A vehicular exhaust filter comprising a porous substrate having an inlet face and an outlet face with the porous substrate comprising inlet channels extending from the inlet face and outlet channels extending from the outlet face is disclosed. The inlet channels and the outlet channels are separated by a plurality of filter walls having a porous structure. The vehicular exhaust filter is loaded with a refractory powder having a tapped density before loading of less than 0.10 g/cm.sup.3 and the vehicular exhaust filter has a mass loading of the refractory powder of less than 10 g/l.

The invention relates to a dust collector for gaseous fluids and to a method for manufacturing the dust collector. The dust collector includes one or more filtering assemblies (1) that have filtering elements (2). The filtering elements (2) have a tubular extension. They are kept in contact with each other along a direction parallel to their length; the filtering elements (2) enclose, between them, flow channels (3). The method for manufacturing a filtering assembly (1) of the dust collector includes the steps of: permanently deforming a sheet of a filtering material so as to obtain a corrugated sheet (8) with a cross-section defined by repetitions of ′Ω-shaped forms that are connected to each other; and coupling two deformed sheets, so as to keep the straight parts of the ′Ω-shaped forms in contact and to obtain rows of filtering elements (2).

In a device for separating solid particles from liquids and gases in flexible disposable plastic containers, a plurality of filter elements, consisting of flat, elongate support grids with filtrate drain channels and a covering, all-round closed filter medium, are connected to form a filter package and enclosed by a flexible plastic container. This disposable filter system is operated in a pressure vessel and can be compressed there by applying an external pressure in such a way that the residual volume of the suspension is considerably reduced. As a result of the stable design, backwashing of the filter elements is possible, which prevents the build-up of a dense layer of solid particles and can therefore lead to increased filtrate flow. As a result of the completely sealed, sterile filter elements, the increased filter surface area and the resulting high filter efficiency and complete filtration with reduced residual volume shares, this system proves to be a cost-effective filtration device with high flow rates, minimized cleaning costs and short changeover times when changing products.

An adjustable filter track system a filter track having a recess configured to receive a filter, and a frame having a first coupling feature configured to couple to the filter track in a first configuration and a second coupling feature configured to couple to the filter track in a second configuration, where the filter track and the frame are configured to hold the filter in place within the recess, and where the filter track is adjustable between the first configuration and the second configuration to accommodate different thicknesses of the filter.

The RF transmitter assembly can be provided in the first compartment at the inlet of one of the particulate filters, and the RF receiver assembly can be provided at the outlet of said one particulate filter.

A vehicular exhaust filter comprising a porous substrate having an inlet face and an outlet face with the porous substrate comprising inlet channels extending from the inlet face and outlet channels extending from the outlet face is disclosed. The inlet channels and the outlet channels are separated by a plurality of filter walls having a porous structure. The vehicular exhaust filter is loaded with a refractory powder having a tapped density before loading of less than 0.10 g/cm.sup.3 and the vehicular exhaust filter has a mass loading of the refractory powder of less than 10 g/l.
