TDA-5D Aerosol Generator


The 5D Aerosol Generator has been designed to provide operator convenience and improved performance. The 5C is ideal for certifying or testing HEPA filters or installations with air flows from 1,500 to 65,000 cfm. It requires an inert gas source and 115/230 volts @ 750 watts electrical service.


The 5D has all controls and displays grouped on the front panel away from the aerosol generator output nozzle. The unit has a large aerosol liquid capacity for operation up to 4 hours at full output without refilling. In addition, its digital temperature control allows the operator to set the unit for optimum conditions for the specific aerosol agent being used.

The 5D is capable of generating a wide variety of aerosol concentrations by discharging a controlled quantity of oil into a large heated area. The liquid is vaporized and condensed into a polydispersed aerosol while in the presence of a small amount of nitrogen delivered at approximately five pounds of pressure. The efficiency at which the aerosol is produced enables the 5C Generator, when used in conjunction with Analog or Digital photometers, to provide enough aerosol to leak test filtration systems from 1,500 to 65,0000 cfm. Systems larger than 6,500 cfm may be tested for leaks at less than 100 micrograms per liter when the photometer sensitivity is increased.
