| DESIGN | MOTOR | |
|
The fan casing is made of galvanized sheet steel using heat- and sound-insulation material.The round connecting spigots are rubber sealed.The hinged cover gives free access to the motors, simplifies installation and maintenance of the fans and ducts without dismantling.The air damper allows adjusting the direction of air flow. Controlled by the air flow.  |
The unit is equipped with high-efficient electronically commutated (EC) DC motors with mixed-type impellers.These state-of-the-art motors are the most advanced solution in energy efficiency today.The motors are equipped with built-in overheating protection.Ball bearings in the motor ensure long service life (40 000 hours).To achieve accurate performance, low noise levels and safe fan operation, each turbine is dynamically balanced during assembly.The motor ingress protection rating is IP44. |

| CONTROLLER | MOUNTING | |
|
Allows tracking the motor failures and signalling them, as well as automatically switching the unit to operation with a functioning motor.The controller is not included in the delivery set and must be ordered separately. |
The duct fans are intended for mounting to round air ducts.The fans are installed between the air ducts.While mounting the fan provide enough access for servicing and repair operations.  |
|
| OPERATION MODES: | ||
|
Automatic alternation of the active fan with preset switching period.Forced constant operation of the fan A. Forced constant operation of the fan B. Fan alarm. The failed fan is switched off, the second fan is switched on. The controller generates an error signal and corresponding indication.Fan speed control.Boost mode increases the performance of the fan. It is possible to set the time during which the fan will run in this mode.Test mode. Automatic alternation of the active fan with a period from 1 to 12 min.Checking motors at start-up.Possibility of connection to BMS.Possibility of connecting an external 0-10 V sensor. Possibility of connecting external devices (10 V and 24 V). |
