Air - Flow Marker (Pack of 5) - Safety Signs by Caledonia Signs

Air – Flow Markers are important because they clearly indicate the direction of airflow within compressed air or ventilation systems. Proper identification helps maintenance teams, engineers, and operators manage airflow safely and efficiently, preventing errors that could affect system performance or safety.

These markers prevent confusion between air lines and other types of piping, ensuring correct valve operation, system balancing, and maintenance procedures. Knowing the flow direction supports troubleshooting, reduces downtime, and helps avoid damage to equipment like compressors, filters, and pneumatic tools.

Air flow markers are typically used on compressed air pipes, ventilation ducts, pneumatic control systems, and air distribution networks in industrial plants, commercial buildings, and manufacturing facilities.

By providing clear visual cues, air flow markers improve safety, operational efficiency, and help ensure compliance with industry standards and regulations related to air handling systems.
