Robotic Weld Cells Air Change Rate - 06/27/2025

For a robotic Weld cell, the recommended air changes per hour (ACH) for fume extraction typically range from 10 to 20 ACH, depending on factors like the welding process, materials, fume generation rate, & local regulations. Micro Air suggests you get in contact with your local distributor to help work through the variables.

• Mild steel welding with moderate fume production may require 10-15 ACH
• Stainless steel or aluminum welding, which produces more hazardous fumes (ex, hexavalent chromium or ozone), often needs 15-20 ACH or HIGHER.
• High-intensity processes like plasma cutting or heavy-duty welding may demand even greater ventilation
• ASHRAE standards for industrial ventilation suggest custom tailoring to each application.
