Product details
The CAN Iso-Max fans are the Air Force II Acoustic Fans with new branding, as ever the fans incorporate high-quality,high-air movement Etaline fan motors into sealed acoustic cases. They can move very large amounts of air quietly and are much better at pulling air through carbon filters than standard fans. As well as being surprisingly lightweight for fans of this size and quality,the Iso-Max fans also use low-energy motors so they don’t require as much electricity but still maintain high levels of torque to handle carbon filters.
