CA 2706376

A modular powered air purifying respirator (PAPR) which is comprised of a fan, motor, scroll, and power source mounted within one housing, and which accepts either traditional or conformal filters. Ambient air is drawn into the PAPR module through the attached filter by a fan, which is driven by direct connection to a motor. The pressurized air is then accelerated by an optimized scroll to the outlet in the PAPR housing. The PAPR module can be employed in multiple use configurations.

L'invention concerne un respirateur purificateur d'air alimenté (PAPR) modulaire qui est composé d'un ventilateur, d'un moteur, d'une hélice et d'une source d'alimentation montée à l'intérieur d'un boîtier, et qui accepte soit des filtres traditionnels, soit des filtres conformes. De l'air ambiant est aspiré dans le module PARPR par l'intermédiaire du filtre joint par un ventilateur, qui est entraîné par une connexion directe à un moteur. L'air sous pression est ensuite accéléré par une hélice optimisée vers la sortie dans le logement PAPR. Le module PAPR peut être employé dans de multiples configurations d'utilisation.
