摘要： A method of controlling a powered air purifying respirator blower system to detect a low air pressure high airflow event is disclosed. The blower system comprises a fan powered by an electric motor, controlled by an electronic control unit for delivering a forced flow of filtered air to a user. The electronic control unit has a plurality of data points representing events defining an acceptable operating range in terms of different characteristics of the blower system stored therein. The method comprises sampling a characteristic that represents the operating condition of the blower to obtain a sampled data point; comparing the sampled data point and the stored data point representing a low air-pressure high airflow event, for the same characteristic; repeating the sampling during a fixed time period, and if the comparing step indicates the low air-pressure high airflow event has been reached for the majority of the time period; activating an alarm. Use of a respirator employing the method to deliver a forced flow of filtered air to a contained user environment is also disclosed.

摘要： A method of controlling a powered air purifying respirator blower system to deliver a substantially uniform volumetric airflow to a user (6) includes the steps of determining one of (a) ambient air density or (b) ambient air temperature and ambient air pressure, and adjusting an electrical characteristic of the electric motor (22) in response to said determination and said at least two calibration values. The powered air purifying respirator blower system may include a fan (21) powered by an electric motor (22), the motor being controlled by an electronic control unit (23) for delivering a forced flow of filtered air to a user (06). The electronic control unit (23) may include at least two calibration values for the electrical characteristics of the electric motor (22) stored therein. The system may include at least one sensor (26) adapted to be in communication with the electronic control unit and arranged to determine one of (a) ambient air density or (b) ambient air temperature and ambient air pressure.
