According to reports, many dust explosions are started by mechanical sparks. Wet dust collection is seen as a solution to eliminate some of the factors that contribute to dust explosions. Once the dust has been saturated, the level of explosiveness is dramatically reduced. The transfer of the dust from the air into the water removes it from an oxygen rich environment. Without oxygen, combustion cannot occur. The use of water eliminates any potential source of combustion. Since the dust has been eliminated from the air and is now in a dampened state, there is no mechanism by which a dispersed dust cloud can form.

AAF’s line of wet and dry collectors are fully certified and available for use in potentially explosive atmospheres in accordance with the new ATEX Directive 2014/34/EU.

AAF’s products include:

  • RotoClone® W: a highly cost effective and efficient wet dust collector. Combining a dust collector with a centrifugal fan, saving space and enhancing its suitable for a wide variety of different applications. The distinguishing feature of the RotoClone® W is the addition of a fine water film on the impeller blades to capture even the smallest of dust particles.
  • RotoClone® N: combines high efficiency, low maintenance costs, simplicity, flexibility and low water usage to maximize performance. The RotoClone® N is a flexible design for a wide range of operating conditions with minimal servicing requirements. The RotoClone® N is an optimal solution for chemical, industrial processes, metal grinding, and metalworking environments.
  • RotoClone® LVN wet collector: was patterned after the standard RotoClone® N collector, which has been installed in thousands of applications since its introduction in the 1940s. It is efficient, compact and economical and is designed for volumetric flow rates of 2,500 CFM or less.
