TDA-6C
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.
The
TDA-6C features several improvements including rugged stainless steel
construction, large fill port, jet and pressure 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-6C
Features
The TDA-6C is the latest design in rugged, lightweight Laskin nozzle generators from ATI. The TDA-6C is a self-contained aerosol generator that requires only a suitable voltage source to create polydispersed sub-micron oil aerosol.
The TDA-6C has 6 Laskin nozzle jets. When its total output at 20 psig is diluted by 200 cfm of air, the aerosol concentration is approximately 100 ug/l. A valve permits the unit to be operated with either 2 or 6 nozzle jets, providing a wide range of aerosol concentrations.
The
TDA-6C is recommended for testing systems with airflows of 2,000 cfm and
lower. It is ideal for workstations, 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 not readily available.

TDA-6C Aerosol output calculation
This unit includes a total of 1 1/2 Laskin nozzles incorporated into the cabinet. Each nozzle consists of four jets located at the nozzle tip, for a total of six jets. The aerosol concentration depends on the compressed air pressure and flow available for consumption by the nozzle. With 20 psig applied, each jet emits 18.75 slpm of air containing 1,275 ug/l of aerosol. When this aerosol is diluted with 135 cfm of air, the aerosol concentration becomes approximately 25 micrograms per liter. The equation below is for purposes of calculating the aerosol output in micrograms per liter (ug/l) when 20 psig is applied to the nozzle jets.
3,375 x (# of jets being used)
NOTE: 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.
