Rotating Brush Generator (RBG) Series
Low and medium dose rate

CH Technologies RBG Series has been used in more applications than any other solid powder generator we offer. Its ease of use has resulted in a popularity that spans a broad range of industries with concerns that include mineral dusts, medical compounds, and pollen to name a few.

Initially designed for the filter industry, the RBG Series, over 20 years, has been adapted to the pharmaceutical and chemical industry with great success. It is one of the most consistent powder dispersers available today. Its extraordinary consistency serves needs equally well across a level of demands that range from delivering very low flows of a precious material to higher flows of dust required by a filter testing procedure.

CH Technologies offers the RBG in different variations and setups for a multitude of different circumstances so please inquire about the range of possibilities made capable with the various RBG models.
