Flanders NESHAP 319 Specification Sheet

Flanders-Precisionaire offers several choices for
NESHAP filtration systems. These systems comply
with EPA (Environmental Protection Agency) Test
Method 319 as it applies to the National Emissions
Standards for Hazardous Air Pollutants (NESHAP).
Reference 63 Fed. Reg. 59 (March 27, 1998) and 40
C.F.R. 9, 63.
The EPA Test Method 319 is a testing protocol in
which potassium chloride and oleic acid are substi-
tuted for chromate paint. These chemical sub-
stances attempt to simulate dry and wet overspray
characteristics of the chromate paint. This testing
protocol verifies that an air filtration system has met
minimum efficiency requirements, under laboratory
conditions, utilizing potassium chloride and oleic
acid.
If a spraybooth existed before 1999, its filtration sys-
tem must comply with the two stage standards, and
if it was built after 1999, it must comply with the
three stage standards. Tables 1 and 2 show the
required compliance efficiency levels by micron size.
Recent legislation has shown that two or three
stages are not necessary as long as the final stage
has been certified to comply with the minimum effi-
ciency levels outlined in the table above..

Method 319: Determination of Filtration
Efficiency for Paint Overspray Arrestors
Quote: "For a paint arrestor system or subsystem
which has been tested by this method, adding addi-
tional filtration devices to the system or subsystem
shall be assumed to result in an efficiency of at least
that of the original system without the requirement
for additional testing. (For example, if the final stage
of a three-stage paint arrestor system has been test-
ed by itself, then the addition of the other two stages
shall be assumed to maintain, as a minimum, the fil-
tration efficiency provided by the final stage alone."
