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.

Precleaner for engine air intake and methods

A composite food storage container combines the advantages of glass and polymer while avoiding their disadvantages. A composite food storage container may include an outer polymer container that is configured to accommodate a glass container within the polymer container. Since the food does not contact the polymer, there are no potential concerns with chemicals leeching into the food. Since the glass is surrounded by the polymer container, the glass is protected from breakage and the composite food storage container does not become too hot to easily and safely handle upon removal from a microwave oven.

An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes pushing the filter element against a pivot region in the housing to release a seal between the filter element and the housing.
