Blower C105H2

Product catalog summary

Product Overview:
The C105H2-24AR-04-L3 is a miniature centrifugal blower designed with a metal housing and impeller. It features a three-phase brushless motor without a Hall sensor and includes an integrated driver. The blower is primarily intended for the medical device industry, but requires life testing and validation for use in life support equipment.

Specifications:

Dimensions: 117.5 x 102 x 132 mm (4.63 x 4.02 x 5.2 in)
Nominal Voltage: 24 VDC
Voltage Range: 10 - 28 VDC
Zero Flow Pressure: 18,500 Pa
Working Point Pressure: 13,400 Pa
Free Flow Rate: 846 lpm
Acoustic Emission Level: < 70 dB(A)
Resistance (Phase-Phase): 0.13 Ω ±25%
Inductance: 0.08 mH ±8%
Inertia: 932 g·mm² / 0.0510 oz·in²

Performance Notes:

Performance varies with driver and test conditions.
Data obtained at 20°C and sea level.
Performance may differ when used as a vacuum.

Electrical Connections:

Pin 1: N/A
Pin 2: Vcc
Pin 3: GND
Pin 4: Set speed input
Pin 5: Tachometer output
Pin 6: NTC

Power Supply Requirements:

Voltage: 8 - 30 V
Ripple Voltage: < 5%
Current: 10 A

Blower Limits and Warnings:

Max continuous speed: 52,000 rpm
No hot-swapping allowed.
Blocking the impeller for more than 20 seconds can cause damage unless current is limited.
Minimum airflow required at higher voltages to prevent overheating.
Over-current protection limits current below 10A.

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

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 then 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.
