Medium efficiency pleated panel filter. Contains up to 16 pleats per linear foot. Radial pleat construction for minimum pressure. Available in U.L. Class 2 or 1, in 4”, 2” and 1” depths. Nonwoven cotton/synthetic blend media.
Camfil Farr UL Class 1 30/30® filters provide ASHRAE efficiency for those applications requiring a UL Class 1 rating when evaluated under Underwriters Laboratory Standard 900.
The Class 1 30/30 media is manufactured from a unique blend of high density glass microfibers which are laminated to an all-glass mesh backing. Formed into a radial pleat, this combination provides a MERV 8 ASHRAE efficiency when evaluated under ASHRAE Standard 52.2 -1999 and a 25-30% average efficiency when evaluated under ASHRAE Standard 52.1 – 1992.
The radial pleat is maintained by a welded wire grid, spot welded on one-inch centers, treated for corrosion resistance and bonded to the media to prevent oscillation. An enclosing frame constructed of a non-flammable board with integral diagonal support members assures filter rigidity in virtually any demanding application. The media pack is bonded to the enclosing frame and diagonal support members to prevent air bypass and assist in frame rigidity. The 30/30 is guaranteed to 2.0” w.g. without failure of the media pack.
Available in 2” or 4” deep configurations, the Class 1 30/30 is ideal for commercial, industrial, medical, institutional or any other application where UL Class 1 is required and improved air quality is a concern.
