Ventilators provide temporary respiratory support to medical patients, often in critical care situations. Reliability and low audible noise are very important criteria to ventilator manufacturers. Medical ventilators must also be very versatile to cover patients from infants to large adults with differing treatment protocols.
A small, low-noise, power-efficient respiratory blower is required for such ventilators. Allied Motion's engineers developed the ResMax 28 brushless DC motor specifically for ventilators. It's high speed (90,000 RPM) and high dynamic performance enable high pressure (100 mBar) and peak flow (200 L/min) generation, while being highly dynamic to accurately follow patient breathing rhythms.
