A filter assembly comprises a filter head, a port, a fitting, and a diffuser. The port extends from a portion of the filter head and defines a channel for fluid to flow into or out of the filter head. The fitting first end is attachable to the port and the fitting second end is attachable to a filtration system component. The diffuser is positionable within the channel of the port and comprises an inner surface and an outer surface. The inner surface defines an inner conical hollow region that extends at a nonzero angle between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second end.

An inertial particle separator includes a body with an outer wall, an inlet, an outlet, an inner nozzle, a settling chamber, a serpentine channel, and a filter element. The inlet is disposed on an upstream end of the body. The outlet is disposed on a downstream end of the body. The inner nozzle is disposed radially inward from the outer wall and forms a primary flow passage. The settling chamber is disposed in the body and extends between the outer wall and the inner nozzle. The settling chamber forms a secondary flow passage and is fluidly connected to the inlet and the outlet. The serpentine channel fluidly connects fluidly connects the inlet and the settling chamber and is disposed radially between the outer wall of the body and the inner nozzle. The filter element is disposed in the settling chamber.

The disclosure is directed toward presses which may comprise planar or curved press plates that can be driven toward and away from each other such as via linear reciprocating movement to press filter media sheets as opposed to using rolls. The press plates can create such features as embossments that may have the ridges and grooves, brands, creases or other such features. The press can create pleated packs or individual panels for non-pleated packs. Additionally, a variety of embossed pleat packs, unique shapes, structural components and other pleat packs that may be formed by presses or other methodology are disclosed as well as filter cartridges using such pleat packs.

An air filtering system for an electrical enclosure including at least one filtering element arranged to filter an air flow injected into the inlet of the enclosure by a fan device, the system also including several independent filtering cells Ci, with i ranging from 1 to n and n greater than or equal to 3, each filtering cell Ci having a variable filtering capacity, each filtering cell Ci, with i greater than or equal to 2, is rendered active to filter a part of the air flow when the sum of the filtering capacities of the cells, ranging from C1 to Ci1, drops below a specific threshold.

The objective of this invention is to provide a filter module for coating equipment that can improve the efficiency in removing coating-material mist and preventing the outflow of such coating-material mist to the outside. The filter module of this invention is made of a flammable material and includes an outer box, an eliminator and a baffle plate. Of the outer box, the air A2 containing the coating-material mist flows into the outer box from the outer-box inlet and is discharged from the outer-box outlet. The eliminator is formed by arranging zigzag-shaped eliminator elements in parallel to separate the coating-material mist from the air A2. The baffle plate is formed by arranging baffle-plate elements having an inclined surface for guiding the air A2 in parallel into the inflow-side space S2 of the eliminator, and guides the air A2 that has been introduced from the outer-box inlet to the inflow-side space S2.

A cleaner casing is fitted to a fan casing for covering an air cooling fan for an engine. A cleaner chamber is formed between the fan casing and the cleaner casing. The cleaner chamber accommodates therein a cylindrical filter element. The filter element purifies air which will becomes an intake air for the engine. In an outer periphery of the cleaner chamber, a swirling passage is formed. An air outside the fan casing is captured into the switching passage through a suction opening. The swirling passage allows the air to be passed onto a hollow portion of the filter element after the air has been swirled around the filter element thereby.
