ASHRAE
52.2-2007 ASHRAE 52.2 now incorporates the requirements of
arrestance and dust-holding capacity from Standard 52.1. It also adds a new informative
appendix that provides an optional method of conditioning a filter using fine
KCI particles to demonstrate efficiency loss that might be realized in field
applications). Update - A new test report on the
industry standard Camfil-Farr 30/30 pleated filter is now available. This 30/30 test report portrays
consistent mechanical particle capture efficiency throughout the 12 particle
size ranges of the test. In fact, at the geometric mean of 3.46-micron the
30/30 reaches an efficiency of 70.5% after the initial conditioning step. The 2008 revision to ASHRAE 52.2
was published this week. It includes a new conditioning method, arrestance
and dust holding capacity. ASHRAE has published these changes as Addendum B
to 52.2-2007. They will not be issuing
a “2008” version of the standard. Appendix J has been added as part
of Addendum B to 52.2-2007. To view the ASHRAE 52.2-2007 Appendix J results
on the 30/30. Click here to see the report. Note that after using Appendix J
the 30/30 still exceeds 66% at the geometric mean of 3.46-micron. ASHRAE 52.1-1992 The public review has ended with only 4 comments,
all supportive of withdrawing the Standard. Per Mark Weber at ASHRAE
Standards, it will now be on the agenda in ASHRAE Standard 62.1 Table

panel of judges comprised of professional engineers who regularly design and
specify HVAC, electrical, fire protection, and plumbing systems. Consulting-Specifying
Engineers readers then voted to determine the ranking of the finalists as
gold, silver, or bronze winners. Consulting-Specifying Engineers
