Welding Extraction Unit, Welding Fume Extractor CORMAK OS3500

Healthier and safer working environment

Welding fumes are not only an unpleasant smell and poorer visibility. Above all, they are a mixture of very fine particles and compounds which, in enclosed halls, can quickly worsen working conditions. The OS3500 was created to capture fumes and smoke where they are generated, before they spread around the workstation and throughout the hall. This allows the operator to work in a cleaner environment, while making it easier to maintain occupational health and safety standards and order at workstations in the facility.

High performance in demanding conditions

The key advantage of the OS3500 is the combination of high suction power with high air flow (m³/h). In practice, this means stable and effective extraction of contaminants even when work is intensive and there is a large amount of smoke, for example during continuous welding, joining thicker elements or longer weld penetrations. High performance helps reduce smoke escaping around the working area and improves visibility, which directly translates into work quality and welder comfort.

Quiet operation – greater comfort at the workstation

The high operating culture of the unit is also of great importance in everyday use. The OS3500 is equipped with a sound-insulated fan chamber, which reduces noise and allows the unit to operate close to the welding workstation. This is particularly important in workshops and halls where several workstations operate at the same time and every additional noise matters. Quieter operation makes communication at the workstation easier, improves operator concentration and genuinely increases comfort throughout the entire shift.

Automatic filter cleaning – constant performance

In the CORMAK OS3500, emphasis has also been placed on operating convenience and stable performance over time. For this reason, an automatic pneumatic filter cleaning system has been used. In practice, this means that the filter is regularly “pulsed” to remove accumulated contaminants without the need for frequent manual intervention in the unit.

The effect is twofold: firstly — the extractor maintains performance at a constant level, and secondly — you reduce service breaks and operating costs. In a production environment, this is extremely important, because every unplanned stoppage and drop in suction affects the work rhythm and the quality of conditions at the workstation.

Extraction power adjustment matched to the work

An additional advantage is the adjustment of fume and smoke flow at the suction connection. This solution allows the extraction power to be matched to actual needs: it will be different for short spot welds, different for long continuous welding, and different again for grinding work. Adjustment at the connection provides quick “operator-specific” setting without time-consuming configuration changes.

This makes it easier to maintain a balance between extraction effectiveness and working comfort, for example with smaller workpieces where overly aggressive suction could make handling the component more difficult.

Robust construction and mobility

The OS3500 is equipment for everyday use, which is why great emphasis has been placed on high-quality workmanship. The robust construction performs well in workshop and industrial conditions — where units are moved, work for many hours a day and must withstand intensive use.

Mobility makes it easier to use the extractor at different workstations without investing in a fixed installation throughout the entire hall. This is a practical solution both for companies with several workstations and for those that frequently change their work layout or carry out different orders.

Wide range of applications

In practice, the OS3500 will perform well wherever airborne contaminants are generated: during welding (MIG/MAG, TIG), metalworking, grinding and other processes that generate dust and smoke. Its task is to improve working conditions by reducing contaminants in the operator’s breathing zone. This solution affects the health of the team, working comfort and also the perception of the facility as a modern and safe workplace.
