An incubator for cell and tissue culture under controlled atmospheric conditions has a primary air flow control device that forms a primary, preferably laminar flow, air veil across an opening that allows access to the cells or tissue cultures disposed within the incubator. Preferably, most if not all of the air in the primary (laminar flow) air veil is recirculated, and a secondary air flow control device is used that forms a secondary, preferably laminar flow, air veil between the primary (laminar flow) air veil and a user of the incubator.

A dust extraction device for filtering air, the dust extraction device including one or more filter housing, each having at least one air filter, an inlet housing fluidly connected to the filter housing, a fan assembly including a fan, a fan inlet and a fan outlet, the fan assembly fluidly connecting the filter housing to the fan outlet, and a support frame for supporting the filter housing, inlet housing and the fan assembly.

Mist and vapor eliminating filters, devices, methods of filtering aircraft air using the devices, and systems including the devices, are disclosed.

Embodiments provide a filter with a generally rectangular, non-cylindrical profile. The filter may have multiple pleat packs positioned between pleat covers that define regions and flow channels in a cavity of the filter body. The pleat covers have openings that allow a fluid to flow through the multiple pleat packs via parallel flows or series flows. End caps bonded to the body define flow passages for directing the fluid from an inlet to an outlet via the pleat packs for series or parallel filtration. The pleat packs may be made of the same or different materials and may be configured with the same or different heights based on flow requirements. A cage or a separator may be positioned between the pleat packs. The pleat packs may be made of a continuous pleated membrane with bridges defining a space between the pleat packs to accommodate the cage or separator.
