Abstract
A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally includes z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.
Claims27
An air filter cartridge comprising:
- (a) a z-filter media construction having an inlet flow face and an outlet flow face and an outer perimeter with a configuration;
- (i) the z-filter media construction defining a non-cylindrical receiving socket in at least one of the inlet flow face and the outlet flow face;
- (b) a non-cylindrical core arrangement within the z-filter media construction;
- the core arrangement having opposing walls lining said receiving socket;
- (i) said opposing walls defining at least one receiver pocket;
- and
- (c) a seal member mounted to the z-filter media construction;
- (i) the seal member being within 10 mm of the inlet flow face;
- (ii) the seal member being mounted along the outer perimeter of the z-filter media construction to have a same configuration as the z-filter media construction.
An air filter cartridge comprising:
- (a) a filter media construction including an inlet flow face, an outlet flow face, and an outer perimeter with a configuration;
- a plurality of inlet flow flutes open at the inlet flow face and closed to passage of air therefrom adjacent the outlet flow face;
- and a plurality of outlet flow flutes closed adjacent the inlet flow face and open to outlet flow at the outlet flow face;
- (i) the configuration of the outer perimeter having opposite rounded end sections joined by first and second sections;
- (ii) the media construction defining a non-cylindrical receiving socket in at least one of the inlet flow face and the outlet flow face;
- (b) a non-cylindrical core arrangement within the media construction;
- the core arrangement having opposing walls lining said receiving socket;
- (i) said opposing walls defining at least one receiver pocket;
- and
- (c) a seal arrangement mounted to the outer perimeter of the filter media construction to have a same configuration as the filter media construction.
