The data in this spec. sheet was obtained using Boreasa test chamber at 20°C (±2°C) and sea level. It may be different than data measured in other conditions. - Specifications are subject to change without notice. - It is not possible to test fans in all conceivable customer application configurations. Consequently, to be used in specific equipment, fans must be tested and validated by customers, in their actual application conditions, in a statistically meaningful quantity.
