Enclosures made of fire-resistant plastic resin, class E2, according to ISO EN 11925-2: 2010, in areas near engine and electrical components.
Housing incorporating a sound-absorbing coating, optimized to minimize sound emissions emitted into the environment and transmitted through the exhaust and supply ducts.
Nominal diameter 250 mm.
EC motor (brushless), thermally protected, with shaft mounted on bearing supports, combined with a centrifugal impeller.
High water resistance: IPX5 (if installed in a duct).
Equipped with thermal safety overheat safety device.
Adjustable speed via potentiometer (0-10V signal) or two-speed switch (to be set at the installation in a predetermined range).
