NESHAP 319
2 and 3 Stage Compliant System
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 substituted for chromate paint. These chemical substances 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 system 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 efficiency 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 additional 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 tested by itself, then the addition of the other two stages
shall be assumed to maintain, as a minimum, the filtration efficiency provided by the final stage alone.”

Flanders Precisionaire’s final stage options have
been tested and comply with NESHAP regulations.

Recommended Change-Out Procedures
1. When the entire system is installed, obtain a static pressure reading for the clean system
2. Change out the first stage when the static pressure rises a1.0 w.g. above the initial resistance.
3. Repeat this procedure until the static pressure remains at 1.0 w.g. even with a clean first stage
installed. At that time, replace the first and second stage. If a three-stage system is used, continue
replacing stage 1 and 2 until the third stage maintains a 1.0 w.g. reading with both clean first and second stages installed, then replace the entire system.
Initial pressure for a system can be estimated for an airflow velocity of 150 FPM by totalling the initial
pressure drop for each stage. This data is available in the technical performance data in this catalog.
