Abstract:
The cyclic flow apparatuses consistent with the technology disclosed herein are configured to sealably couple to a liquid flow circuit. The cyclic flow apparatus is configured to change a flow velocity of a liquid through a filter media holder. In various embodiments, the cyclic flow apparatus is configured to change the flow velocity of the liquid through a portion of the liquid flow circuit. The cyclic flow apparatus can be configured to cyclically change the flow velocity of the liquid in the liquid flow circuit through the filter media holder.
Abstract:
This disclosure describes a filter medium that minimizes the adverse effects of variations in flow rate on filter medium efficiency without a corresponding increase in pressure drop. The filter medium includes a support layer, a continuous fine fiber layer, and an efficiency layer. The continuous fine fiber layer includes a continuous fine fiber that has a diameter of up to 10 micrometers and is located downstream of the efficiency layer.
Abstract:
A pleated media pack includes a section of media configured into a tube defining an interior volume and an open opening at one end. A ratio of the pleat depth to a diameter of the opening is greater than 0.2. At least some of the pleats at one end of the media pack are inverted. In some examples, the pleats include major pleats alternating with minor pleats.
Abstract:
Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.
Abstract:
A fume extractor has an extractor housing (110, 210) defining an outlet (106, 206). A hose (120, 220) is coupled to the extractor housing that defines a first inlet (102, 202). A diffusion plate (130, 230) is coupled to the extractor housing that defines a plurality of openings (132, 232) cumulatively defining a second inlet (104, 204). A fan (280, 530) is disposed in the extractor housing, where the fan configured to connect each of the first inlet and the second inlet to the outlet. A first supporting surface (160) is opposite the diffusion plate relative to the extractor housing and a second supporting surface (170) at least 80° to the diffusion plate, where the first supporting surface and the second supporting surface are configured to selectively rest on a planar surface. The fume extractor defines a hose channel (140) configured to selectively receive the hose.

Abstract:
This disclosure describes filter media and mask filters and face mask systems including those filter media. In one aspect, the filter media includes a fibrous media including multi-component binder fibers, glass fibers, and microfibrillated cellulose fibers. In some aspects, the fibrous media further includes PET fibers. In another aspect, the filter media includes an electrostatically charged filter media, a fine fiber layer, and a scrim. In yet another aspect, the filter media includes two fine fiber layers, and two scrims. In additional aspects, the filter media includes bicomponent fibers, polyethylene terephthalate fibers, and microfibrillated cellulose fibers. In a further aspect, the filter media includes a support layer, a continuous fine fiber layer, and an efficiency layer. Combinations and composites of the filter media are also contemplated.
Abstract:
A pleated media pack includes a section of media configured into a tube defining an interior volume and an open opening at one end. At least some of the pleats at both ends of the media pack are inverted. In some examples, the pleats include major pleats alternating with minor pleats.
