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 @ 20 psig.
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-4B Lite feature several improvements including rugged stainless steel construction, large fill port, individual nozzle control, and a 3" standard sanitary fitting outlet. An optional hose adapter, part # 9300100, is available for introducing the aerosol into positive pressure systems.
TDA-4B Lite Features
The TDA-4B Lite is a smaller, lower capacity version of the TDA-4B that still retains all the improved features. The TDA-4B lite was specifically designed for use in biosafety cabinets. Its small size and low cost make it the ideal generator for biosafety cabinet testing and HEPA filter vacuums.
The TDA-4B Lite has 3 Laskin nozzles. When its total output at 20 psig is diluted by 405 cfm of air, the aerosol concentration is approximately 100 ug/l. Two valves permit the unit to operate with 1 to 3 nozzles to provide a wide range of aerosol concentrations.

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