3 GD Fans<\/h2>\n\n\n\n

Must necessarily have<\/strong>:<\/strong><\/p>\n\n\n\n

    \n
  • inspection hatch to check for any dust build-up inside the drum and that the necessary gaps between moving and stationary parts are maintained;<\/li>\n\n\n\n
  • suitable gaskets designed to prevent excessive fluid leakage from the flanges;<\/li>\n\n\n\n
  • protective nets for suction and discharge*;<\/li>\n\n\n\n
  • motor suitable for the zone where it is used.<\/li>\n<\/ul>\n\n\n\n

    Impellers can be made of aluminium or glass fibre reinforced polyamide<\/strong>:<\/strong><\/p>\n\n\n\n

      \n
    1. aluminium with aluminium drum or carbon steel drum with riveted brass band, usable up to 245\u00b0C;<\/li>\n\n\n\n
    2. glass fibre reinforced polyamide with carbon steel drum usable up to 110\u00b0C, for sizes up to 450 with 2-pole motors, up to 900 with 4-pole motors.<\/li>\n<\/ol>\n\n\n\n

      (*) The Atex directive and CE marking require compliance with the machinery directive, so the Atex fan, at the regulatory level, must be considered as a quasi-machine and therefore protected. A user who, after careful risk analysis, considers it advisable to remove the protections should still leave them with the fan in anticipation of using the fan for something else.<\/p>\n\n\n\n

      2 GD Fans<\/h2>\n\n\n\n

      Exactly what was said about the 3 GD model applies, in addition the motor must be suitable for the different zone where it is used.<\/p>\n","protected":false},"excerpt":{"rendered":"
