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..

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

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.
