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.

Model	# Nozzles	PAO-4 (23 psig)		DOP (20 psig)
		ACFM	ALPM	ACFM	ALPM
TDA-4Blite	1	2.88	81.6	2.65	75
	2	5.76	163.2	5.3	150
	3	8.64	244.8	7.95	225
TDA-4B	1	2.88	81.6	2.65	75
	2	5.76	163.2	5.3	150
	3	8.64	244.8	7.95	225
	4	11.52	326.4	10.6
	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.
