General
SwissAire is a very high strength, synthetic media
bag filter. Pockets are nearly rigid, making them
self supporting for full media use and no pocket sag.
Pockets are also fully welded instead of stitched.
That means less chance of pin-hole leaks and very
high blow-out strength. Headers on SwissAire bag
filters are all 16 gauge galvanized steel, not plastic
that can crack or warp.
SwissAire synthetic, self supporting bag filters are
designed for use in most commercial or industrial
HVAC systems where medium to high efficiency filtration is required. SwissAire Filters are available in
minimum efficiency levels of 50%, 60% and 90%
per ASHRAE Standard 52.1 test methods. Offered
as MERV 8-15 per ASHRAE Standard 52.2
SwissAire bag filters are UL 900 Class 1 listed.
Installation Considerations
SwissAire bag filters may be installed in Flanders
ASTRl Holding Frames, K-Trac Filter Framing
Modules, Sureseal Side Access Housings, or in
similar existing hardware.
SwissAire
Self Supporting Synthetic Media Bag Filters
Bulletin PB1104-1206
ASTR Holding Frames are riveted together to form
a bank and may be installed for upstream or downstream service. K-Trac Filter Framing Modules are
especially suitable for medium to large built-up filter
banks. Smaller systems and systems with minimum
upstream access space are best served using
Sureseal Side Access Housings.
Physical Data
Media: A nearly rigid, high strength synthetic medium.
- Progressive density fiber matrix designed for high
dust holding capacity.
- 100% synthetic medium performance results
from strictly mechanical particle collection mechanisms. Performance of the product is not afffected
by preconditioning step proposed to ASHRAE 52.2
Pocket Retainer: Corrosion resistant steel or aluminum
Header: 13/16” wide corrosion-resistant steel
Actual Header Face Size: Nominal size less 5/8” (e.g., a
nominal 24” x 24” filter header is actually 23-3/8” x
23-3/8”)
Important Features
• Nearly rigid pockets are self supporting and allow
for full media use with no pocket sag
• 100% synthetic media
• Low initial pressure drop provides longer life.
• Welded pockets, no stitching for better integrity and
higher blowout strength.
• Wide range of cartridge depths, efficiencies
and operating capacities are available.
• MERV 8-15
• UL 900 Class 1

Application Guidelines
SwissAire bag filters should be installed with pockets vertical wherever possible. It is acceptable to
install 24” x 12” face size filters with pockets horizontal if necessary to meet the size requirements
of the filter banks.
Gasketed Headers
SwissAire bag filters installed in Flanders K-Trac
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 warrants their use with 50% or 60% filters.
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.
