Kondisi: baru, Tahun pembuatan: 2026, CORMAK OS2400 is a mobile welding fume extractor designed for effective removal of fumes and exhaust gases directly at the source. The unit combines high suction power with a substantial airflow rate, and thanks to its sound-insulated fan chamber, it operates with minimal noise levels, ensuring workplace comfort. Notable features include an integrated pneumatic filter cleaning system, airflow adjustment at the suction nozzle, and a robust, industrial-grade construction. Automatic Filter Cleaning – Consistent Performance The CORMAK OS2400 is engineered for user convenience and stable long-term performance. It is equipped with an automatic pneumatic filter cleaning system. In practice, this means the filter is periodically cleaned from accumulated contaminants without frequent manual intervention. Gsdpoyguclefx Aa Deud The benefits are twofold: firstly, the extractor maintains consistent performance; secondly, it reduces service interruptions and operating costs. In manufacturing environments, this is crucial—any unplanned downtime or loss of extraction power disrupts workflow and compromises workstation conditions. Adjustable Extraction Power – Tailored to Operations Another advantage is the adjustable fume and gas flow at the suction nozzle. This feature allows you to tailor the extraction strength to your actual needs: one setting for short spot welds, another for long continuous welding, and yet another for grinding tasks. Adjustment at the nozzle enables quick, operator-specific settings without time-consuming reconfiguration. This flexibility helps maintain a balance between effective extraction and work comfort (for example, when handling small parts, overly powerful suction could hinder element manipulation). Sturdy Construction and Mobility The OS2400 is designed for daily use, emphasizing high build quality. Its solid construction excels in workshop and industrial environments—where equipment is regularly repositioned, used for many hours per day, and subjected to heavy-duty operation. Its mobility makes it possible to use the extractor at various workstations without the need for a permanent installation across the facility. This is a practical solution for companies with multiple stations as well as those frequently changing their setup or handling diverse tasks. Versatile Applications In practice, the OS2400 is suitable wherever airborne contaminants are generated: welding (MIG/MAG, TIG), metalworking, grinding, and other processes that produce dust and fumes. Its primary function is to improve workplace safety by reducing pollutants in the operator’s breathing zone. This benefits team health, work comfort, and the overall perception of the facility as modern and safe. Technical Specifications | Model | Airflow (m³/h) | Pressure (Pa) | Filter Efficiency (%) | Power (kW) | Voltage (V) | Weight (kg) | |-----|-----|-----|----- |-----|-----|-----| | OS2400 | 2,400 | 2,000 | 99.9 | 2.2 | 400 | 80 | | OS3500 | 3,500 | 2,000 | 99.9 | 3 | 400 | 122 | *Note: The set does not include a power cord or plug, due to diverse connection infrastructures and customer requirements.

Kondisi: baru, Tahun pembuatan: 2026, CORMAK OS3500 is a mobile welding fume extractor designed for efficient removal of smoke and exhaust gases directly at the source. The device combines strong suction power with a high airflow rate, while the sound-insulated fan chamber ensures particularly quiet operation. Key advantages include the integrated pneumatic filter cleaning system, adjustable airflow at the suction inlet, and a robust, industrial-grade design. Automatic Filter Cleaning – Consistent Performance The CORMAK OS3500 also prioritizes ease of use and stable performance over time. That’s why it features an automatic pneumatic filter cleaning system. In practice, this means the filter is regularly cleaned of accumulated contaminants without the need for frequent manual intervention. This provides two main benefits: firstly, the extractor maintains its performance at a constant level; secondly, service interruptions and operating costs are minimized. In a production environment, this is highly important, as any unplanned downtime or drop in extraction efficiency directly impacts workflow and the quality of workplace conditions. Extraction Power Adjustment Tailored to Tasks Another advantage is the airflow adjustment at the suction nozzle. This allows you to set the extraction force to match actual work requirements: settings differ for short spot welds, long continuous welding, or grinding operations. Adjustment directly at the nozzle gives operators quick, personalized control without the need for time-consuming reconfiguration. As a result, it’s easier to balance extraction efficiency with operator comfort (e.g., when working with small parts where excessive suction could make handling difficult). Robust Construction and Mobility The OS3500 is built for everyday use, with a strong emphasis on high manufacturing quality. The solid construction is ideal for workshop and industrial environments—where equipment is often relocated, operates for many hours daily, and must withstand intensive use. Gujdpfx Aaeygt Utj Djd Mobility ensures the extractor can be used at various workstations without investing in a permanent installation throughout the entire hall. This is a practical solution for companies with multiple stations, as well as those that frequently change workflows or handle diverse tasks. Versatile Applications In practice, the OS3500 is suitable wherever air contamination is generated: during welding (MIG/MAG, TIG), metalworking, grinding, and other dust- and fume-producing processes. Its purpose is to improve working conditions by reducing airborne contaminants in the operator’s breathing zone. This solution benefits team health, working comfort, and enhances the facility’s reputation as a modern, safe workplace.
