VF-W ATEX Series
ATEX Universal Worm Gear Units
Some industrial environments are characterized by the presence of explosive atmospheres and thus require additional safety measures. Industrial equipment operating in such conditions must be specifically designed to prevent ignition of the flammable substances present in the atmosphere. To meet our customers’ needs, Bonfiglioli has developed an entire line of gearboxes that can be safely used in explosive environments in accordance with ATEX Directive 201/34/EU. If the ATEX version is selected, gearboxes of VF/W, ACF, HD and 300M Series will be manufactured for the utilization in zones 2G/2D and 3G/3D.
