Portable Laskin Generator Compressor Requirements

The TDA-4A, 4Blite & 4B Aerosol Generators use Laskin Nozzles to generate aerosol. These require significant amounts of compressed air. Each nozzle, when operating at 20 psig, requires 2.65 actual cubic feet a minute (ACFM) of compressed air using DOP/DEHP, and 2.88 ACFM when operating at 23 psig using PAO-4. If the number of the nozzles is increased, the quantity of compressed air will also increase.

5 14.4 408 13.25 375
6 17.28 489.6 15.9 450

The maximum air pressure required is approximately 18 ACFM at 23 psig. This air compressor capacity requires a relatively large, non-portable compressor. Operation of these generators using less than 3 nozzles is possible with a portable compressor of approximately 1-1/2 HP.
