  • Method for leak testing air filters
    Patent number: 4646558
    Abstract: A HEPA-type, downflow air filter module is disclosed, having a damper supported upon a hollow tube for adjustable movement relative to an opening through which air enters the enclosed chamber or plenum above the filter media. The hollow damper support tube is axially aligned with a passageway between upstream and downstream sides of the center board which conventionally separates the media core into two halves in such filter modules. The passageway is normally sealed by a plug which may be removed from the downstream side of the module for measuring and adjusting air flow into the module, as controlled by the position of the damper which may be adjusted while air flow is being measured.
    Type: Grant
