Smith HEPA filters are designed to meet the highest level of filtration needed in application such as: pharmaceutical, hospital, electronic component manufacturing, aerospace, food processing and all facilities that must have HEPA filtration.
All HEPA filters are manufactured to Federal Mil Spec 282 and UL 586. They are tested and scanned
on .03 micron, in accordance with IEST-RP-CC034.1. Each filter is inspected, tested and scanned before it
leaves the lab.
The ASHRAE Filter is a HEPA type filter, available in Merv 14, Merv 13 and Merv 11. The filter is constructed of high strength, water resistant, glass micro-fiber paper in a pleated design. A corrugated aluminum separator is placed between each pleat, to prevent the pleats from touching. The media pack is installed into a heavy 24 ga. galvanized steel enclosure frame. A sealant is then applied to provide a positive seal between the media and the frame. The ASHRAE filter provides high efficiency filtration where clean air environment is a necessity. This includes, hospitals, laboratories, office buildings, food and beverage processing plants, and other applications that require high efficiency without needing the DOP rating. Available in 6” and 12” depths, 12 x 24 and 24 x 24 in each Merv rating. Headers available upon request.
The MINI PLEAT Filter is a HEPA type filter, available in MERV 15, MERV 14, MERV 13 and MERV 11 efficiencies. Made with special media, designed to capture both large and small particles with minimum airflow restriction. Tightly pleated, this media has 5 times the surface area as the regular pleated filter. The increased surface area means better filtering capabilities and longer filter life. Designed for use in hospitals, air purifiers and computer clean rooms.
MERV stands for Minimum Efficiency Reporting Value. This system is designed by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). MERV ratings are derived from the ASHRAE 52.2-2012 test which groups the particles sizes into three categories. Small (.3-1.0 microns) Medium (1.0- 3.0 microns) and Large (3.0- 10 microns). MERV ratings range…
