The QA (Quality Assurance) series of in-line pneumatic sifter/screeners was developed to answer the quality assurance and HACCP needs of food, pharmaceutical, and chemical operations. Manufactured with a higher level of sanitation in mind, the QA series has smooth surfaces with fewer weldments and snap-on neoprene gaskets that do not use adhesives. These sifter/screeners are designed to be directly inserted into a vacuum or pressure pneumatic conveying system, eliminating the need for additional equipment. Their pneumatic sieve compression system speeds access for inspection and maintenance, while securely sealing the nest-together sieve rings. The Tru-Balance drive mechanism straddles the sifter’s center of gravity keeping the sifting motion in the machine. Great Western Mfg.
