1. A headgear-mountable respirator (100) including: a first intake (106A) and first associated impeller (108A);a second intake (106B) and second associated impeller (108B) located remotely from the first intake and the first impeller;a device (112) for, in use, rotating at least one of the impellers
1. A headgear-mountable respirator (100) including: a first intake (106A) and first associated impeller (108A);a second intake (106B) and second associated impeller (108B) located remotely from the first intake and the first impeller;a device (112) for, in use, rotating at least one of the impellers, andan air delivery arrangement (103A, 103B) for, in use, delivering air drawn from the first and second intakes to a facial region of a user, the air delivery arrangement including a first conduit (103A) leading from the first impeller (108A) toward the facial region and a second conduit (103B) leading from the second impeller (108B) toward the facial region, wherein the first (103A) and/or the second (103B) conduit is/are transverse to an axis of the first (108A) and/or the second (108B) impeller. 2. A respirator according to claim 1, wherein the second intake (106B) is opposed to the first intake (106A). 3. A respirator according to claim 2, wherein the first impeller (108A) and the second impeller have a common axis. 4. A respirator according to claim 1, wherein the rotating device (112) rotates both the first (108A) and the second (108B) impellers. 5. A respirator according to claim 4, wherein the rotating device (112) is located between the first (108A) impeller and the second (108B) impeller. 6. A respirator according to claim 5, including a central conduit (110) between the first (108A) and the second (108B) impeller, the rotating device (112) being located in the central conduit. 7. A respirator according to claim 1, wherein first and second conduits (103A, 103B) are substantially perpendicular to the axes. 8. A headgear-mountable respirator (100) including: a first intake (106A) and first associated impeller (108A);a second intake (106B) and second associated impeller (108B) located remotely from the first intake and the first impeller;a device (112) for, in use, rotating at least one of the impellers, andan air delivery arrangement (103A, 103B) for, in use, delivering air drawn from the first and second intakes to a facial region of a user, wherein the air delivery arrangement (103) directs at least some of the air drawn from the intakes (106) towards a visor portion of the headgear item, thereby providing a de-misting function. 9. A respirator according to claim 1, further including a removable filter (118) fitted to the first (106A) and/or the second (106B) intake. 10. A respirator according to claim 1, wherein the respirator (100) is directly or indirectly mounted on a peak portion (420) of a headgear item. 11. A respirator according to claim 10, wherein the respirator (100) is mounted on (or integrated with) a releasable portion (404) that is releasably attached to the peak portion (420). 12. A respirator according to claim 11, wherein the releasable portion (404) has a shape or profile that generally corresponds to a shape or profile (424) in the peak portion (420). 13. A respirator according to claim 12, wherein the releasable portion (404) includes at least one formation (412) that, in use, allows the releasable portion to slidably fit into the shape/profile of the peak portion so that the releasable portion is in a fitted configuration, but hinders/prevents removal of the releasable portion from the fitted configuration. 14. A respirator according to claim 13, wherein the at least one formation comprises a nub (412) with an angled edge (414′). 15. A headgear-mountable respirator (100) including: a first intake (106A) and first associated impeller (108A);a second intake (106B) and second associated impeller (108B) located remotely from the first intake and the first impeller;a device (112) for, in use, rotating at least one of the impellers, andan air delivery arrangement (103A, 103B) for, in use, delivering air drawn from the first and second intakes to a facial region of a user, wherein: the respirator (100) is directly or indirectly mounted on a peak portion (420) of a headgear item;the respirator (100) is mounted on (or integrated with) a releasable portion (404) that is releasably attached to the peak portion (420);the releasable portion (404) has a shape or profile that generally corresponds to a shape or profile (424) in the peak portion (420);the releasable portion (404) includes at least one formation (412) that, in use, allows the releasable portion to slidably fit into the shape/profile of the peak portion so that the releasable portion is in a fitted configuration, but hinders/prevents removal of the releasable portion from the fitted configuration;the at least one formation comprises a nub (412) with an angled edge (414′); andthe nub (412) is generally triangular in shape, and at least some components of the respirator include an explosion proof housing (104). 16. A headgear item including a respirator according to claim 1, including a mounting member (404) adapted to mount the respirator on a peak portion of the headgear item, the mounting member including an arrangement (412) releasably attaching the mounting member to the peak portion.
