Blower C65MS1

Product catalog summary

Specifications:
The C65MS1-24PR-04-Lx is a miniature centrifugal blower designed with medical-grade thermoplastics. It features a three-phase brushless motor without a Hall sensor and an integrated driver. The blower operates within a temperature range of -20 to +50°C (-4 to +122°F) and weighs 235 grams (8.29 oz). It is available in a 12 V version upon request.

Technical Data:
The blower operates at a nominal voltage of 24 VDC, with a voltage range of 10 to 28 VDC. Performance metrics include zero flow pressure of 4,570 Pa and 7,200 Pa for different models, with corresponding current and speed values. The working point pressure is 3,390 Pa and 5,050 Pa, with flow rates of 220 lpm and 255 lpm, respectively. The blower's acoustic emission level is below 52.5 dB(A), and it has a lifespan of over 20,000 hours at 25°C.

Electrical Connections:
The blower uses AWG22 wires for power supply, ground, speed control voltage (VSP), and frequency generator (FG). The speed is calculated as 20 times the FG value. Speed control is achieved through a voltage range of 0 to 3.3 V, with specific voltage thresholds for stopping and full speed.

Power Supply Requirements:
The blower requires a voltage of 10 to 28 VDC with a ripple voltage of less than 5% and a current of 3.5 A. It includes over-current protection, limiting the current below 3.5 A.

Blower Limits and Warnings:
The blower should not be hot-swapped, and the maximum temperature on the heat sink should not exceed 75°C. Continuous speed should not exceed 52,000 rpm, and blocking the impeller for more than 20 seconds may cause damage. A minimum airflow is necessary at voltages higher than nominal to prevent overheating.

Manufacturing Standards:
The blowers are manufactured by an ISO9001-2015 certified manufacturer.

Typical Hookup:
The document provides guidance on measuring generator frequency to calculate blower speed, using external power supplies and potentiometers for speed control, and ensuring proper connections for optimal performance.

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. - 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.
