A ball drain wye strainer valve assembly includes a wye strainer located adjacent to a T-ball valve within a unitary body. The ball drain wye strainer valve assembly includes an additional valve member. The combination of the valve members permits the flushing of the wye strainer screen from either upstream or downstream. A drain is also incorporated to allow for the system draining, flushing, or air-purging during the initial installation and subsequent maintenance of the screen and wye strainer.

A substrate processing device includes: a chamber; a substrate processing mechanism that has a holding member, and discharges a processing fluid onto a substrate held by the holding member; a joint pipe that has a lower opening provided below the holding member, and an upper opening provided above the holding member, and is disposed such that at least part of the joint pipe from the lower opening to the upper opening passes through the outside of the chamber; and an air flow generator that is provided in the joint pipe. The air flow generator circulates an atmosphere in the chamber by discharging the atmosphere in the chamber from the lower opening to the joint pipe to allow the atmosphere to pass through the joint pipe, thereby introducing the atmosphere again into the chamber via the upper opening so that a downflow of the atmosphere occurs in the chamber.

An electronic cigarette particularly adaptable to vaporize liquid material also having exhale filter function is disclosed herein. The exhale function is useful to prevent second hand smoke in an enclosed environment, for example. An innovative diverter valve assembly comprises a unique duckbill valve configuration diverting air through a cooker chamber and into a mouthpiece in an inhale function and diverting exhaled air around the cooker chamber in the exhale function and through a filter assembly. A preferred embodiment further introduces a unique shape to the smoking instrument being elliptical in the cross-section and tapering to proximal and distal ends.

An air filtration system is provided. The system includes one or more air delivery pipes disposed above, and in fluid communication with, an occupiable space. The delivery pipe supplies clean air to the space through a plurality of air apertures disposed along a length of the air delivery pipe. The apertures are configured to provide a flow of air out of the air delivery pipe that is constant along the length of the air delivery pipe. A similar one or more air exhaust pipes are disposed below, and in fluid communication with, the occupiable space.

A flue pipe filter device for reducing nitrogen oxide (NOx) emission levels from gas fired appliances may include a flue cap with a pipe connection adapter sized to attach to an existing exhaust pipe; a fanned flue cap body with vents operatively attached to a distal end of the pipe connection adapter; and a filter positioned within the fanned flue cap body, the filter designed to convert NOx emissions into reduced NOx emissions. The filter may have an interior honeycomb structure.

An air filtration system includes a main body having a flow path; a first filter portion provided on the flow path and having a first body portion; a plurality of protrusions distributed and disposed on the first body portion; and a plurality of first through holes passing through the first body portion and interposed between the adjacent protrusions; wherein when an external fluid flows in the flow path, the external fluid passes through the protrusions first and then passes through each of the first through holes, so that the flowing external fluid is hindered by the protrusions, and thus a flow velocity at a position adjacent to the protrusions is lower than a flow velocity flowing through the first through holes, thereby vortices are respectively generated between orifices of the first through holes and the adjacent protrusions. The present invention discloses an air filtration system including: a main body having a flow path; a first filter portion provided on the flow path and having a first body portion; a plurality of protrusions distributed and disposed on the first body portion; and a plurality of first through holes passing through the first body portion and interposed between the adjacent protrusions; wherein when an external fluid flows in the flow path, the external fluid passes through the protrusions first and then passes through each of the first through holes, so that the flowing external fluid is hindered by the protrusions, and thus a flow velocity at a position adjacent to the protrusions is lower than a flow velocity flowing through the first through holes, thereby vortices are respectively generated between orifices of the first through holes and the adjacent protrusions, so that particulates contained in the external fluid stay in static areas outside the vortices.

Filters (including curved filters) and filter arrangements comprising a plurality of filter arms, each arm comprising a hollow tube, each hollow tube having a first end and a second end, and a tube inner fluid channel having an inner diameter; the filter further including a first tube connector, comprising a first hollow body having a first hollow body inner diameter, connected to, and in fluid communication with, the hollow tubes, wherein the first hollow body inner diameter is greater than the tube inner fluid channel inner diameters, and filter devices including filters and filter arrangements, and methods of use are disclosed.
