Our motors also meet CE standards and fulll the international specications of approved institutes such as CSA and UL. They are produced in accordance with IP55 standard (dust and water resistant) and the materials used meet the standard of insulation class F (resistance to temperatures up to 155°C / 311°F). Advantages • • • • Low energy consumption Construction Class F motor (155°C / 311°F) Tubes are UV-resistant, corrosion proof and light-weighted Tubes in colours RAL 7011 (Iron Grey), RAL 7032 (Pebble Grey) RAL 7033 (Cement Grey), RAL 7035 (Light grey) • • • • • Low level of maintenance and long life cycle Built-in thermal protector Water resistant (IP55) Low noise level 3 year warranty on fans
