Tel-Tru 17-023 AC Air Current Detecting Powder Gun

The Tel-Tru 17-023 AC Air Current Detecting Powder Gun is a handheld industrial inspection tool that is AC-powered and uses powder-based airflow visualization to reveal air leaks, trace airflow patterns, and assess pneumatic system performance. It is commonly used in HVAC systems, industrial ventilation equipment, dust collection systems, pneumatic conveying lines, process air systems, and other air-handling applications that require accurate airflow verification. The device supports airflow direction verification and air leak detection through visible powder traces, making it valuable for HVAC commissioning, cleanrooms, ventilation balancing, dust extraction systems, compressed air distribution, and laboratory airflow testing. Maintenance technicians, HVAC service engineers, and industrial system integrators rely on the Tel-Tru 17-023 for preventive maintenance, airflow diagnostics, leak detection, and troubleshooting of industrial air handling systems.
