A Grade Above
ATI offers the highest quality, industry-standard oil reagents for use in conjunction with oil aerosol generators. Our reagents are
used for in situ leakage testing and production quality control efficiency testing of high efficiency air filters. ATI oil aerosol reagent products are suitable for government, nuclear, and FDAregulated testing applications.

A Choice of Reagents
ATI offers both DOP (Di-2-ethyl hexyl phtha-late/DEHP) and PAO4 (poly-alpha olefin) reagents for use in filter testing applications.

DOP Reagent
ATI products include DOP-based reagents (Chemical Abstract System ID 117-81-7) commonly used in U.S. Department of Energy testing and NIOSH respirator cartridge developmental and quality assurance testing.

PAO-4 Reagent
ATI also offers four-centistoke PAO. These reagents offer a U.S. Food & Drug Administration-approved alternative to DOP in FDA-regulated filter leakage testing applications. PAO is approved by the U.S. Army Surgeon General and is used by the United States military as a substitute for DOP in their filter and mask testing processes.
