Application
1. Exhaust ventilation systems for commercial, office and other public or industrial premises for extraction of air with temperatures up to 55°С.
2. Direct air exhaust is provided.
Design
1. Steel casing with polymeric coating ensures motor protection against direct humidity exposure in case of the unit outdoor mounting.
2. The fan bottom has a bird and rodent proof guard.
3. Air is exhausted vertically down.
Mounting
1. The fan is designed for outdoor surface wall mounting and connection to round duct of the respective diameter.
2. The fan is powered through the external terminals.
3. Electric connection and mounting shall be performed in compliance with the manual and wiring diagram provided in unit operation manual.
Motor
1. The centrifugal impeller with backward curved blades is powered by the single-phase motor with external rotor and overheating protection with automatic restart.
2. The motor is equipped with ball bearings for long service life designed for at least 40 000 hours.
3. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
4. Motor protection rating IP 44.
Speed Control
1. Smooth or step speed control with a thyristor or autotransformer speed controller.
2. Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.
