditional HEPA filters.
Impact on Ventilation Systems
The addition of high-efficiency air filters and back draft prevention devices can negatively affect ventilation fan performance, necessitating adjustments such as adding or replacing fans to maintain air exchange rates.
Facility Modifications
Most facilities can be adapted for air filtration with modifications like sealing cracks, removing natural ventilation curtains, adding air locks or double doors, and installing or replacing ventilation fans.
Filter Life Expectancy
The life expectancy of PathogenBarrier filters depends on airflow rate, particulate amount, and environmental exposure. Properly fitted and maintained pre-filters are crucial for extending filter life, typically ranging from three to five years.
Pre-filter Maintenance
The lifespan of pre-filters varies based on environmental conditions and application. They should be changed when visibly dirty or when ventilation performance declines. A scheduled maintenance program is recommended.
Filter Selection
The choice between L9 and L6 PathogenBarrier filters depends on factors like proximity to infected animals, topography, and weather patterns. A risk assessment by a veterinary expert is advised.
Antimicrobial and Electrostatic Filters
Antimicrobial filters offer potential energy efficiency but have concerns about lifespan and effectiveness. Electrostatic filters can increase efficiency without raising pressure drop but lose effectiveness as static charge neutralizes.
Effectiveness of PathogenBarrier Filters
While highly effective in reducing aerosol transmission risk, PathogenBarrier filters cannot completely eliminate it. Proper application, maintenance, and training are essential for effectiveness.

AIR FILTRATION SYSTEMS automated production systems Frequently Asked Questions How does air filtration prevent the spread of PRRS and other viruses? Research has proven that the PRRS virus remains viable in an aerosolized state creating the possibility of a PRRS positive swine facility infecting any other facilities positioned down wind. The use of high efficiency air filters positioned in front of all air entry points into a swine facility simply captures airborne particulate including the virus and its host particle before it can come in contact with the animal population. Is the use of air...
