The devices of the EXT series are centrifugal vacuum cleaners and as such are able to overcome the aeraulic resistance of long ducts. The air sucked in must not be dusty or corrosive.

Features:

• Centrifugal duct fans for outdoor installation
• Suitable for clean air with temperature from -20° to 60°C
• They avoid the installation of traditional and bulky vacuum cleaners inside the rooms, keeping their aesthetics unchanged.
• The outdoor installation solves any problem related to the noise of the vacuum cleaner in the rooms to be ventilated.
• They prevent the return of air when the appliance is switched off, therefore they are particularly suitable in windy areas.
