Tough Dusts

Baghouses and cartridge collectors are often used for dust collection. However, not all dust is the same. Some dust causes issues with the filters in baghouses and cartridge collectors. Aerodyne calls this “Tough Dust”.  The tough dust can be:

1. Abrasive – wears our filters and housings 
   1. SplitStream Cyclone
   2. GPC cyclone
2. Hygroscopic – plugs up filters
   1. SplitStream Cyclone
   2. GPC cyclone
3. Wet and/or sticky – degrades and plugs up filters
   1. GPC cyclone
   2. SplitStream Cyclone
4. Friable – can be damaged by dust collection
   1. SplitStream Cyclone

Cyclone pre-filters can often help with these applications. The cyclone pre-filter removes the larger dusts (oftentimes as much 80-90% of the dust). This lessens the impact of the dust on the filters. And since cyclones don’t have any moving parts, the maintenance on them is very easy (periodic inspection for holes).
