The PGR series of Dust Collectors from Quatro stands for Quality! The name PGR stands for what needs to be done in jewelry manufacturing…Polishing, Grinding and Recovery and boasts superior suction in a compact design. Made to fit under/next to most benches, the PGR series is supplied in three (3) unique models to fit all your dust collection needs.

The PGR “IsoFlow” (854-1475, see related item) isolates  your metals in two separate bags allowing you to keep them separate for the refiner.

The PGR “SuperFlow” (854-1479, see related item) is the ultimate model in the series giving you the best suction power and utilizes a variable speed motor to control the suction.

The PGR “MixedFlow” (854-1478) is unique in that it allows you to maximize your filter bag usage since the two-station inlets go into three filter bags.

All the PGR units utilize an intuitive control panel which tells you when to change the filters! Whether you are polishing or grinding, there is a PGR to suit any application! One-year manufacturer's warranty.   Made in Canada.
