  • U. S. Patent No. 5,035,240 issued 30 Jul. 1991 to Braun et al. describes a type of non-woven filtration material for the removal of paniculate matter from ambient air that is useful as a prefilter on respirators, and such a respirator is also described.
  • the material is formed specifically as thermoplastic elastomeric melt-blown small diameter fibers.
  • the filtration properties of the product can be adjusted by fiber size selection, and also by incorporation therein of crimped spacing staple fibers, electrically charged or chargeable fibers, or fibrous clusters into the web matrix, or also sorbent particulate material.
  • HVAC heating, ventilation and air conditioning
  • the longitudinal structure of air baffle 40 and fan frame 92 is provided by a series of fan/baffle braces 122, which extend perpendicularly (downward in Fig. 8) from second fan strut 120 with mutually parallel relationships therebetween. Distal ends of fan/baffle braces 122 then connect to first baffle strut 124, and then at a predetermined distance from second fan strut 120 to a second baffle strut 126 that lies in a mutually parallel relationship with first baffle strut 124. Second baffle strut 126 constitutes the longitudinally peripheral member of fan frame 92 in the direction from which the air to be purified is drawn.
  • FIG 1 also shows an air flow switch 88 on the rightward side of the outlet end of PAP 10.
  • Air flow switch 88 can be an ordinary type of speed control switch, or in the case of the embodiment of PAP 10 shown in Fig. 1 that has three fans 42, air flow switch 88 can consist of three independent "on-off" switches that would serve instead to connect just one, or two, or all three of fans 42 to batteries 72 both to provide an "OFF" condition and to permit selection between those three levels of air speed of the air passing through PAP 10.

Abstract

L'invention concerne un purificateur d'air portable personnel autonome (10) comprenant une séquence présélectionnée de paquets de couches filtrantes à lit à garnissage (28) renfermant des couches filtrantes de types spécifiquement destinés à absorber une gamme de polluants atmosphériques identifiés comme particulièrement dangereux pour la santé humaine. L'invention concerne également un filtre HEPA (30) destiné à capturer une matière particulaire se fixant à plusieurs de ces polluants, et notamment aux oxydes de soufre et d'azote provenant de la combustion du diesel. Les types de couches peuvent être sélectionnés de façon à correspondre à différentes conditions environnementales, telles que l'air normal environnant une autoroute ou un centre urbain, une attaque terroriste de type chimique, biologique ou nucléaire ('bombe sale'), un champ de bataille ou des environnements similaires. Un conduit d'air (48) situé au voisinage de la sortie d'air (36) est conçu pour recevoir un tuyau auquel peut être raccordé un masque ou un autre dispositif de respiration, habituellement avec un sac à air associé du type utilisé dans les masques à oxygène pour avions. De l'énergie électrique (72, 76, 172) destinée à l'actionnement de ventilateurs (42) permettant d'aspirer l'air ambiant à travers le dispositif est fournie par un réseau de batteries remplaçables et/ou rechargeables (72, 172) connectées à un appareil de vérification des batteries (90). Une entrée d'alimentation (76) destinée à une fiche d'alimentation est également utilisée, le purificateur d'air (10) pouvant être connecté à une sortie d'allume-cigare dans un véhicule à moteur. Des bretelles (54) et une sangle de poitrine (56) permettent à un utilisateur de porter ce dispositif sur son dos, une pochette portée sur l'épaule (176) pouvant également être utilisée. Les quantités de couches filtrantes utilisées ainsi que les exigences de puissance et les moyens de fourniture de l'énergie sont déterminés en vue de maximiser la quantité de polluants éliminés de l'air traversant ce dispositif et la durée du fonctionnement autonome.
