New high performance large frame AC fans

The ADDA AK178 and AK186 provide the same airflow performance but are built in different frame sizes to suit different applications. The AK178 measures 176 x 176 x 89mm while the AK186 is 180 x 180 x 65mm. Both are powered by a new high performance capacitor motor that is more efficient, producing a higher output while consuming less power than shaded pole motors that are often used for this type of fan.

Both fans produce airflow of 805 litres/sec (380 CFM) at a nominal speed of 2,650 rev/min and have an anticipated lifetime of 50,000 hours at 40ºC.
