NESHAP Standards

National Emissions Standards for Hazardous Air Pollutants (EPA)

The EPA National Emissions Standards for Hazardous Air Pollutants (NESHAP) mandated that a new filtration test method be established to determine the efficiency of a filter to remove hazardous pollutants from paint overspray. The EPA guidelines went into effect on September 1, 1998 and continue to set the standard for paint overspray collection systems today. The test method to determine compliance is Test Method 319 and all ATI NESHAP filter products are tested in accordance with this standard.

ATI developed the first NESHAP approved filtration systems in 1998 and today we offer a variety of different systems designed to meet your individual needs. Click on the links below to learn more about two of ATI's most popular NESHAP systems. The OSM-100 system (two stage) is perfect for exceeding requirements for existing paint booths and the A-3000 system (three stage) is ideal for new paint booth systems.

EPA NESHAP guidelines for overspray collection in aerospace painting and reworking facilities and industrial painting applications are as follows:
Existing Paint Booths New Paint Booths
Particle Size
Efficiency Particle Size
> 5.7 > 90% > 2.0 > 95%
> 4.1 > 50% > 1.0 > 80%
> 2.2 > 10% > .42 > 65%
> 8.1 > 90% > 2.5 > 95%
> 5.0 > 50% > 1.1 > 85%
> 2.6 > 10% > .70 75%
