New ADDA DC fan for high cooling applications

Edited by the Processingtalk editorial team Feb 20, 2008

A new high performance ADDA DC fan meets the high cooling requirements of modern computer server equipment and other high density equipment cabinets

The new AD1324HB fan from Aerco has been manufactured in the larger frame size of 127 x 127 x 38mm and produces 110.3 litres/sec (242 CFM) in free air at nominal voltage and a maximum static pressure of 15.75mmH2O at zero air volume.

This new fan is also available in a low noise version that, while operating at 2000 rpm, produces 48.8 litres/sec (107 CFM) at a noise level of 41dB/A.

This is 2dB/A lower than a 120 x 120 x 38mm size fan with a similar air delivery.

Operating from a 24VDC supply the fan is protected against locked rotor condition, with automatic restart, has an operating temperature range of -10C to +70C at 65% (+/-20%) relative humidity and is available with several different function signals including any combination of alarm detection, speed detection (tacho) and PWM.

Precision ball bearings provide a life expectancy of 50,000 hours at 40C and 65% RH.
