This expanded line of high-efficiency air filters offers the advantages of rigid filtration in an environmentally friendly design, the company says. New E-Series Riga-Flo®/PH (peripheral header) air filters may be installed in all types of side-access filter housings using tracks, and in units with filter-holding frames. Made of nonmetallic components, the filter is designed to operate in humid conditions without rusting, corroding, or degrading. At disposal time, filters can be compacted or incinerated without producing harmful contaminants, says the company.
