A Flexible Solution
The TDA-4B family of aerosol generators produce an industry standard true Laskin
III-A repeatable aerosol and feature adjustable aerosol concentration output to
meet multiple application requirements. These generators are used in conjunction
with an aerosol photometer to measure the aerosol penetration of an individual filter or
filter system, typically to identify, quantify and repair leaks. Aerosol concentration output
varies by generator model; however concentrations can be achieved from
100 ug/l down to 10 ug/l at airflows ranging from 405 to 8,100 cfm*.

Rugged Convenient Design
The TDA-4B family features rugged stainless steel, with easily cleanable construction, a
large fill port, jet and pressure control, and a standard three-inch sanitary fitting outlet colla
