An ammonia oxidation catalyst basket design has two support grids. A first grid supports the primary catalyst and a separate, second grid supports the secondary catalyst. This dual grid design separates the two catalysts, and enables the catalysts to be independent of each other. Any interruption in the primary or the secondary catalyst does not impede or adversely impact on the structure or function of the other catalyst.

A filter wrap for a cylindrical filter has a sheet with an interior side facing the filter when the sheet is wrapped on the filter, and an exterior side. It also has an edge defining a main opening to the interior for receiving the filter. At least one strap is provided for the wrap with one end attached to the sheet. The strap has another accessible distal end. Pulling on the strap(s) everts the sheet as it is pulled off of the filter. This results in trapping debris residing on the exterior of the sheet within the sheet once it is everted during removal of the wrap from the filter. Installation and removal can be performed while the protected equipment remains in operation.

A filter cartridge for use in severe or harsh applications, such as acidic or alkaline environments or hot or cold temperatures. The inventive filter cartridge is constructed of a central, perforated core having reinforcing bands on the ends which is surrounded by a continuous tube of filtration material and bounded by end caps. Rather than using potting compounds or other techniques which are susceptible to severe environments, the end caps are secured to the filter material enrobed core by way of mechanical fasteners, such as blind pop-rivets, screws, or nails.
