Description Fans are used in combination with ductwork on KEMPER welding fume exhaust arms, telescopic arms and suction hoses. They are used for LEV or Extraction wherever filtering the air is not important. Due to the cast silumin housing the fan is particularly quiet and spark-proof. The Kemper fans come with various options of motor power and air volumes, and will handle high levels of smoke and particles. They have 100% duty cycle which means they can be run continuously without overheating.
