Abstract
A headgear-mountable respirator (100) including a first intake (106A) and first associated impeller (108A), as well as a second intake (106B) and second associated impeller (108B) located remotely from the first intake and the first impeller. The respirator further includes a device (112) for, in use, rotating at least one of the impellers, and an air delivery arrangement (103A, 103B) for, in use, delivering air drawn from the first and second intakes to a facial region of a user.

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, and
- an 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.
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, and
- an 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.
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, and
- an 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′);
- and
- the nub (412) is generally triangular in shape, and at least some components of the respirator include an explosion proof housing (104).
