The invention relates to a filter element (10), including a filter body (12) with a self-contained exterior side (50) which surrounds a self-contained interior side (52), at least one filter medium (16) being disposed between exterior side (50) and interior side (52) and the filter body (12) including at least in some areas at least one winding layer (14) with at least one adsorbent. The invention relates furthermore to a filter system (100) with a filter element (10) with a filter body (12) with a self-contained exterior side (50) which surrounds a self-contained interior side (52), at least one filter medium (16) being disposed between exterior side (50) and interior side (52), the filter body (12) including at least in some areas at least one winding layer (14) with at least one adsorbent.

Disclosed is an activated carbon including pores formed on a surface thereof, in particular, the pores include ultra-micropores having a diameter that is equal to or less than about 1.0 nm.

An air-conditioning system comprises a channel system, a system conveying device positioned in the channel system and configured to convey air in the channel system, a sensor device comprising at least one analysis channel and configured to measure a characteristic of air flowing through the at least one analysis channel, and a suction jet pump comprising a motive-fluid inlet, a suction inlet, and a pump outlet. The system conveying device separates a suction area of the channel system arranged upstream of the system conveying device from a pressure area of the channel system arranged downstream from the system conveying device, and the sensor device further comprises a sensor outlet configured to release air from the sensor device. The motive-fluid inlet is fluidically connected to the pressure area via a suction jet branch-off point within the channel system, and the suction inlet is fluidically connected to the sensor outlet.

The present invention relates to systems and methods for conrolling the atmosphere in the cabin (1) of a vehicle. The system comprises a carbon dioxide removal conduit (2) comprising a regenerable carbon dioxide removal chamber (5,6) containing a carbon dioxide sorbent material and a regeneration circuit (7) arranged to expel the desorbed carbon diocide at a location exterior (8) of the cabin (1) The system is operable to maintain a carbon dioxide level below 1000 ppm in the passenger cabin for a period of at least 5 minutes while restricting the flow of air from outside the vehicle into the passenger cabin to 10 L/s or less.

A collective NBC filtration system (FIG. 1A) for providing positive-pressure purified air to a plurality of subjects in a protected space, or in an environment which cannot be maintained at positive pressure, in conjunction with one or more facepiece fluidly connected to the NBC filtration system. The system comprises: A casing body [102] including a first section [136] defining an inner volume therein, and a second section [138] adjacent to the first section. The second section includes an inlet port [116], The first section has a larger cross-section than the second section, and forms a peripheral first ledge [142] surrounding the second section. At least one NBC filter accommodated in the inner volume. The at least one NBC filter is supported on the first ledge [142], A lid [104] including a central portion [154] and a second ledge [152] surrounding the central portion. The central portion [154] includes a plurality of outlet ports [118], which are sealable. The lid [104] is openable to provide access to the inner volume and is securely closeable to affix the at least one NBC filter therein the inner volume by the second ledge [152], The lid [104] and the at least one NBC filter define, when the lid is securely closed, an outlet compartment there between. The outlet compartment has about the same cross-section as the second section. A blower [108] housed within the second section. A suction port of the blower being fluidly coupled to the inlet port. The system is configured such that the second section [138] fluidly couples the inlet port [116] to at least one inlet of the respective at least one NBC filter, and, when the lid [104] is securely closed, the outlet compartment [302] fluidly couples at least one outlet of the respective at least one NBC filter to the one or more outlet ports [118] but is otherwise fluidly sealed, thereby preventing potentially contaminated air from entering the outlet compartment, except via the at least one NBC filter.

A vehicle comprising, a passenger cabin, a door to the passenger cabin, and an air conditioning system is disclosed. The air conditioning system comprise a Peltier device, a blower for directing an airflow over a first side of the Peltier device and ducting for ducting air to the blower, the ducting comprising an inlet located on an underside of the door.

A vehicle comprising a passenger cabin and an air conditioning system is disclosed. The air conditioning system comprises a Peltier device, a first blower for directing a first airflow over a first side of the Peltier device, and a second blower for directing a second airflow over a second side of the Peltier device. The second blower draws the second airflow from inside the passenger cabin, and the second airflow is discharged to outside the passenger cabin.

A method for purifying air within a space is provided. The method includes a controller determining whether an ON signal is received. Upon determining that the ON signal is received, the controller instructs an air sanitizer of an air sanitization system to turn ON to purify an airflow passing through the air sanitization system, and instructs an air movement fan/blower to operate in order to direct the airflow into the space. Upon determining that the ON signal is not received, the controller instructs the air movement fan/blower and the air sanitizer to be OFF.
