FANS WITH BRUSHLESS TYPE EC MOTOR
The fans electric motors are the brushless type with built-in electronic commutation system (EC) which yield high energy savings during operation in reduced air flow.
These electric motors are ensuring high performances, minimum energy
consumption and total absence of electromagnetic noise.

INDOOR INSTALLATION
The machines are designed for indoor installation and ducting for air suction and discharge.
For outdoor installation the use of the dedicated optional kit is mandatory The machine must be installed under a cover or anyway protected agains atmospherics agent.
