Tower fan electric fan performance testing system IEC60879

1Testing requirements for tower fans and bladeless fans

The distance from the geometric center of the fan blade or air outlet to the ground must be at least:The scanning size is 1200 Millimeters, or equivalent scanning size(Bladeless fan)not greater than 400 millimeter;

Or the scanning size is 1500 Millimeters, or equivalent scanning size(Bladeless fan)greater than 400 millimeter

The distance between the air outlet plane of tower fans and bladeless fans and the rear wall, or the distance between the blade plane of fans other than tower fans and bladeless fans and the rear wall, must be at least 1200 millimeter

The distance from the air outlet plane of tower fans and bladeless fans, or the blade plane of fans other than tower fans and bladeless fans, to the front wall must be at least:

The scanning size is 1800 Millimeter or equivalent scanning size(Paddleless fan)not greater than 400 millimeter;

Or the scanning size is 4000 Millimeter or equivalent scanning size(Bladeless fan)greater than 400 Millimeters.

The plane of the blade anemometer is parallel to the air outlet plane of the tower fan and bladeless fan, and parallel to the blade plane of fans other than the tower fan and bladeless fan. The distance between two planes is based on the scanning size 3 Multiple or equivalent scanning size(For bladeless fans)The tolerance is± 15millimeter
