Embodiments of an emission recovery system of the present invention generally include an inverted, substantially U-shaped tubular head, and a substantially straight, vertically oriented tubular body internally equipped with one or more fans and a plurality of liquid spray nozzles fluidly connected to a liquid provision system. Embodiments of a method of using an embodiment of an emission recovery system of the present invention are also provided.

An air cleaner assembly and components therefor are provided. Features are described providing for installation of a preferred filter cartridge in a housing. A filter cartridge arrangement is described and shown. Methods of assembly and use are also described.

A smoke evacuation device includes one or more cooling mechanisms and an exhaust mechanism to reduce velocity and noise of filtered air exiting the smoke evacuation system. The cooling mechanism includes ventilation openings and/or a rotary mechanism disposed within the system to circulate air and cool by convective heat transfer. A pressure relief mechanism is also provided at the inlet or outlet of the system or the pump within the system. The pressure relief mechanism is configured to reduce pressures due to abnormal flows within the smoke evacuation system.

A filtration device, in particular a disposable filtration device, has a flow path in which a filter element and an integrated flow reducer are arranged one behind the other. The flow reducer is adapted to be brought to a first operating position, which permits a defined first volume flow rate, and at least to a second operating position, which permits a defined second volume flow rate which is smaller than the first volume flow rate.

An air cleaner assembly and components therefor are described. The components include features of an air cleaner housing; advantageous main filter cartridges; and, advantageous safety filter cartridge features. Features of the main filter cartridge are provided to engage an access cover of the assembly, and a cartridge support within the housing, in a preferred manner. Methods of assembly and use are also described.

The filter vessel attachment/detachment apparatus includes a first conduit end, wherein a first conduit for the fluid to flow through is coupled to the first conduit end, and the first conduit end has a clamping portion capable of clamping the flange of the filter vessel; a contact surface capable of strongly contacting to the inlet or the outlet of the filter vessel; and a guide member capable of, for a direction from the first conduit toward the inlet or the outlet, rotating about a second axis separated from a first axis by a predetermined distance, the first axis being from the first conduit toward the inlet, the guide member having a holding portion capable of holding the inlet or the outlet.

An in-line vacuum filter comprises a manifold having an inlet, an outlet, a collecting container, and an actuatable filter paddle. A flow of air generated by a source of negative pressure travels from the inlet to the outlet. The actuatable filter paddle is positioned within the manifold such that it can be actuated between a first position and a second position. In the first position, the actuatable filter paddle is placed within the flow of air and in the second position, the actuatable filter paddle is removed from the flow of air. The filter paddle is preferably arcuate concave and comprises a plurality of apertures. In the first position, the filter paddle gradually diverts objects larger than a width of the apertures away from the flow of air. Diverted objects may travel to a removable collection container.

A refrigerator including a cabinet, a liner defining a compartment within the cabinet, a fan to move cooled air, and an air tower positioned adjacent the liner and provided in fluid communication with the compartment via a plurality of primary exhaust openings. The refrigerator further includes an air filter bracket separate from and located adjacent to the air tower and provided in fluid communication with both the air tower and the compartment. The air filter bracket includes a duct positioned adjacent the flow path of the air tower to be in fluid communication with a secondary exhaust opening of the air tower.

A filter connection for a smoke evacuation device includes a filter canister assembly and a socket. The filter canister assembly has a cross-sectional shape with only one line of symmetry that corresponds to a cross-sectional shape of the socket so that the filter canister can only be inserted into the socket in one orientation. One or more key notches on the filter canister may also ensure that the filter is properly installed. A seal creates an airtight boundary between the filter canister and a recess of the socket so that a sealed path in communication with the smoke evacuation device is established before the filter canister is fully inserted into the socket. An electronic connection is made between the filter canister and the socket after the airtight boundary is created.

When drawing down drinking water stored in an enclosed reservoir, air must be utilized to displace the drawn-down drinking water in order to ensure an acceptable level of drinking water outflow. If the intake air is not clean, or if debris is carried by the intake air into the reservoir tank, contamination of the drinking water may commence. Such contamination or build-up of unwanted particulates is obviously not desirable. The reservoir inlet air cleaning system serves to prevent potentially contaminating materials carried by the atmosphere from entering the reservoir tank. The system is scalable to reservoirs of all sizes, and thus may be customized for a particular use or for a particular location. An exemplary embodiment of the reservoir inlet air cleaning system may include a filtration unit, an air conduit, a means for controlling air intake so that other potential points of air inlet are closed off, means for controlling both condensate accumulation and contamination in the air conduit (and the reservoir tank), and means for preventing partial vacuum conditions and over-pressure conditions within the reservoir tank (or the air conduit) so as to avoid damage that may be caused by partial vacuum conditions and over-pressure conditions.
