Outside Plant Filters – Series 2

Eliminate dust, water, wind driven rain and salt fog ingress

The UAF Outside Plant Series 2 filter utilizes newly developed high efficiency media technology that offers protection from dust, wind-driven rain and salt fog ingress at higher air flow and lower initial resistance than similarly rated filters. The OSP 2 filter provides the cost-effective answer for enclosure engineers looking to take advantage of direct air-cooling systems for electronics equipment protection. Cabinets installed in harsh environments for telecommunications, power generation, video or LED displays, kiosks, military/defense, and any other industrial or commercial outdoor enclosure can now use outside air vented, energy efficient direct air-cooling systems in place of costly, inefficient closed air-to-air heat exchangers.

UAF OSP 2 filters provide superior water and airborne contaminant protection in compliance with stringent industry enclosure standards including GR 487, NEMA, IP, MIL-STD-810E in an assembly that is RoHS compliant and UL900 rated. UAF developed the OSP 2 media to achieve the same efficiency of comparable filters with up to 30% lower initial resistance and better pleat integrity under extreme loading, effectively allowing our customers to achieve significant cost savings through decreased power consumption and longer filter life. UAF’s unique OSP 2 filter design incorporates a cleanable/replaceable pre-filter to extend the life of the high-efficiency media in a custom, cost effective, integrated assembly.

In addition to high efficiency Outside Plant filters, Universal Air Filter Company also manufactures several other filtration solutions for use in outdoor environments.
