Clean Air During Casting Fettling Protects Personnel

After blasting, cast parts are separated from risers and feeders. Fine metal oxide dust generated during angle grinding, sawing, or cutting must be thoroughly extracted to ensure a safe and clean work environment.

For larger castings, flame cutting is often used, which requires a high-volume air supply. The associated filter units are conservatively designed to handle very fine dust particles effectively. When processing non-ferrous metals, appropriate explosion protection measures must be in place if dust collectors are used.

 

 

Flexible Extraction Solutions for All Materials

For ferrous metals, dust extraction is effectively handled using a VARIO dust collector equipped with KLR filters. This setup delivers high separation efficiency and supports clean air recirculation, making it highly energy-efficient.

When working with non-ferrous metals, wet separators are typically used. These systems operate at lower air volumes, resulting in reduced upfront investment. While dust collectors offer lower long-term operating costs, they require appropriate explosion protection measures when used with combustible non-ferrous metal dusts.
