HEE-315I 12 Inch 976 CFM Metal Circular Centrifugal Duct Fan

Design: Strengthen the painting body: reinforce the body to resist compression and shock, the whole body is spray-painted, with strong corrosion resistance and dirt resistance This fan can withstand high pressure and is able to operate in long pipes at low noise levels. The fan motor is a built-in automatic reset thermal protector and NSK ball bearing. Easy to maintain: Lighter material fans can be easily cleaned when you deem it necessary. Moreover, certain fans have self-cleaning characteristics, making daily maintenance that much easier. The aerodynamically designed centrifugal impeller of this unit delivers strong airflow with a disproportionately low sound profile. Eco: According to aerodynamics, the balanced blades are engineered to minimize noise and vibration, they are ideal for boosting supply air, return air, or venting. The fan is balanced on both sides, with low vibration, balance precision level is G2.5. Remove heat from the system to solves air delivery problems witho
