Apparatus and system for uniform sealing force in an air filter assembly

An air filter system comprising:

• a housing comprising a channel having a plurality of incline portions and a plurality of land portions;
• the housing further comprising an opening configured to receive a filter element assembly having a gasket flange;
• a lid configured to cover the opening and coupled with at least one bayonet extending outward from the lid;
• wherein:
• the bayonet comprises a plurality of incline portions and a plurality of land portions, the incline and land portions of the bayonet configured to interface with the incline and land portions of the channel and provide a uniform axial sealing force on the gasket flange;
• the housing further comprises an air intake port and an air outlet port;
• the incline portions have an incline angle of about 10 degrees;
• said bayonet is inserted into said channel along an insertion direction and engages said channel along a series of discrete spaced contact points;
• said contact points lie along and are spaced along a projection line extending at an oblique angle relative to said insertion direction.
