Purafil Purafilter
The Purafilter is a combination chemical and particulate filter designed to replace existing particulate filters in retrofit or rework applications. Purafil engineers are the first to successfully suspend sodium permanganate adsorbents in a bi-component fiber matrix.
Chemical filtration systems utilizing sodium permanganate remove a broader range of contaminants than carbon-only filters and exhibit higher efficiencies. Because of the Purafilter’s broad-spectrum removal capabilities, it is the only chemical filter capable of meeting the stringent requirements of ASHRAE 62’s Indoor Air Quality Procedure.
Read MoreThe bi-component fiber matrix, or filter, does not require the use of adhesives, so adsorbents are fully exposed for reaction with gaseous chemical contaminants and odors.
Purafil offers two grades of the Purafilter: Purafilter-Commercial Grade for light to moderate duty applications and Purafilter-Heavy Duty for high contaminant load applications. All standard sizes are available.
Adsorbents are evenly distributed throughout the filter structure to assure the highest filtration efficiencies. The Purafilter offers a higher media loading than other chemical filters, enabling a longer service life and reduced maintenance.
Features and Benefits:
- Contains up to 10 times the media of activated carbon filters
- Removes more gaseous chemicals and odors than activated carbon
- Removes gaseous chemicals and solid particulates
- Adhesive-free filter design
- Minimized by-pass and high removal efficiency
- Purafil SP Media will not desorb
- Low pressure drop
- Long filter life
- Reduced maintenance
- Improved indoor air quality
