Impellers

for duct fans

Main advantages

Impellers are backward curved and are highly reliable, energy efficient and long-life. They are capable to work under increased loads for over 30,000 hours.

All impellers are equipped with thermal contacts with automatic restart. If the engine is overheated, the fan will turn off and automatically turn on after cooling down.

Operating variables of impeller can be set in 2 ways: by using phase regulators or transformer voltage regulators.

Important characteristics

  • Mean lifetime is over 30 000 hours
  • Backward bent blades
  • Single-phase motors
  • Automatic restart when the engine overheats
  • Voltage 1~220 V / 50 hz
