    Abstract: The technology disclosed herein relates to, in part, a filter assembly. Filter media is arranged about a central media opening, where the filter media has a first end and a second end. The central media opening extends in an axial direction from the first end towards the second end. An endcap is coupled to the first end of the filter media. The endcap defines an opening in fluid communication with the central media opening, an inner surface abutting and surrounding the endcap opening, and a perimetric sealing surface about the endcap. A first portion of the perimetric sealing surface projects inwardly towards the endcap opening and a second portion of the perimetric sealing surface projects outwardly from the endcap opening. The first portion and the second portion are in axial alignment, and the perimetric sealing surface forms an oblong loop in a first cross-section orthogonal to the axial direction.

    Abstract: A filter system includes a tube sheet defining a plurality of holes in fluid communication with a plurality of filter bags. The system also includes a rotating assembly having an arm defining one or more outlets to provide pressurized air from an air source toward the tube sheet in response to pulsing one or more actuators. A motor is operably coupled to the stationary assembly and the rotating assembly to rotate the arm about an axis at a preset rotational speed. A controller is operably coupled to the motor and the one or more actuators to provide pulse commands based on a pulse interval and a jog interval. The pulse interval and the jog interval may be determined based on a measured rotational speed of the arm, which may be redetermined during operation.
