Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. The filter bag assemblies include a flange assembly, a cage attached to the flange assembly, and a filter bag installed over the cage with an opening at the flange assembly. When installed in the dirty air chamber of the air filter system, a seal between the flange assembly and the tubesheet defining the dirty air chamber is provided by applying a seal force on the end of the filter bag assembly located proximate the access panel on the side of the dirty air chamber opposite the tubesheet. That seal force is transmitted to the flange assembly through the cage. The tubular filter bags may be in the form of triangular bags and/or may include bag support connectors at the closed end of the bag.

Air filter systems, filter bag assemblies, filter bags and methods

Filter bags, filter bag support assemblies, and filter bag assemblies are described herein. The filter bags, filter bag support assemblies, and filter bag assemblies may be used in air filter systems to remove particulate matter from air or other gases. Methods of using the air filter systems and methods of assembling the filter bag assemblies are also described.

Enlarged opening filter bags, support assemblies, and filter bag assemblies

Embodiments herein relate to filter restriction indicator () for a filtration system. In an embodiment, a filter restriction indicator () can have an electronics control cartridge () including an internal spacer frame (), a first circuit board (), a second circuit board () disposed over the first circuit board (), and a pressure sensor () in electrical communication with the first circuit board (). A filter fluid tube () defines a filter fluid channel () in fluid communication with the pressure sensor (). The internal spacer frame () can secure the first circuit board () at a fixed distance from the second circuit board (). A lower housing () defines an ambient pressure port (). A cap () defines an interior volume () into which the electronics control cartridge fits (). The cap () can define a shielding panel () configured to fit over an exterior portion of the ambient pressure port () when the cap () is engaged with the lower housing (). Other embodiments are also included herein.
