E-mail: [email protected], URL: www.boreasa.com Miniature Centrifugal Blowers * Housing and Impeller materials: Thermoplastics * Three Phase Brushless Motor w/ Hall Sensor * Note: This blower uses a brushless motor and needs a driver to operate NOTES: - Performances are dependent on the driver used and the test conditions. 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. - 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.
