摘要： An air filtration system (10) and a helmet (12) for use in the air filtration system are disclosed and utilized to filter air between a user's head and body and the external environment. The air filtration system and helmet include inner (18) and outer (20) shells that define an air flow channel (26) for channeling air to a user. A fan module (46) is mounted between the inner and outer shells and a scrool housing (48) which is mounted adjacent the fan module. The scroll housing (48) includes an air inlet (64) and at least one air outlet (66) for distributing air flow into the air flow channel (26). The helmet (12) includes front (76) and rear (78) air exits in fluid communication with the air flow channel (26) and the at least one air outlet (66). The air filtration system (10) includes a gown (88) operating as a filter for filtering the air.
