- Abstract
- An improved vacuum pneumatic conveying system has been developed for filling dry chemical fire extinguishers of 150 lb and larger capacity. It features more rapid filling and eliminates the lifting and dumping of cans, with its attendant dust nuisance. The main components are a 1-1/2 horsepower industrial type vacuum cleaner and an especially designed separator cap which fits on the fill-cap threads and serves to separate the powder from the conveying air stream.
