There are four sizes available to treat airflows up to 3,000 cfm in a single system. These units are designed to allow selection of the optimum size to economically solve air treatment needs and are constructed with features that allow for ease of installation and operation.

High-Efficiency Particulate adsorber filter Housings

High-Efficiency Particulate Adsorber (HEPA) housings are commercial and industrial duty filter housings designed to remove particulate contaminants from air streams. HEPA housings (HH) are utilized when 99.9% or greater particulate free air is required. They can be added to existing HVAC systems for upgrade to HEPA level filtration. When the primary concern is particulate contamination, these housings are a direct fit. In some cases, the purified air can be recirculated resulting in reduced make-up air requirements and energy savings. Please note that The Center for Disease Control (CDC) recommends against recirculation of HEPA filtered air for biological substance. HEPA housings are completely factory assembled and self-supporting.
