TFV 900 Ex Centrifugal Fan<\/h2>\n

\"Centrifugal<\/a><\/p>\n

<\/div>\n

Proper ventilation is not only important for a pleasant working environment, but is also essential in many areas for occupational safety reasons and in accordance with official regulations.<\/p>\n

Ventilating rooms removes harmful substances such as paint and varnish fumes, welding fumes, dust particles, carbon monoxide, nitrogen oxides, carbon dioxide, and water vapor.<\/p>\n

Whether it involves large-scale ventilation of duct and pipe systems in Class 2 explosion-protected zones, the cleaning of cargo ship tanks, or construction work at refineries \u2014the TFV 900 EX high-pressure centrifugal fan, designed in accordance with the ATEX Directive 2014\/34\/EU, is ideally equipped for such tasks, as it delivers up to 25,000 m\u00b3\/h of air, even through connected air transport hoses, over very long distances with high back pressure, and is designed to be extremely stable in harsh operating environments. <\/p>\n

Harsh environments do not affect this high-quality unit, as the centrifugal fan is integrated into a sturdy powder-coated steel housing with a highly durable two-component paint finish. All desired steel grades are available upon request. <\/p>\n

In addition to the standard frameless version, the TFV 900 Ex is also available in the configuration shown in the illustration, which includes an additional galvanized steel frame with sturdy transport rollers, forklift slots, and crane lifting points. The transport frame offers you maximum mobility and is ideal for use in frequently changing locations. <\/p>\n

TFV 900 Ex switches, cables, and plugs are approved for use in potentially explosive atmospheres. Suitable connectors, approved for use in Zones 1, 2, 21, and 22, are available for extension cables. <\/p>\n

An 18.5 kW star-delta contactor combination for the TFV 900 Ex is also available as an option for EX Zone 22, 400 V, AC3, IP 55.<\/p>\n

Here are a few of the practical advantages of the TFV 900 Ex, in brief:<\/strong><\/p>\n

    \n
  • Development, design, manufacturing: 100% Trotec<\/li>\n
  • Explosion Protection Group II, Category 3G, Temperature Class 4<\/li>\n
  • A robust, high-current, high-quality device “made in Germany.”<\/li>\n
  • Splash-proof version (IP55)<\/li>\n
  • The fan motor is located outside the main airflow<\/li>\n
  • Can be connected to both intake and exhaust ducts<\/li>\n
  • Stable regions on the characteristic curve and consistently high pressure<\/li>\n
  • Also available optionally for Explosion Protection Group II, Category 2G (Zone 1), Category 2D (Zone 21), and Category 3D (Zone 2).<\/li>\n<\/ul>\n

    Explosion protection refers to protection against explosions and their effects. Its purpose is to prevent damage caused by systems, technical products, and the like. Explosion protection encompasses legal provisions such as the European Union\u2019s ATEX directives. Important: Please ask our service staff about the use of explosion-proof fans! <\/em><\/strong><\/p>\n
