Abstract: A filter assembly is disclosed comprising a filter cartridge, a filter housing end part, and a filter housing main part, said filter housing main part being adapted for receiving said filter cartridge and for being connected to the housing end part by screwing, wherein



said filter housing main part comprises a first longitudinal axis and a main opening, said main opening being defined by a first end portion, said first end portion comprising an upper, interrupted rim and a first threaded portion arranged below said upper rim;
said first end portion comprising a recess arrangement comprising one or more axially extending recesses, said one or more axially extending recesses at least partially interrupting said first threaded portion;
said filter cartridge comprises a second longitudinal axis and a first end cap, said first end cap comprising a central portion and a radial extension arrangement comprising one or more radial extensions extending radially away from said central portion; and
wherein said radial extension arrangement is adapted for being receivable or received by said recess arrangement; and associated cartridges.

Abstract: A vent having a vent housing defining a mounting structure, a first opening between a first end and a second end of the vent housing, a first airflow pathway from the first opening, a second airflow pathway from a second opening, and a draining pathway from the first airflow pathway through the first end of the vent housing. The first airflow pathway has a first segment and a second segment extending in opposite axial directions. An inlet relief valve and an outlet relief valve are arranged in parallel between the first and second airflow pathways. The inlet relief valve opens upon exceeding a first threshold pressure differential of the second relative to the first airflow pathway. The outlet relief valve opens upon exceeding a second pressure differential of the first relative to the second airflow pathway. A filter assembly is disposed in the vent housing across the second airflow pathway.
