Abbaka’s Hy-Ex roof or exterior wall-mount ventilator offers a roof exhaust that is less obtrusive than those of standard ventilators. The kitchen range hood ventilator produces only 66dB at roof level and features permanently sealed ball bearings, thermal overload protection, a dual-pane dynamically balance blower wheel (for lower vibration), and external rotor construction that continually cools the motor. The unit has an optional powdercoated enamel finish. abbaka.com
