Welding filters play a crucial role in ensuring the air quality for workers. These filters are not just accessories; they are vital components that trap and remove harmful particles generated during welding. These filters help prevent hazardous fumes and particulates from being released into the atmosphere, protecting the environment and the health of individuals working near welding operations. By capturing these contaminants, filters contribute to creating a cleaner and healthier workspace. In this blog, we will explore the types of welding filters used.


Common Types of Filters Used in Welding Fume Extraction Systems


1. Pre-filter:

The pre-filter plays a crucial role in capturing larger particles and debris before they reach the main filter. Think of it as the first line of defence against harmful fumes and contaminants in the air. The pre-filter is designed to target bigger particles that could clog or damage the main filter if not caught beforehand. By trapping these large particles early on, the pre-filter helps extend the lifespan and efficiency of the entire filtration system.


2. Main filter:

The main filter traps smaller particulates that may have passed through the pre-filter, ensuring cleaner air output. Main filters are typically made of high-efficiency materials like HEPA or activated carbon, capable of catching even the tiniest particles produced during welding processes. By using advanced filtration technology, these filters help maintain a safe and healthy work environment for welders and surrounding personnel.


3. After filter:

As the final line of defence in welding fume extraction systems, after filters play a crucial role in ensuring that only clean air is released back into the environment. By trapping any remaining particles and contaminants (approximately 0.1 to 0.3 microns), after filters help maintain a safe and healthy work environment for welders.
