Air filter having a low internal pressure drop
A disposable air filter is described including a filter element (24) formed from a stacked plurality of annular disks (25). The disks (25) are formed from a sorptive material and expand upon absorption of oil or water droplets. The disks (25) are slightly compressed by a movable baffle (28). The baf...

Zusammenfassung: | A disposable air filter is described including a filter element (24) formed from a stacked plurality of annular disks (25). The disks (25) are formed from a sorptive material and expand upon absorption of oil or water droplets. The disks (25) are slightly compressed by a movable baffle (28). The baffle (28) floats upon a stream of air entering the filter and directs the air radially through the filter element (24). The air flows between and through the disks (25) with a resulting low pressure drop across the filter. As the disks (25) expand, the baffle (28) shifts axially within a filter housing (11) to maintain the pressure drop across the filter element. |
