Title (EN) METHOD OF CONTROLLING A POWERED AIR PURIFYING RESPIRATOR
(FR) PROCÉDÉ DE COMMANDE D'UN RESPIRATEUR PURIFICATEUR D'AIR ÉLECTRIQUE
Abstract:
(EN) There is provided a method of controlling a powered air purifying respirator blower system to deliver a substantially uniform volumetric airflow to a user, the system comprising a fan powered by a variable speed electric motor, the motor is controlled by an electronic control unit for delivering a forced flow of air through at least one filter to a user, comprising the steps of: (a) monitoring system loading; and (b) decreasing a speed of the electric motor when system loading reaches a predetermined value. There is also provided an air purifying respirator blower system using such a method.
(FR) L'invention concerne un procédé de commande d'un système de ventilateur de respirateur purificateur d'air électrique pour fournir un écoulement d'air volumétrique sensiblement uniforme à un utilisateur, le système comprenant un ventilateur alimenté par un moteur électrique à vitesse variable, le moteur est commandé par une unité de commande électronique pour distribuer un écoulement d'air forcé à travers au moins un filtre à un utilisateur, comprenant les étapes consistant à : (a) surveiller la charge du système; et (b) diminuer la vitesse du moteur électrique lorsque la charge du système atteint une valeur prédéterminée. L'invention concerne également un système de ventilateur de respirateur purificateur d'air utilisant un tel procédé.
