An apparatus and method for an air filter media and frame having structural support members, including a tensile support member.

Air filter with tensile support member

A deep bed scrubber filter section comprises includes an unfiltered air input end, a filtered air output end, an airflow filtration path extending from the unfiltered air input end to the filtered air output end, a plurality of media beds along the airflow filtration path in series arrangement with one another, the media beds each having a media bed volume and each being defined by a plurality of sidewalls, two of the sidewalls of each of the media beds being perforated sidewalls at least partially intersecting the airflow filtration path, wherein an adjustable sidewall of at least one of the perforated sidewalls of a first media bed of the media beds is independently removable from the airflow filtration path and is independently adjustable to a plurality of positions along the airflow filtration path, wherein adjustment of the at least one adjustable sidewall of the first media bed alters the media bed volume of the first media bed.

Air handling filtration equipment with adjustable media bed and method of use

A method of transferring filter media between a media bed of a dry scrubber and a filter media container, comprising placing the media bed in flow communication with the filter media container, obstructing a majority of an airflow path of the media bed, the airflow path extending from an unfiltered air input opening of the dry scrubber, through the media bed of the dry bed scrubber, to a filtered air output opening of said dry bed scrubber, powering a blower in the airflow path of the media bed when the airflow path is obstructed and the media bed is in flow communication with the filter media container, whereby the filter media is transferred between the media bed and the filter media container.

A air gas detection pack is provided. The air gas detection pack has a card receiving pocket which slidably receives a gas detection card, the gas detection card having a plurality of chemically reactive materials retained therein and exposed to outside air through a plurality of aligned air permeable apertures formed in the front and rear wall of the substance detection pack. The combined gas detection card and gas detection pack indicates the concentrations of gases in the air. The air permeable apertures in conjunction with the reactive materials of the substance detection card are covered with a filtering media to protect the reactive material from dirt and dust contamination.
