Precisionaire PB1104 Air Cleaner User Manual


 
Guide Specifications
Application Guidelines
SwissAire bag filters should be installed with pock-
ets vertical wherever possible. It is acceptable to
install 24” x 12” face size filters with pockets hor-
izontal if necessary to meet the size requirements
of the filter banks.
Gasketed Headers
SwissAire bag filters installed in Flanders K-Trac
Filter Framing Modules or Sureseal Side Access
Housings require polyfoam gaskets on opposite
header sides to prevent air bypass. To specify
SwissAire bag filters with gasketed headers, add
suffix ”SA” (side access), “GU” (upstream), “GD”
(downstream) and “GS” (sides) to model number.
Prefilters
Properly selected bag filters without prefilters will
generally require changeout annually in typical
HVAC applications. Because of the frequent
maintenance expense and increase in fan kW
input using prefilters, they are often recommended
with 90% efficient SwissAire final filters. However,
the energy cost to operate a prefilter seldom war-
rants their use with 50% or 60% filters.
1.0 General
1.1 Medium and high efficiency self-supporting filters
shall be SwissAire extended surface type as man-
ufactured by Flanders.
1.2 Filter sizes, efficiencies and capacities shall be
as scheduled on the drawings.
2.0 Filter Construction
2.1 Filters shall be constructed of 100% synthetic
media of sufficient rigidity to maintain self-support-
ing pockets.
2.2 Open area on the filter face for air passage shall
not be less than 90%.
2.3 Pockets shall be 100% welded, with no stitching to
provide protection against leaks and extra blow-out
strength.
2.4 Pockets shall be bonded to corrosion-resistant
steel casings and assembled into a corrosion-
resistant steel header.
2.5 Filters shall be UL 900 Class 1 rated.
3.0 Performance
3.1 Initial and final resistances shall not exceed the
scheduled values.
3.2 Media area must equal or exceed that of the spec-
ified filter.
3.3 The average efficiency shall be as determined
by the ASHRAE Standard 52.1 and 52.2 test
methods.
3.4 The manufacturer shall guarantee performance as
stated in its literature within tolerances as outlined
is Section 7.4 of ARI Standard 850.
Performance values shown in this publication may be averages or estimates intended to generally represent a product style.
