Abstract: A precleaner for engine air filtration includes a housing, separator tubes for inducing cyclonic airflow, and channel arrangements in airflow communication with the separator tubes to channel airflow and particulates toward a dust outlet arrangement.

Abstract: The present disclosure relates to filter assemblies. The features described and characterized are typically applied in gas (for example, air) cleaner assemblies. A typical use is in air cleaner assemblies for vehicles or other equipment. The techniques described relate, at least in part, to provision of assemblies with preferred configurations for convenient servicing and operation, while ensuring a proper cartridge is appropriately positioned, oriented and secured for use. Many of the techniques relate to arrangements in which features at opposite ends of a housing and/or cartridge are eccentrically positioned as described.

Abstract: A pre-cleaner tube assembly includes an inlet tube having an inlet tube wall surrounding an interior volume and first and second open, opposite ends. A vane arrangement is oriented within the inlet tube wall adjacent to the first open end. The inlet tube wall defines a slot adjacent to the second open end. An outlet tube has an outlet tube wall surrounding an interior volume, an open entrance end, and an opposite open exit end. The outlet tube wall has an exterior and an interior. The exterior of the outlet tube wall has a ramp extending upward as the ramp extends from a region adjacent to the entrance end toward a remaining portion of the outlet tube wall. The outlet tube is oriented in the inlet tube wall interior volume such that the entrance end and over 50% of a length of the outlet wall is within the inlet tube wall interior volume.

Abstract: A silencer for a ventilation system, for example a gas turbine air intake system, includes first and second body sections spaced from each other to define a gas flow path therebetween. Methods of attenuating noise from a gas turbine air intake includes directing air from a dirty air plenum of a gas turbine air intake system through an air flow path defined by first and second body sections.
