Ever greater emphasis on in-plant hygiene and Best Manufacturing Practice places creates a need for specialist products to serve this sector. Growing use of sophisticated and expensive ingredients such as Stevia means there is a requirement for constant flow dust extraction systems. This because after and super accurate weigh heads have been set up there must be no variation if air extraction flow to disturb the calibration.  Unlike pulse jet filters where uniform flow cannot be guaranteed the AAF RotoClone W runs for extended periods with constant uniform performance. Because all the dusts are soluble the use of the RotoClone W compact wet scrubber is highly advantageous. It’s inherent safety (ATEX compliant) is of real advantage and it’s quiet running and compact dimensions often make the RotoClone W the automatic choice for this industry.
