DC fan is a high performer

Now available in the UK from Aerco is a new high performance DC fan from ADDA that is ideal for cooling modern, densely packed enclosures. The AD 12738 series is built in a 127mm x 127mm x 38mm frame size, has a rotor speed of 4,500 rev/min, produces airflow of up to 114 litres/sec (242 CFM) at a 150 Pa and is ideal for operating in confined spaces where high pressures occur.

Versions are available with supply voltages of 12V, 24V and 48V and the presence of tachometer and fan-failure signal wires mean that the AD 12738 can be incorporated into intelligent cooling systems.
High quality ball bearings provide a life of 70,000 hours at 40C.
