Overview and Safety Standards

The TFS-Series 2601 filtration and extraction systems provide triple protection for humans, the environment, and machinery. They comply with stringent safety certifications such as DIN ISO 21904 (W3) and DIN EN 60335-2-69 Annex AA (Dust Class H), effectively filtering fine welding and laser smoke particles and hazardous dusts. Compliance with TRGS 528 is confirmed by IFA, and the units carry W3 and DGUV seals. Dust classification follows DIN EN 60335-2-69 Annex AA, categorizing dust into classes L, M, and H based on hazard level, guiding appropriate system selection to minimize health risks. The systems support adherence to international regulations including TRGS 900 (Germany), OSHA (USA), and others. Stricter German exposure limits for Chromium(VI) and Nickel compounds are noted, alongside EU directives 2004/37/EG and 2022/431 mandating binding workplace limits.

Motor Selection and Application Adaptability

The product range offers multiple motor options tailored to optimize performance based on application-specific factors such as duct length and diameter, particle size, number of extraction points, noise sensitivity, and industrial environment conditions.

Filter Design and Maintenance

The TFS series features a contamination-minimized filter replacement process. The SafeLine filter is enclosed in a sealed casing that remains closed during filter changes, protecting operators from exposure. Heavy particles settle at the filter bottom, preserving filter surface area and extending service life. Filter replacement is tool-free, quick, and performed via the front door. SafeLine and particle filters share a clamping system but can be replaced independently. The activated carbon filter is positioned above saturation filters and is also replaceable separately. Individual filter monitoring enables optimized maintenance and cost control.

Filter Concept and Performance

• Operation with H14 particle filters ensures high safety standards.
• Efficient separation of ultrafine particles.
• Option for cleaned air recirculation.
• Optimized contact time with activated carbon granulate enhances adsorption capacity.
• Activated carbon filters physically adsorb a broad spectrum of gases and odors; custom mixtures are available on request.

Control and Monitoring

Systems include intuitive controls with start/stop buttons, manual power adjustment, and multiple status indicators covering filter saturation, system status, power setting, operating hours, temperature, turbine status, and filter condition. A Sub-D 25 interface allows external control. Advanced electronics provide filter full pre-warning at 75%, collective error outputs (speed, temperature, full filter at 100%), external power regulation, parameter access for special functions, error memory, and digital RS232 interface.

Applications

• Laser Technology: Effective extraction of fine particles from laser marking, engraving, cutting, and welding with W3 certification ensuring occupational safety.
• Automated Welding: Protection against carcinogenic fine particles in processes such as battery cell manufacturing, compliant with TRGS 528.
• Processes with Vapors/Gases: Activated carbon filters remove gases and vapors from adhesives, cleaning, filling, injection molding, and 3D printing, supporting environmental and health protection.
• Dry Dust in Metalworking: Extraction and filtration of chips and particles to maintain clean workspaces and protect workers.

Ordering Information and Accessories

Both TFS500 and TFS1000 models are available in standard and Plus versions, with optional upgrade to dust class H (W3 certification). Replacement filters include SafeLine, particle, activated carbon, and bypass filter mats. Accessories comprise USB cables, remote cable controls, electric foot switches, Harting power connectors, flexible hoses of various diameters and lengths, hose sets, signal modules for volume flow monitoring (mandatory for W3 operation), spark arrestors with ATEX certification, filter break monitoring, volume flow monitoring, and reducers. Spark arrestors can be mounted via magnetic holders or pipe clamps and are available with gravity separators. Some accessories may reduce suction power by up to 10% or 30%, depending on configuration.

Critical Notes and Recommendations

• W3-certified operation requires a signal module with volume flow monitoring or equivalent customer-side functions.
• Filter changes are designed to minimize contamination and operator exposure.
• Strict adherence to national and international exposure limits for hazardous substances is essential, especially for Chromium(VI) and Nickel.
• Custom activated carbon mixtures are available to meet specific application needs.
• Consult TBH sales for tailored motor and filter configurations based on application conditions.
