TDA-4B Aerosol Generator
Description
ATI manufactures portable Laskin nozzle aerosol generators
which produce a sub-micron polydispersed oil mist aerosol
in concentrations from 10 to 100 micrograms per liter (ug/l)
at air flows from 50 to 8,100 cfm.
Aerosol generators and photometers are used to integrity
test or locate leaks in high efficiency air filtration systems.
Filter manufacturers use this equipment to scan ULPA and HEPA
filters to verify they are free from manufacturing defects.
Filter certifiers use this equipment to insure that filters
were not damaged in shipping and have been installed properly,
eliminating any leakage.
With the proper generator and photometer combination, filter
deficiencies such as pinholes, thin spots, gasket leaks, frame
leaks or seal problems can be quickly and quantifiably pinpointed
and corrected thus protecting product and personnel.
Both the TDA-4B and the TDA-4BLite feature several improvements
including rugged stainless steel construction, large fill
port, individual nozzle control, and a 3" standard sanitary
outlet fitting. An optional hose adapter, part # 9300100,
is available for introducing the aerosol into positive pressure
systems.
Features
The TDA-4B is the latest design in rugged, lightweight Laskin
nozzle generators from ATI. The TDA-4B is a small, compact
aerosol generator which requires only a supply of clean, compressed
air to create polydispersed sub-micron oil aerosol.
The TDA-4B has 6 Laskin nozzles. Three valves permit the unit to
be operated with 1 to 6 nozzles, providing a wide range of
aerosol concentrations.
The TDA-4B is recommended for testing systems with air flows
of 8,100 cfm and lower. It is ideal for work stations, Negative
Pressure Filtration Units, biosafety cabinets, ceiling modules,
small or portable cleanrooms, or HEPA filter units in installations
where an adequate supply of clean, compressed air is readily
available.

if less than 20 psig is used, the output concentration wil decrease.
* If using more than 2 nozzles, upstream concentration should be measured
