A connector arrangement () for connecting a first tube () and a second tube () in a detachable manner has a first connector () and a second connector (), wherein both connectors () have a closed circumference. For establishing a connection between the first and second connectors () an internal surface of a first circumferential portion () of the first connector () is arranged on an external surface of a first circumferential portion () of the second connector () and an external surface of a second circumferential portion () of the first connector () is arranged on an internal surface of a second circumferential portion () of the second connector (). An air duct having such a connector arrangement () and connectors for such a connector arrangement () is disclosed.

Fluid duct arrangement and connectors for a fluid duct

An anti-snow module designed for installation into an air filter housing includes a support plate configured for support in the housing. A partition is provided for mounting into the interior of the housing of the air filter. A valve plate is configured to seals the housing of the air filter below a predetermined differential pressure existing between the interior of the housing of the air filter behind the valve plate and the exterior of the housing of the air filter and open when the differential pressure exceeds a predetermined differential pressure value. At least one guide rail is provided on which the valve plate is slideably supported by at least one guide sleeve provided on the valve plate.

An air filtration system for purifying an air stream, such as the intake air for an internal combustion engine, including a system plate ( ), an unfiltered air zone ( ), a filter housing ( ) containing a filter element ( ), and a filtered air zone ( ). The filter element hermetically seals and separates the unfiltered air zone ( ) from the filtered air zone. The unfiltered air zone ( ) is configured by a first half shell ( ), which is connected to the system plate ( ) in a fixed, hermetically sealed manner. The filter housing ( ) is also connected to the system plate in a fixed and sealed manner. The permanent, air-tight connection of the first half shell to the system plate allows the air filtration system to be manufactured in a simpler, more rapid and more cost effective manner by obviating the need for seals and connecting elements, as well as the need to assemble such parts.
