A filtration unit (1) comprising a support (10) arranged to receive a plurality of filter cartridges (11,11′), the support configured to allow a displacement of the cartridges between a working position (70), in which a first filter cartridge (11) is arranged with own inlet/outlet apertures (71′,71″) in communication with a fluid inlet and outlet line portions (7,8), respectively, and at least one standby position (75) configured for receiving a respective second filter cartridge (11′), an exchange mechanism (12) configured for causing the displacement of the cartridges between the at least one standby position and the working position, a differential pressure sensor (80) configured for measuring a pressure drop through first filter cartridge arranged in the working position and for generating a differential pressure signal (286) responsive to the pressure drop, a control unit (90) configured for receiving the differential pressure signal (86) and for providing an actuation signal (287) of the exchange mechanism, a program means resident in the control unit (90) and configured for generating the actuation signal (287) when the differential pressure signal indicates a pressure drop value exceeding a predetermined lower threshold value. This way, it is possible to arrange a clean filter cartridge in the at least one standby position, ready to be displaced to the working position in replacement of first filter cartridge, and the at least one second clean filter cartridge is transferred to the working position upon exceeding the differential pressure threshold value, remarkably limiting filter maintenance time and costs in a complex fluid distribution network.

A method for controlling display of information on a display device includes storing information corresponding to a broadcast program guide. When a signal is received based on activation of a specific key while the first broadcast program is displayed on a screen, information on the first broadcast program and information on a second program to be broadcast after the first broadcast program is detected. The first broadcast program is then displayed in a first region of the screen simultaneously with the information on the first broadcast program and the information on the second broadcast program in a second region of the screen.

The present disclosure relates to a tumble dryer (1) with a filter arrangement (12) located in a tumble dryer process air flow (21) for removing lint from process air leaving tumble dryer drum. The filter arrangement comprises a first coarse-mesh filter (25) and a second fine filter (27). A first sensor (41) detects a correct positioning of the first filter in the tumble dryer, and a second sensor (33) detects a pressure drop over a process air flow path comprising the second filter. A control arrangement (45) is configured to initiate a disabling operation which disables the fan arrangement (12), if the first filter is not correctly positioned in the tumble dryer or if the pressure drop over the second filter exceeds a predetermined threshold value.

A filter element assembly includes a filter body and an auxiliary filter. The filter body includes a sidewall around a hollow core. Further the filter body and auxiliary filter are both received and held on a support including a base and a cage.

A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally comprises z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.

A dust collector diaphragm valve capable of performing manual emergency operation according to the present invention is configured to perform control so that the internal equal pressure of the diaphragm valve can be broken due to an internal pressure drop attributable to an instantaneous air discharge occurring whenever an emergency operation switch is manually pressed when a pulse operation signal or solenoid valve used to operate the diaphragm valve fails, and thus a rubber plate installed between the body and cover of the diaphragm valve can be turned (moved forward) after being instantaneously moved backward. Accordingly, dedusting work can be manually performed according to the determination of a manager, and thus the dust collector diaphragm valve can prevent an emergency shutdown during the operation of a dust collector and can also prevent a filter from reaching a limit differential pressure, thereby preventing the lifespan of the filter from being shortened.
