ProtectONE® T range
  • ProtectONE® T is a range of smoke and heat exhaust fans with belt and pulley drive.

  • Two models depending on the impeller (forward curve or backward curve):
  • ProtectONE® TA (forward curve impeller), 9 unit sizes offering airflow rates from 1,000 to 40,000 m³/h,

    ProtectONE® TR (backward curve impeller), 8 unit sizes offering airflow rates from 1,000 to 35,000 m³/h. This enables better results due to lower airflow variation when the load varies.
