D Series Aerosol Diluters

Designed for the specialized needs of the high efficiency particulate (HEPA/ULPA) filter testing industry, the D Series aerosol diluters enhance the effectiveness of optical particle counters by diluting the upstream concentration of aerosol to measurable levels.

An Industry-Specialized Solution

Designed for the specialized needs of the high efficiency particulate (HEPA/ULPA) filter testing industry, the D Series aerosol diluters enhance the effectiveness of optical particle counters by diluting the upstream concentration of airborne particulate to measurable levels between the upstream sample and a particle counter.
Installed between the aerosol source and a particle counter, these diluters minimize pressure drop and aerosol loss while preventing saturation of the particle counter.

Versatile Technology

The D series aerosol diluters are compatible with any 1 cfm particle counter. They are available in 10:1 and 100:1 versions (possible alternate sample flow rates available. Contact ATI Customer service.) and work with any type of aerosol challenge, including PSL, PAO, DOP and NaCl. Each and every D Series Diluter is configured to customer specific requirements.

Available 10:1 and 100:1 D Series Diluters can be plumbed in series to achieve additional dilution configurations.
