Single arm and double arm welding smoke purifiers each have their own advantages and disadvantages. At the rated processing air volume, the smoke removal rate is ≥ 99%. The clean air discharged after treatment can be directly circulated and discharged in the workshop. The choice of which is better depends on the specific usage scenario and needs. ‌

Single arm welding smoke purifier
The single arm welding smoke purifier is suitable for small-scale or single welding point working environments. It is suitable for use in small repair workshops or individual welding stations and has the following advantages:

Low cost: Single arm purifiers typically have lower costs and are suitable for users with limited budgets.
Easy to operate: Due to its relatively simple structure, it is also more convenient to operate and maintain.
Suitable for small spaces: Suitable for places with limited workspace or compact layout.

Dual arm welding smoke purifier
The dual arm welding smoke purifier is suitable for environments where large-scale or multiple welding points are working simultaneously. It is suitable for large manufacturing factories or multiple welding stations and has the following advantages:

Wide coverage: The dual arm design can effectively cover a larger work area, suitable for continuous welding operations or situations where multiple welding points need to be processed simultaneously.
High flexibility: If the workplace is spacious and the layout allows for a larger range of equipment movement, the dual arm dust collector can adjust its position and coverage more flexibly.

The single arm welding smoke machine requires one worker to perform welding operations, while the dual arm welding smoke dust collector requires two workers to perform welding operations simultaneously. But this has a prerequisite requirement:

1) If dual arm welding smoke dust removal is required, there are requirements for the working time distance between two workers, and it is generally recommended to have a distance of about three meters.

2) If there are a large number of welding workers in the workshop and they meet the upper spacing conditions, it is recommended to use a dual arm welding smoke dust collector. This can save a lot of space and, compared to the two, one arm can support two single arms.
