Camfil Farr Micretain® air filters are manufactured from the highest quality components, under demanding quality control conditions, for application in critical environments where sub-micron particle capture is important.
With an efficiency of 95% on 0.3 micron particles, the Micretain will capture 99% of all bacteria1. The Micretain also offers a lower resistance to airflow than HEPA filters. Typical applications include medical facilities, pharmaceutical manufacturing, electronic component manufacturing, food and dairy processing facilities, and many other locations where ultra-clean air is a requirement.
Each Camfil Farr Micretain includes:
- A galvannealed 16-gauge steel frame to create a durable, dimensionally-stable corrosion-resistant enclosure.
- X-body frame assembly (assembled without the use of penetrating fasteners) to ensure leak-free performance throughout the life of the filter. Our unique urethane potting process completely encapsulates the filter pack within the enclosing frame.
- Safe-edge corrugated aluminum separators to ensure uniform airflow throughout the media pack and maintain pack stability. The edges of the separators are hemmed for added strength and to protect the media from damage during manufacture, shipping and installation.
- Microfiber all-glass media to provide efficiency to specified performance values. The media is highly-resistant to moisture in high-humidity environments.
- A one-piece seamless urethane gasket (or a closed-cell neoprene gasket with unique dovetailed junctures) to ensure a leak-free filter-to-holding mechanism seal.
- Available in nominal 12” depth or compact 6” depth.
Each unit includes a label noting efficiency, penetration, rated and performing airflow, pressure drop and a serial number for quality assurance.
