Winter brings a unique challenge for welding shops and metal fabricators, how to maintain adequate fume extraction while keeping the workspace warm. It’s a delicate balance between safety and comfort, especially in enclosed or semi-insulated workshops where every degree matters.

At Fanmaster, we specialise in helping industrial environments maintain clean, compliant air quality while optimising energy use. In this blog, we break down key strategies for winter ventilation for welding shops.

The Ventilation Challenge in Winter

Welding, cutting, and grinding produce hazardous fumes that must be extracted to meet OH&S standards and protect worker health. However, standard extraction methods, like opening roller doors or running high-capacity exhaust fans, often lead to substantial heat loss.

This creates:

  • Cold drafts in the workshop
  • Increased energy costs as heaters work harder
  • Reduced comfort and productivity for welders

Smart Ventilation Solutions for Cold Weather

To avoid compromising on either air quality or temperature, consider the following:

  1. Localised Fume Extraction

Using portable fume extractors or wall-mounted arms, you can target welding fumes right at the source. These systems reduce the need for full-space air turnover, preserving more warmth inside.

  1. Centrifugal Roof Fans with Speed Control

These roof-mounted fans are ideal for workshops needing continuous fume removal. When fitted with variable speed drives, they can be adjusted to run at lower speeds during winter, reducing heat loss while still maintaining air quality.

  1. Cross Flow Ventilation

Instead of fully opening doors, install wall louvres or roof vents that allow air to enter and exit in a controlled flow. This maintains air circulation while minimising thermal loss.

  1. Zoned Heating

If extraction is required in just one area, use portable heaters to warm the zone where staff are working, rather than the whole space.

Recommended Fanmaster Products for Weld Shops

  • Fume Extractors: Compact, flexible-arm models ideal for welding bays
  • Centrifugal Roof Fans: High performance for large metal workshops
  • Wall Louvred Exhaust Fans: Great for creating passive airflow in cross-ventilation setups
  • Gas Radiant Heaters: Efficient heating without disturbing airflows

Final Tips for Balancing Safety and Warmth

  • Regularly inspect your extraction systems, clogged filters or sluggish motors reduce efficiency
  • Schedule heavier welding tasks earlier in the day when indoor temperatures are more stable
  • Use curtains or screens to isolate welding zones and retain heat
