ATI - Oil-based Aerosol Reagents

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.

PAO-4 Reagent
ATI offers PAO-4, a four-centistokes PAO (Chemical Abstract System ID 68037-01-4). This reagent offers 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.

Ondina X 420 (EMEA Only)
Ondina X 420 is the latest version of Ondina, manufactured by
Shell. Its CAS (Chemical Abstract System) Number is 1262661-
88-0. The earlier Ondina EL version was listed in ISO 14644-
3:2005 as one of the typical substances used to generate test
aerosols, and X 420 continues to be widely used for in-situ
testing of HEPA filters.

ATI oil aerosol reagents are available in both 1-gallon and 5-gallon containers (2-liter and 20-liter) containers. Larger volumes may be available upon request.
