(3) High-pressure, low-air-volume systems with high ratio of perlite to air (1-15 psi, ratio of 1 /3 through 1/10). A vacuum can be drawn on a storage silo or cryogenic vessel (Fig. 1) and the perlite is pulled through a hose or pipe, to be settled out in the tank without the use of a cyclone. As shown here, this is a low-pressure system.
