The 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 incorporating filter-holding frames, says the manufacturer. Constructed of non-metallic components, the E-Series filter is designed to operate in humid conditions without rusting, corroding, or degrading in the air-handling system. An exclusive laminated enclosing frame with a composite header, says the company, offers high strength and excellent moisture resistance. This frame has no sharp edges, resists damage during shipment and installation, and weighs 33% less than metal frames, for ease of handling and freight cost savings, says the company. ¿ Farr Co.
