TDA-6D Aerosol Generator

6D Aerosol GeneratorA tough, portable solution
The 6D is a small, light, and rugged portable, self-contained Laskin-Nozzle aerosol generator. It is ideal for testing a wide variety of filter systems with airflow’s up to 2,000 cfm by generating a poly-dispersed, sub-micron aerosol. Applications include workstations, negative-pressure filtration units, bio¬≠logical safety cabinets, ceiling modules, and more.

The 6D can also be used for testing positive pressure systems using an optional hose adapter. On-site routine maintenance is easy. And its integrated compressor makes implementation simple – all you need is a power source.

Performance Guaranteed
6D aerosol output is regulated with a standard issue calibrated pressure gauge; guaranteeing 20psi across the nozzle as specified in industry standards. The 6D complies with all applicable electrical and safety requirements and is supplied standard with the CE mark.

Easy to use
Integrated liquid fill sight glass, drain port, and power cord storage make operating, transporting, and  storing the 6D simple and easy.

Optional Hose Adapter Kit
A hose adapter kit, used to introduce aerosol remotely, connects easily to the standard outlet using the sanitary flange or simple NPT connection.

Aerosol output calculation
The 6D includes a total of 1-1/2 Laskin nozzles. Each “full” 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) divided by the total airflow (CFM)

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.
