9-3498 - Thermal Dynamics 16-Inch Replacement Fan Blade for Plasma Cutters

Thermal Dynamics 9-3498 Fan Blade Overview

The Thermal Dynamics 9-3498 is a specialized replacement fan blade designed for specific high-performance plasma cutting power sources. As a critical component of the machine's thermal management system, this fan blade is engineered to move a substantial volume of air across internal heat sinks and electronic components. With a diameter of 16 inches, it provides the necessary static pressure and airflow required to maintain the equipment's rated duty cycle, particularly during extended cutting operations or in environments with high ambient temperatures.

Manufactured to strict OEM specifications, this fan blade ensures correct balance and fitment. Using non-OEM or generic fan blades in precision welding and cutting equipment can lead to vibration issues, increased noise levels, and inadequate cooling, potentially voiding warranties or causing premature failure of power transistors. The 9-3498 is constructed from durable materials capable of withstanding the thermal cycling and mechanical stresses typical of industrial workshop environments.

Proper cooling is paramount for the longevity of inverter-based and transformer-based power supplies. If the original fan blade has become cracked, unbalanced, or damaged due to debris ingestion, immediate replacement is recommended to avoid thermal overload errors. This part is supplied as the blade unit only; mounting hardware and the fan motor are typically sold separately or reused from the existing assembly. Verify compatibility with your specific Thermal Dynamics or ESAB model service manual before installation.
