home carefor sleep apneaCPAP

Overview
The MFA0021 centrifugal blower (turbine) is designed for integration into Home Care ventilators, BiPAP and CPAP devices. It accepts oxygen injection upstream of the turbine and is intended for 100% oxygen compatibility. The unit is supplied without an external casing and is available with or without an inlet tube.

Design & variants
Derived from the MFA0020, the MFA0021 is configured without motor cooling management. Configurations include a bare turbine (no external casing) and an option to add an inlet tube to suit system packaging and flow requirements.

Highlights

• Oxygen-compatible: allows oxygen injection before the turbine for medical ventilation applications.
• Engineered for Home Care BiPAP and CPAP ventilators.
• Compact, economical centrifugal design suited to device integration.
• Available with or without inlet tube to match OEM integration needs.

Options

• Inlet tube: configurable with or without inlet tube according to installation and acoustic constraints.
