The air filter cleaning device provides a tool for efficiently cleaning an air filter. the air filter cleaning device includes an elongated coil extending between a first end and a second end. The coil includes a surface that defines a hollow interior extending between first end and second end such that the coil is configured to be tubular. the elongated straight portion is connected with the actuator via the swivel joint. The coil is placed into the cavity of the air filter. The actuator is actuated, thereby causing air to enter the first end, flow through the interior and exit the opening. The pressure of the air exiting the opening causes the coil to rotate relative to the air filter. As the coil rotates, the pressure of the air pushes dust and/or debris from the porous material of the air filter.

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.

A pulse valve assembly including a main valve and a pilot valve that selectively actuates the main valve.

An air cleaning module includes a filter, a fan, a light source unit, a housing and a guide structure. The fan is configured to provide a suction direction and a blowing direction of a fluid which are substantially aligned. The light source unit is arranged to be adjacent to the filter to emit a light toward the filter. The light having a property that sterilizes a contaminant source in a fluid. The housing includes a fluid passage space. The guide structure is arranged between the fan and the filter and configured to guide a fluid to move along a fluid passage path set by the guide structure. The filter and the light source unit are arranged in the fluid passage space such that the light source unit sterilizes a fluid as a fluid flows toward the light source unit.
