Abstract: A tubular filter arrangement (1000) comprising a tubular filter element (100) and a tubular air pulse distributor (300) is provided. The filter element comprises a tubular pleated filter media (106) having an initially circular cross section, and a cage structure (120) and which along an exterior envelope surface thereof is arranged to support the pleated filter media. The exterior envelope surface of the cage structure, defines a first and a second set of two opposing wall portions (123, 124). In a condition when the pleated filter media is arranged to encircle the exterior envelope surface of the cage structure, an inner wall (107) of the pleated filter media is elastically deformed to conform to the exterior envelope surface of the cage structure (120). The tubular air pulse distributor comprises a locking member (303) configured to allow the tubular air pulse distributor to lockingly engage the tubular filter element.

Abstract: A connector system includes an adaptor with a magnetic target surface, and a nozzle that is configured to be connected to the magnetic target surface of the adaptor by a magnetic coupling. The nozzle has a housing having an inlet end and an outlet end, and a throughgoing channel having an axial extension therebetween. The housing includes one or more magnets that are arranged at the inlet end and configured to direct or indirect engage the magnetic target surface in a condition when the nozzle is connected to the adaptor. Further, the housing includes one or more air vents that are arranged at the outlet end and which have an axial extension being radially displaced in view of the axial extension of the throughgoing channel.

Abstract: A ventilation system is disclosed comprising a main duct (101) connected to at least one motorized fan (105), and further connected to at least one workplace (Wa; Wb; Wc) via a local duct arrangement (102a; 102b; 102c). The local duct arrangement comprises an asymmetrical bend duct section (106). A first and a second pressure sensor (120,122) are arranged on different positions on the outside of the bend duct section and in communication with the interior thereof. The pressure sensors are configured to communicate with a control computer (200) configured to determine a pressure difference between the positions of the sensors and to control the speed of the fan. Further, a method of operating a ventilation system is disclosed and also an asymmetric bend duct section and the use thereof.

Abstract: The present invention relates to a back pressure flap valve arrangement (1) comprising a housing (2) having an inlet opening (3) and an outlet opening (4). A flap (7) is pivotably hinged about a shaft (8) extending transverse a flow direction through the housing (2). A lever (10) is rigidly connectable to the shaft (8) and forming an angle thereto. The lever (10) has a stop face (11) arranged at a distance from the connection between the lever (10) and the shaft (8) such that the stop face (11) is arranged to move along an arc shaped path when the flap (7) pivots about said shaft (8). The arrangement (1) further comprises a stopper (12) having a slot (14) having an open end (16) and a longitudinal extension along a center line (CL) of the slot (14). The stopper has a first deformation zone (19) along a first side of the slot and a second deformation zone (20) along a second side of the slot, opposite the first side of the slot.

Abstract: The invention relates to an evaporator. The evaporator may include a drum. The drum may have a first portion and a second portion. The drum may include a product inlet positioned at the first portion of the drum, a product outlet positioned at the second portion of the drum, a vapor outlet, and an agitator. The evaporator may have a heating jacket and/or a product supply pipe. The heating jacket may be configured to surround the drum and/or to heat the product in the drum. The product supply pipe may be positioned outside the drum and/or may extend from the second portion of the drum to the product inlet positioned at the first portion of the drum. The product supply pipe may be in direct contact with the heating jacket.

Abstract: A back pressure flap valve arrangement is disclosed. The arrangement comprises a housing (101) having an inlet opening (102) and an outlet opening (103) adapted for connection of the housing (101) to a ducting (200), and at least one side wall (104) extending along a flow direction through the housing (101) from the inlet opening (102) to the outlet opening (103). A flap (1) is pivotably hinged about a shaft (5) thereby being movable between an open position and a closed position, said shaft (5) extending transverse the flow direction. At least one locking device (10) is fixedly mounted to the side wall (104) and comprises a locking pin (14) and a stopping member (12). The locking pin (14) is movable between a retracted position and a locking position, and being biased towards said locking position.
