Shown are deposits of mahogany dust on filters using three different
particle-size selective devices. Nylon cyclone presentation is a continual
building dot in the center of the filter. The aluminum cyclone (Cutsize is
approx. 4.6 micron) spreads the material over the filter more. The aluminum
cyclone can be readily adapted to 25mm cassettes. The horizontal elutriator has
very distinct pattern. The nylon cyclone is predominantly used by OSHA and most
of the USA.
