Rheem-Ruud 70-102011-21 2-Blade Fan 18" DIA 26° Blade Angle 1/2" Bore CCW

The Rheem-Ruud 70-102011-21 plays the role of circulation of air in HVAC systems, which is an essentialcomponent of the system. The two blades of a 26-degree angle on this 18” diameter fan are designed to rotate in the anti-clockwise direction while the 1/2” bore diameter guarantees a tight fit on the fan motor shaft. The fan design is also used to improve the airflow and the energy reco and efficiency of the system and its operation. As it has been mentioned earlier, the HVAC system should be on for either cooling or heating depending on the requirements of the building. The angle and the number of the fan blades are well calculated to ensure that the air flows in a balanced manner thus reducing noise and increasing comfort.
