Portable Laskin Generator Compressor Requirements

The 4A, 4B, and 4B Lite 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 nozzles increases, the quantity of compressed air will also increase.

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