BOX-D

Direct drive double inlet box fans

General Description
The fan of the BOX-D series are particularly designed for air extraction, supply or filtration.
Their main characteristic is the low noise level which makes them ideal for urban environ-
ments (apartments, houses, bard restaurants, gymnasiums, offices) and industrial sites
where radiated noise is a problem. The low noise level is due to their plenum lined with
acoustic material, that allows a remarkable reduction of noise level, inevitably generated
by the fan. The blower consists of a double inlet forward curve centrifugal fan with built-in
motor.

Construction
• Profiless cabinet is manufactured in PPGI sheet with removable access panel to allow
easy access to fan and motor.
• The blower is fitted using suitable support feet and is completely isolated from the ca
sing by anti-vibration mounts and gaskets.
• Acoustic lining in self-extinguishing techno-polymer
• Double inlet blower, forward curved, with direct drive built-in asynchronous motor, sin
gle-phase or three-phase, particularly suitable for speed regulation (using the suitable
speed regulators shown in this catalogue).
• Flanged Inlet and outlet for easy Duct Work

Upon request
• Different discharge orientation
• Electronic and self-transformer speed regulators.
• Pre-filtered section
• Customised cabinet size
• Construction with the Aluminium extruded profile.
• Versions with double skin panels (20 mm thick) only in AL extruded profile.
• Blowers with EC motors are available on request. Performance of these blowers are not
certified by AMCA.
