Aerco have introduced the ADDA 1224HB, a high-performance dc axial fan. It is one of a new generation of ADDA dc dans, showing a marked improvement in performance over its predecessor.
Built in a 120 x 120 x 38mm frame size, this 24V fan operates from a supply voltage of between 17 and 26.4VDC. It produces airflow of 94.4 litres/sec (200 CFM) in free air at nominal voltage, and a maximum static pressure of 16mm H2O at zero air flow.
This increase in airflow is due to enhanced venturi technology and a new, high-performance dc motor that runs at 4,300 rev/min with an operating noise level of only 61dBA.
Life is 50,000 hours at 40ºC, made possible because of a precision ball bearing system. The fan is also RoHS compliant.
