About the Puma DEX

Grain terminals, feed mills, sugar and starch plants, and metal powder handling all produce combustible dust in quantities a small vacuum cannot keep up with. The Puma DEX is the certified machine for that scale of work, and can also power a fixed pipework system with several suction points inside the zone.

A 100 mm tangential inlet and cyclone drop the bulk of the material into the 175 litre stainless bin. The air then passes a 45,000 cm² antistatic filter and, on the 1/2D version, an H14 absolute filter. Larger Puma 30 DEX models are available on request.
