PES Program: Air Filtration

The October PES session will address the topic of Air Filtration on thee levels. The first will focus on particulate filtration with The Technology of Clean Air presented by Alan Veeck with the National Air Filtration association. The second part will focus on Gas-Phase Filtration with ASHRAE Distinguished Lecturer Chris Muller presenting Gas-Phase Filtration: Single Media or Multiple Media Systems: Which should be used for IAQ Applications. The third presentation will address Chemical, Biological, Radiological and Nuclear Filtration and will be presented by Dr. David Friday, Director or Research and Development at the Guild Associates.

Speakers:

Alan C. (Al) Veeck, CAFS, NCT II

TITLE: Technology of Clean Air

ABSTRACT: Air filtration is the correct tool for use with building IAQ, LEED and Sustainability. Just like any product, proper application is the key to proper air filtration and the Technology of Clean Air presents the principles, testing protocol (ASHRAE 52.2), and application information for engineers to design clean systems. The presentation will offer the chance to ask questions and get further information about air filtration.

Alan C. (Al) Veeck, CAFS, NCT II, Biography

Al Veeck is Executive Director of the National Air Filtration Association headquartered in Virginia Beach, Virginia. Al is a 1969 graduate of Butler University in Indianapolis, IN, with a degree in Business Adm. He began his 3rd career in the air filtration business in 1985 with Tidewater Air Filter as Vice President of Sales. While at Tidewater, he helped launch and served as General Manager for a new division of the company called BIO-TEC, Inc. BIO-TEC began as a biological safety and cleanroom certification company and, with the dominance of indoor air quality problems that started in the middle 1980's, quickly grew into a full-service indoor environmental testing company.

While with Tidewater, Al was elected President of the National Air Filtration Association (NAFA) in 1999. He also served and worked on the committee that wrote the first book on air filtration, NAFA Guide to Air Filtration, and was part of the first group of NAFA members to pass the national accreditation exam to become a NAFA Certified Air Filter Specialist (CAFS). He also worked on the committee to write the second text for NAFA entitled, Installation, Operation and Maintenance of Air Filtration Systems. In 1999, Tidewater was purchased by Flanders Precisionaire and Al served as the General Manager of the new company, called Airpure, until his resignation in 2002. When he resigned from Airpure, NAFA was searching for someone to manage the national trade association and asked Al to take the position. With prior experience in association work, Al accepted and has been NAFA's Executive Director ever since.

Al has been a Member of ASHRAE since 1985, serving on several Technical Committees and the Society Program Committee which is now the Conventions and Expositions Committee, and is a member of TC2.4.

Al received his NAFA Certified Technician (NCT) Level II accreditation in 2006, and teaches courses in biohazard containment, air filtration and sales and management.

Since 1980, he has been a certified instructor for Dale Carnegie Training® and over the ensuing 28 years, has attained additional certifications to instruct courses in High Impact Presentations® Leadership Training for Managers® World Class Customer Service® and more than 20 other courses.

TITLE: Gas-Phase Air Filtration: Single Media or Multiple Media Systems: Which Should Be Used for IAQ Applications?

ABSTRACT: More buildings are using gas-phase air filtration as part of their overall design for providing and maintaining acceptable IAQ. This trend is being seen in retrofit applications as well as new construction. Among the driving forces behind this are the increased awareness of their environment and how it may affect their well-being, legislative actions which are in effect or have been proposed and, of course, that ever-tightening noose being placed around the necks of buildings owners/managers to reduce energy consumption and provide a healthy "green" environment for occupants and visitors.

This discussion will describe the advantages and disadvantages of applying two general types of dry-scrubbing medias, granular activated carbon (GAC) and permanganate-impregnated alumina (PIA). It will also present the results of testing which shows that a dual-media system, either employing the media as a blended media product or in two separate filter beds, is more effective than single-media systems and should be used in the majority of applications using gas-phase air filtration for the maintenance of acceptable IAQ.

Christopher O. Muller Biography

Christopher O. Muller is the Technical Services Director at Purafil, Inc. and is responsible for technical support services and various research and development functions. Prior to joining Purafil, he worked in the chemical process and pharmaceutical manufacturing industries in quality assurance/quality control.

He has written and spoken extensively on the subject of environmental / indoor air quality and the application and use of gas-phase air filtration and counts over 100 peer-reviewed papers and articles, more than 30 seminars, and 7 handbooks to his credit. He has edited chapters in two handbooks on the application and use of gas-phase air filtration, wrote the chapters on gas-phase air filtration in the NAFA Air Filtration Handbook and Carrier Corporation's Applications Technical Development Program and a chapter on airborne molecular contamination in the Semiconductor Manufacturing Handbook published by McGraw-Hill.

He testified before OSHA on a proposed Indoor Air Quality Standard and has consulted on the preparation of Dutch and Italian governmental standards for indoor environments and has worked closely with many state and national agencies in the U.S. and abroad to develop and implement indoor environmental control strategies for airborne contaminants.

He is one of only 49 ASHRAE members named as a Distinguished Lecturer and is a frequent speaker at ASHRAE Chapter and Regional meetings, both domestically and abroad. He has also received the Distinguished Service Award. He is Chair of ASHRAE Standard Project Committee 145P, which is developing industry standards for assessing the performance of media and equipment used in gas phase air filtration systems.

TITLE: Chemical, Biological, Radiological and Nuclear Protection

Designing and building a system to provide chemical, biological, radiological, and nuclear (CBRN) protection for an enclosure requires rigorous attention to both filter and housing design. This talk will focus on chemical protection, highlighting those chemical vapors that provide the most severe challenges to filter design and filter installation (housing design). The talk will provide a quick review of military filters, the adsorbent that is used in all military filters, and the fundamental removal mechanisms of selected toxic vapors . An emphasis will be placed on system design and performance requirements imposed by extremely toxic vapors. Less toxic, but newly emerging threats typically referred to as TIC's (Toxic Industrial Chemicals) will also be touched upon.

Various filter options for NBC building protection will be discussed, along with the associated trade-offs concerning capital and operating cost, chemical concentration and duration, size and pressure drop. Positive-pressure collective protection systems employ these filters in buildings to remove airborne CBRN contaminants and other toxic compounds from the air, allowing critical missions to continue without the need for protective masks or suits. The talk will touch on CBRN protection systems, and integration with building HVAC equipment to provide protection to strategic areas or entire buildings. Protection strategy often include assessment surveys, equipment specifications, system installation, CBR filter installation and industry standard leak testing.
