ATI Oil Reagents
Printable Specification Sheet
A Grade Above
ATI offers the highest quality, industrystandard 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.
A Choice of Reagents
ATI offers both DOP (Di-2-ethyl hexyl phthalate, aka DEHP) and PAO-4 (polyalphaolefin) reagents for use in filter testing applications.
DOP/DEHP 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. (Domestic United States sales only.)
PAO-4 Reagent
ATI also offers four-centistoke PAO-4 (Chemical Abstract System ID 68649-12-7 and/or 68037-01-4). 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.
Product Configuration
ATI Oil Aerosol Reagents are available in both 1 gallon and 5 gallon containers. Larger volumes may be available upon request.
