Welding fume extractor

CORMAK OS3500

CORMAK OS3500 is a mobile welding fume extractor designed for effective removal of welding fumes and exhaust gases directly at the source. The unit combines high suction power with a large airflow rate, while the sound-insulated fan chamber ensures quiet, smooth operation.

Additional advantages include an integrated pneumatic filter cleaning system, airflow regulation at the suction inlet, and a robust, industrial-grade construction.

Automatic Filter Cleaning – Consistent Performance

The CORMAK OS3500 is designed with user convenience and long-term performance stability in mind. For this reason, it is equipped with an automatic pneumatic filter cleaning system. In practice, this means that accumulated contaminants are regularly knocked off the filter without the need for frequent manual intervention.

The result is twofold: first, the extractor maintains a constant level of efficiency; second, service downtime and operating costs are reduced. In a production environment, this is crucial—any unplanned interruption or loss of suction affects workflow and the quality of working conditions at the workstation.

Adjustable Suction Power Tailored to the Task

Another key advantage is airflow regulation at the suction inlet. This solution allows the extraction force to be adjusted to actual working needs: different for short spot welds, different for long continuous welding, and different again for grinding operations. Regulation at the inlet enables quick, operator-friendly adjustment without time-consuming configuration changes.

This makes it easier to maintain a balance between effective extraction and operator comfort (for example, when working with smaller parts where excessive suction could hinder handling).

Robust Construction and Mobility

The OS3500 is designed for everyday use, which is why great emphasis has been placed on build quality. Its solid construction performs reliably in workshop and industrial environments—where equipment is frequently moved, operates for many hours a day, and must withstand intensive use.

Its mobility allows the extractor to be used at multiple workstations without investing in a permanent installation throughout the entire hall. This is a practical solution for both companies with several workstations and those that frequently change layouts or carry out varied jobs.

Wide Range of Applications

In practice, the OS3500 is suitable wherever air contaminants are generated: welding (MIG/MAG, TIG), metalworking, grinding, and other processes producing dust and fumes. Its purpose is to improve working conditions by reducing pollutants in the operator’s breathing zone. This solution positively impacts employee health, work comfort, and the perception of the facility as a modern and safe workplace.
