Claims21
A portable collector device for collecting particles and microorganisms present in ambient air, the device comprising
- a cyclone enclosure for centrifuging air, the enclosure including a wall defining an interior space of the enclosure, a top portion and a bottom portion that is detachable from the top portion, said bottom portion having an inner surface for collecting one or more of microorganisms and particles,
- an opening formed in said wall of the top portion of the enclosure, the opening defining an external air inlet for admitting air into the interior space of the enclosure, wherein air admitted into the interior space is centrifuged against the inner surface,
- an air outlet for discharging air from the enclosure, and a coupling member for coupling the air outlet of the enclosure to an air inlet of an individual motorized respiratory protection appliance, wherein the coupling member comprises a first tubular branch connected to the air outlet, and at least a second tubular branch configured to be connected to an inlet filter of the individual motorized respiratory protection appliance.
A portable collector device for collecting particles and microorganisms present in ambient air, the device comprising
- a cyclone enclosure for centrifuging air, the enclosure including:
- a wall defining an interior space of the enclosure;
- an external air inlet for admitting air into said interior space of the enclosure, wherein air admitted into the interior space is centrifuged within the interior space,
- an air outlet for discharging air from the enclosure, the air outlet comprising an axial tube that extends into the top portion of the enclosure and defines an annular air inlet channel between an inner surface of the enclosure and an outer surface of the axial tube, wherein the external air inlet leads tangentially into the annular air inlet channel, and
- a coupling member for coupling the air outlet of the enclosure to an air inlet of an individual motorized respiratory protection appliance, wherein the coupling member comprises a first tubular branch connected to the air outlet, and at least a second tubular branch having a bell-shaped endpiece that is configured to be connected to an inlet filter of the individual motorized respiratory protection appliance.
