Description
The Xylem-Hoffman Specialty DP0708 Propeller Stem is an airflow control element that assists in supporting the movement of the blades and shutters in the HVAC systems. This connects with fan or damper systems, which offer a stable shaft to fix the blades and stable rotational feedback to drive inputs. It is intended to be used in air handlers, ventilation ducts or unit blowers, where the propeller blades are lined to ensure the correct pitch and balance are provided during use. It is fitted in areas where airflow needs to be regulated axially and assists in the controlled movement of air.
