FOR USE AS AN INTAKE FILTER
These self-supportive panels are made from the
SAR-1 media. A wire support is sealed between the
SAR-1 media layer and a 1/2” polyester prefilter
layer.
The filter media is made from a blend of polyester
fibers coated with an ecologically sound tackifier and
a scrim layer on the downstream side for added
strength and rigidity. The polyester fibers are fused
together through a special low-melt production line.
SAR-1 is made without the use of PVC or other
unfavorable chemicals. In a heated environment, it’s
these chemicals and/or the tackifier and scrim which
can cause fiber discharge and heavy discoloration
through the media (the “browning effect.”) In addi-
tion, the SAR-1 scrim layer resists discoloration in a
normal environment when compared to competitive
brands.
The scrim layer also helps reduce any fibers from
breaking off of the media during handling and instal-
lation. The scrim increases the strength of the
media and eliminates any sagging when loaded with
contaminants.
The wire support is made from a 9 gauge galvanized
wire with one to two cross pieces per frame. The
two media layers are dielectrically welded together
which seals the wire support inside the media layers.
The panels are available in single panels using one
single wire frame up to 2-” x 50” or in link panels
using two or more wire frames and one continuous
piece of media for easy installation. Special sizes
are available upon request.
One important feature of a panel is the quality of the
seal. If the media layers are not properly bonded
together, the filter can break apart during use and
cause mechanical problems in the booth. To prevent
this possiblity, the SAR-1 uses a full 1/4” sealing sur-
face for the is filter. Competitive products traditional-
ly use a 1/8” seal.
