The data in this spec. sheet was obtained using Boreasa test chamber at 20°C (±2°C) and sea level, and using a Boreasa D30/5/4Q-E2 driver. It may be different than data measured in other conditions or with other drivers. - When used as a vacuum, the blower performance might be less than shown herein, depending on the operating point. - Specifications are subject to change without notice. - Boreasa blowers have been designed and are manufactured to meet the medical device industry requirements. However, it is not possible to test blowers in all conceivable customer application configurations. Consequently, to be used in life support equipment, blowers must be life tested and validated by customers, in their actual application conditions, in a statistically meaningful quantity.
