Compressed Air in Foundries and Casting Operations

Compressed air is vital in metal casting, from efficiently applying mold release and compacting sand in molds to effectively cooling castings and cleaning finished pieces. However, foundry conditions—dust, heat, and abrasives—strain air systems, and poor air quality can cause mold defects, tool wear, and downtime. A well-maintained system with clean, dry air ensures reliable pneumatic tool performance, consistent casting quality, and reduces the need for rework. Furthermore, optimizing your system's efficiency, perhaps through technologies like variable speed drives or energy recovery, can lead to substantial energy savings, a significant factor given the high air demands of many casting processes.

Foundries

With their combination of high heat and insidious airborne particulate, foundries are notoriously bad environments for compressors. Kaeser’s full cabinet and smart airflow design helps keep out contaminants for longer, more reliable operation. And generously sized coolers keep our units going when others can no longer take the heat. But sometimes, even that is not enough. Kaeser’s custom engineering capabilities offer different approaches to dealing with poor compressor room conditions

Kaeser compressed air products for the metal casting industry

• Rotary screw compressors: Available from 3 to 700 hp, these packages are capable of handling demanding conditions.
• Compressed air treatment products: Dirt, oil, and other impurities enter the compressor with atmospheric air and during the compression process. If not removed, these contaminants may cause costly production problems including equipment contamination and accelerated tool wear. KAESER offers a complete line of air treatment products including dryers, filters, and drains to prepare compressed air for even the harshest environments.
• Breathing air systems for contaminant removal: The Kaeser Breathing Air System (KBS) is designed to remove contaminants such as moisture, solid particles, oil or oil vapors, carbon monoxide and hydrocarbons from normal compressed air.
