• Advanced Air Filters for Healthy and Sustainable Indoor Environment
  Dr. Christine Sun, Freudenberg Filtration Technologies, L.P.
  

  [ Open Abstract ]

  Air filtration is a necessity of modern HVAC systems to maintain indoor air quality and has advanced rapidly in recent years in performance, especially to clean airborne contaminates such as fine dust, smog, pollens, bacteria, virus, etc. Though there are several standards established to measure particulate filtration efficiency, none exist currently to classify filter energy efficiency. In this research, lab and field studies were performed on modern air filters using ASHRAE Standard 52.2-2007 for fractional filtration efficiency and a recently developed method (wattage) for energy efficiency classification. Further life-cycle cost analysis of air filters will be demonstrated based on a real case to promote clean, healthy, and sustainable air filtration technology.

• Gas Turbine Intake Air Filtration: Proper Selection and Optimization
  Monroe Britt, Green Leaf Technologies, LLC

  [ Open Abstract ]

  All too often, the performances of gas turbines are adversely affected by improper selection of air filter medias used in the various stages of intake air filtration. The operating environments of gas turbine filters are significantly more severe than for HVAC filters. With the present major emphasis on maximum power output with minimum inlet air flow resistance , all stages of air filtration must be properly selected for the local site conditions, including inlet weather protection. Use of higher efficiency filters, such as HEPA, is gaining in acceptance even though the intake air filtration resistance is higher. Cleaner compressor stages provide better performance with less down time for maintenance. Also optimization of air filter final resistance and operating costs should be evaluated to determine the actual useful service life of air filters. Careful recording of air filter performances and gas turbine power output throughout the year will provide extremely important data for overall cost evaluation and optimization.

• The Economics of Integrating Nanofibers into a Product and an Example of the Benefits to an End User of Retail Filtration Products
  Kenneth Donahue, Elmarco, Inc.

  [ Open Abstract ]

  The benefits of nanofibers have long been understood in regards to increased filtration efficiency with a lower penalty for pressure drop than other methods. Based on cost models using commercially available electrospinning equipment and confirmed by filter producers using the equipment in the field, we will lay out the economics and key inputs into determining the costs of integrating a nanofiber layer into a filter. Further, we will lay out customer reported data on the savings experienced by end users using filters with a nanofiber layer product in a commercial environment.

• Business Process Engineering
  Kanwar Suri, PTI Technologies Inc.

  [ Open Abstract ]

  Business process engineering or techniques are recognized worldwide as a highly profitable means to achieve increased profits, client satisfaction, and improved quality. It is the radical application of scientific principles and analytical techniques to product or service delivery processes, systems of work, management systems and organizational structures and beliefs to achieve dramatic enterprise performance improvements. What many come to realize is that creativity is more than the ability to come up with a clever design solution or a smart idea. They learn to see creativity as a formative ability with real impact on productivity and results.

Lunch (On Your Own)

Molecular Contaminant Filtration (Gas Phase)

2:00 p.m. – 4:00 p.m.
Moderator: Jay Forcucci, Filtrair, Inc.

Gain a complete understanding of your gas phase system (from contaminants to construction) to get as much performance as possible! We’ll look at gas phase filter performance from the mechanics of carbon (and other functional particles) loaded filters to their construction, application and efficiency testing. With a better understanding of gas phase filter systems, you will be able to reduce your costs without sacrificing performance.

• Basic Introduction to Gas Phase Filtration
  Jay Forcucci, Filtrair
• Bulk Carbons
  Paula Levasseur, Cameron Great Lakes, Inc.

  [ Open Abstract ]

  The presentation will provide some general information on the various types of activated carbon and the sources from which they are produced. It will explain how the various sources provide different properties that make certain activated carbons more suited toward an application. A brief definition of the properties and how that information is useful in choosing a suitable carbon.

• Pleated Filters for Removal of Gas-Phase Contaminants
  Matt Middlebrooks, Filtrair, Inc.

  [ Open Abstract ]

  This presentation will provide a broad overview of pleated filters available for removal of gas-phase contaminants. It will describe the various constructions available on the market, including several unique or custom configurations, as well as the strengths and weaknesses of this type of filter compared to other formats and technologies. This comparison will then lead to the types of applications where these filters are most appropriate.

• Laboratory Evaluation of the Efficiency of Filtration Media
  Eve Henderson, AJE Testing & Research, Inc

  [ Open Abstract ]

  Understanding the performance of filtration media serves as a basis for better understanding how to develop or improve existing products for use in a variety of applications. Methods for evaluating the performance of filter media against gas/vapor contaminants on a laboratory scale by simulating a contaminated air stream and testing to evaluate the removal efficiency of the filtration products against those contaminants will be presented. The application and limitations of the laboratory methods and resulting data relative to that of full size filters will be discussed.
