The Camfil Farr LH Absolute® offers HEPA level efficiencies for pharmaceutical, medical, and research facilities. Its wood frame makes it ideal for disposal through incineration or compacting.
A high-quality, medium-density fiberboard (MDF) frame assembled with Camfil Farr’s unique potting process.
Each Camfil Farr LH Absolute® includes:
- Camfil Farr’s filter-pack-in-sealant construction eliminates the use of penetrating fasteners, ensuring leak-free performance throughout the life of the filter.
- Safe-edge corrugated aluminum separators 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.
- Water-resistant, high-strength, micro glass fiber media in efficiencies ranging from 99.97% to 99.99% on particles 0.3 microns in size. With up to 60% more media area, the LH has a lower average pressure drop, requires less energy to move air through the filter, and has an extended service life when compared to standard capacity HEPA filters.
- A one-piece seamless urethane gasket to ensure a leak-free filter-to-holding mechanism seal. (A neoprene dove-tailed gasket is also available).
Every Camfil Farr LH Absolute filter is individually tested per IEST Recommended Practice. Each filter is labeled noting tested efficiency, pressure drop, rated and performing airflow and a unique serial number for unit tracking and quality assurance.
