Product Reclamation
In an age of rising costs and environmental concerns, even small efforts to decrease volumes of unsalvageable product can help ease operational costs and protect the environment. Installing cyclone pre-filters before baghouses and cartridge collectors is one such method of product reclamation; they help prevent product contamination by the filters themselves and other materials present on the filters by capturing and separating material otherwise lost to fabric filters. Prefilters can be installed at the direct location of dust generation or ahead of downstream filters to capture 80-90% of particulate. Those installed near the location of dust generation tend to provide the least contaminated material, while cyclones located right before the filter risk ductwork and other airstreams introducing possible contamination. 
Cyclones are well-suited to capture dusts for:
- Precious metals (gold, silver, etc.)
- Pharmaceuticals and Food processing
- Raw materials
- Selling of reclaimed waste products
A ceramics manufacturer in Pennsylvania would ship a semi load of waste to the dump a month. They would lose the cost of the raw material, the shipping, and the disposal fee. The material couldn’t be reused because it was collected in a baghouse from their dryer. The baghouse would have various products raw materials in the filters, so when it was collected it was contaminated.
Aerodyne offered them a compact GPC cyclone to use as a prefilter. The cyclone was fitted with Vacu-Valve airlock to allow the material to leave the cyclone without additional air entering the system. After installation, they have been able to minimize the disposal of raw materials. They have been able to reuse the material from the cyclone, thereby saving thousands of dollars a month while also paying for the cyclone very quickly. Besides the money they are saving, they also can take pride in the knowledge that they have minimized their effect on the environment by increasing their recycling of raw materials.
