CORMAK OS3500 is a mobile welding fume extractor designed to effectively remove fumes and gases directly at the source. The unit combines strong suction power with high airflow, while its sound-insulated fan chamber ensures quieter operation. Additional advantages include an integrated pneumatic filter cleaning system, airflow adjustment at the suction inlet and robust industrial construction.
Welding fumes are not just about unpleasant odours and reduced visibility. Above all, they are a mixture of very fine particles and compounds that can quickly deteriorate working conditions in enclosed industrial halls. The OS3500 was developed to capture fumes and gases directly where they are generated, before they spread across the workstation and throughout the entire production hall. This allows operators to work in a cleaner environment while making it easier to maintain occupational health and safety standards and keep workstations tidy.
A key advantage of the OS3500 is its combination of strong suction power and high airflow (m3/h). In practice, this ensures stable and effective extraction of contaminants even during intensive operations involving large amounts of welding fumes (e.g. continuous welding, joining thicker components or prolonged welding passes). High extraction performance helps prevent fumes from escaping into the surrounding work area and improves visibility, directly contributing to work quality and welder comfort.
Another important factor in everyday use is the unit's smooth and quiet operation. The OS3500 is equipped with a sound-insulated fan chamber, which reduces noise and allows the extractor to operate close to the welding workstation. This is particularly important in workshops and industrial halls where several workstations operate simultaneously and every additional source of noise matters. Quieter operation makes communication easier, improves operator concentration and significantly increases comfort throughout the working shift.
The CORMAK OS3500 is also designed for ease of operation and consistent performance over time. For this reason, it features an automatic pneumatic filter cleaning system. In practice, this means that accumulated contaminants are regularly dislodged from the filter without the need for frequent manual intervention.
This provides two benefits: firstly, the extractor maintains a consistent level of performance; secondly, it helps reduce maintenance interruptions and operating costs. This is particularly important in production environments, where every unplanned stoppage or reduction in suction power affects workflow and the quality of working conditions at the workstation.
Another advantage is the ability to adjust the extraction airflow for fumes and gases directly at the suction inlet. This allows the extraction power to be adapted to actual requirements: short spot welds require different suction levels from prolonged continuous welding, while grinding operations may require different settings again. Adjustment at the suction inlet enables quick, operator-specific settings without time-consuming configuration changes.
This makes it easier to maintain the right balance between extraction efficiency and working comfort (e.g. when handling smaller components, where excessive suction could make positioning and manipulating the workpiece more difficult).
The OS3500 is designed for everyday use, with particular emphasis on high-quality construction. Its robust design is suitable for workshop and industrial environments where equipment is frequently repositioned, operates for many hours each day and must withstand intensive use.
Its mobility makes it easy to use the extractor at different workstations without investing in a permanent extraction system throughout the entire production hall. This is a practical solution both for companies with several workstations and for businesses that frequently change their production layout or undertake different types of work.
In practice, the OS3500 is suitable wherever airborne contaminants are generated, including welding (MIG/MAG, TIG), metalworking, grinding and other processes that produce dust and fumes. Its purpose is to improve working conditions by reducing contaminants in the operator's breathing zone. This solution contributes to employee health, working comfort and the overall perception of the facility as a modern and safe workplace.
