A problem-solving prefilter for your current dust collection system. Protects workers and equipment from damage and collects dust and valuable precious metal before they reach the dust collector. 

How it works: (1) air, dust and debris enter the swirling vortex inside the Accumulator; (2) dust and debris separate out of air and fall into easy-to-detach Accumulator bowl; (3) cleansed air, now 95% free of dust and debris, flows out of the Accumulator and into your dust collector’s filtering system. 

Installs in your existing system between dust collector and polishing stations. Adapts easily with PVC fittings and can be mounted anywhere along the line. Creates no noticeable drop in suction or dust collector efficiency. Made of durable rotationally molded low density polyethylene. 

Available in three sizes: Small for 1 station, Medium for 1–2 stations and Large for 1–4 stations. Made in USA.
