A technique facilitates construction of a wire-wrapped screen. A wrapping machine is operated with a sensor, e.g. a camera, positioned adjacent the wrapping machine while wire is wrapped to create the wire-wrapped screen. The sensor is used to obtain data on at least one parameter of the wire-wrapped screen during creation of the wire-wrapped screen. Data is provided to a controller in communication with the wrapping machine to improve the quality of the wire-wrapped screen. For example, data from the images obtained via the camera may be provided to the controller which is configured to determine slot width as the wire is wrapped. The controller is then able to provide feedback in real time to the wrapping machine so as to adjust the wrapping machine for maintaining a desired slot width.

A depth filter with excellent filtration accuracy and pressure resistance performance even for fluids containing high density and high viscosity powder fine particles. A depth filter having a base material layer, a filtration layer, and a skin layer, in that order, wherein: the substrate layer and the skin layer are layers made by a nonwoven fabric being wound and thermally fused; the filtration layer is a laminate in which at least a nonwoven fabric and a net are laminated, being wound twice or more; and the nonwoven fabric contained in the filtration layer contains a mixed-fiber nonwoven fabric containing two or more types of fibers with mutually different average fiber diameters.

A gas generator includes a housing, an ignition device, a combustion chamber filled with a gas generating agent, a gas discharge port configured to discharge combustion gas to an outside, and a filter portion disposed between the combustion chamber and the gas discharge port, formed of a metal material, and configured to filter the combustion gas. The filter portion includes a first filter disposed on a side of the combustion chamber and a second filter disposed on a side of the gas discharge port and facing the first filter. The gas generator is provided with a space that is provided between the first filter and the second filter, so as to include a position where the combustion gas flows and to have a predetermined thickness in a direction of flow of the combustion gas, causing a flow rate of the combustion gas flowing into the second filter to decrease due to absence of the metal material.

Systems and methods of filtering particulate matter from a fluid are provided. In one exemplary embodiment, a system for filtering particulate matter from a liquid comprises a filter having a filter housing, inlet and outlet ports, and compressible filter media with synthetic fibers. Further, the filter media is disposed in the housing between the inlet and outlet ports and is operable to filter particulate matter from the liquid. Also, a pressure difference between the inlet and outlet ports with the filter media disposed in the housing is no more than four pounds per square inch differential. In addition, the system includes a pump that is operationally coupled to the filter and operable to move the liquid through the filter media with a flux rate of at least eighteen gallons per minute per square foot of the filter media while operating at less than one electrical horsepower.

Provided is a cartridge filter using nanofiber composite fiber yarn, the cartridge filter including: a core having a plurality of holes through which a liquid passes; and a filter medium wound around the core to collect an object to be filtered contained in the liquid, wherein the filter medium comprises composite fiber yarn in which a nanofiber web which is produced by accumulating nanofibers produced by an electrospinning method is laminated to a porous nonwoven fabric, to thus provide excellent durability and improved filtration performance.

According to one aspect of the invention, a coalescer cartridge for separating a first fluid from a second fluid includes a pleated filter media portion including a pleated fluid separation layer configured to separate a first fluid from a second fluid, the first fluid forming relatively small droplets of fluid suspended in the second fluid; and a wrap filter media portion downstream of the pleated media portion including a droplet growth layer configured to coalesce the relatively small droplets of the first fluid into relatively larger droplets of the first fluid.
