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 FDA-regulated testing applications.

ATI offers both DOP (Di-2-ethyl hexyl phthalate/DEHP) and PAO-4 (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-centistokes 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.

ATI Oil Aerosol Reagents are available  in both 1 gallon and 5 gallon containers. Larger volumes may be available upon request.
