Select Specialty Hospital

A NAFA Member since 1982, Tom Riddell, CAFS, NCT II of Air Filter Sales and Service (AFSS) in Jackson, Mississippi, teamed with Gary Touchton, Director of Plant Operations and Chandler Ewing, CEO of Select Specialty Hospital to correct an indoor air quality issue. Select Specialty Hospital is a 53-bed extended care facility that helps extremely critical patients who have been transferred from other medical facilities. The facility was experiencing extreme moisture in the HVAC system which resulted in high spore counts in the building. Improper and inadequate coil cleaning was determined to be the problem and AFSS installed ultraviolet germicidal irradiation (UVGI) equipment to supplement the MERV 8 prefilters and MERV 15 final filters. The UVGI equipment shines light in the ultraviolet spectrum completely within the coils to kill biofilm, bacteria and mold on surfaces and deep within the coil. This solution removed the moisture from the system and eliminated the problem. All pressure gauges were refurbished and a planned air filter maintenance program was established with AFSS utilizing NAFA Certified Technicians.

SouthLand Park, Buildings I – IV

The SouthLand suburban office centre complex is one of Calgary Alberta’s largest premier office parks owned by Morguard Investments, Ltd., and was built in 1978, 1980, 1981 and 2008 respectively. The campus has a combined 882,000 square feet of multi-tenant office space. Each building has a different HVAC system and, working with Sharon Needham, CAFS Account Manager of B.G.E. – The Filter Shop, Lindsay Gavel and Eric Poirier, Operations Supervisors of SouthLand were looking for ways to improve the air quality in each building.

Building I had issues with pocket filters that did not inflate properly during operation causing ruptures in the filter pockets. A change and upgrade to MERV 13 rigid cell filters increased the square footage of filter area from 42 to 90, lowering pressure in the system and increasing the life-in-service of the filters.

Building II presented an opportunity to upgrade filtration to MERV 8 prefilters and MERV 13 final filters, matching the filter efficiencies in the other buildings.

Building III had a filter bank that allowed for an upgrade from pocket filters to MERV 13 minipleat v-cell filters, increasing the filtering surface area from 46 to 130 square feet of media. This allowed for a decrease in system pressure from the filters of 0.50” w.g. to 0.22” w.g. resulting in energy savings and long filter service life. Building IV also upgraded to MERV 13 minipleat v-cell filters with a corresponding decrease in system pressure and longer filter service life.

In all buildings, gasketing was removed and replaced where necessary, and system pressure measuring devices were recalibrated. An accurate air filter maintenance service log is kept on units in the complex.

The University of Kansas

Medical Center Bioscience and Technology Business Center Breidenthal Building
The University of Kansas Medical Center is a non-profit academic institution and is the region’s only nationally verified Level I Trauma Center. The Breidenthal Bioscience & Technology Business Center, Kansas City, UT is a unique business incubator that helps promote innovation, entrepreneurship, and commercialization of university research. Robb Palmer, North Zone Manager along with Eric Johnson, Facilities Specialist worked with NAFA Member Dick Ballard, CAFS of Koch Filter Corporation to increase the indoor air quality by upgrading their filter system to MERV 15 minipleat v-cell filters. This upgrade not only increased the filter efficiency for contaminant removal but allowed for a lowering of the system pressure resulting in significant energy savings. Gasketing was removed and replaced to eliminate air bypass and pressure monitoring devices were installed and recalibrated and accurate filter change schedules were initiated. In addition, activated carbon filters were installed in areas that were experiencing an odor issue from research work being performed. This addition corrected the odor problem.

Wells Fargo Advisors

The Wells Fargo Advisors building operated by CBRE, St Louis, MI set a goal of operational savings by reducing filter changes, shipping and inventory costs, and energy savings for their VFD HVAC systems, after a recent building addition and renovation which increased their building capacity to 2.3 million square feet. Working with Joe Dardis, CAFS of 3M Purification, Gary Tappella, Lead Building Engineer for the facility, replaced the existing filters which were changed every 90 days and rigid box filters that were changed 1-2 times per year, with MERV 12 minipleat v-cell filters. This change allows for increased filter surface area resulting in system pressure reduction for energy savings and longer in-service filter performance. Gasketing incorporated on each filter eliminated air bypass and reduced particle counts downstream. Results from the upgrade are a reduction in system pressure for energy savings, filter service life now exceeding 12 months which reduced inventory and shipping costs, and higher levels of contaminant removal with the MERV 12 filters. Dardis is continuing to monitor the system pressure and particle counts so that correct filter change schedules can be established.

Williams Tower

Williams Tower, Houston, TX is a Hines Interest property with 64 floors and over 1.4 million square feet of multi-use space. With an eye to LEED accreditation, Williams Tower’s Mike Taylor, III called upon the service of Phil Maybee, CAFS of The Filter Man to accomplish the goal. First identified were deficient filtration and gasketing on most all units along with poorly designed sealing methods for the filters. Because of this, high pressure developed in the system over several years and coil replacement had to be undertaken. Filter plenum insulation had deteriorated and this was replaced with new insulation. Filter efficiency was upgraded to 4” MERV 13 minipleat and v-cell filters to negate coil and indoor air contamination and gasketing and filter holding devices were replaced. Staff training was also completed by Phil Maybee. Pressure gauges have been installed/replaced and an ultraviolet germicidal irradiation system has been installed for control of bacterial odors from a sump system located in the basement. A filter maintenance guide has replaced the filter change schedule which had been previously done on a time basis. Finally, an operations contract for filter service was completed using NAFA Certified Technicians for service.
