Abstract: A pressure relief assembly (100) includes a housing (102) including an air passage chamber (104) having a flap barrier (122) surrounding at least one airflow passage. A membrane flap is secured within the air passage chamber. The membrane flap covers the airflow passage(s) in a closed position. A portion of the membrane flap is configured to move off the airflow passage(s) into an open position. A noise-dampening seal (120) formed of a noise-dampening material is proximate to at least a portion of the flap barrier. The noise-dampening seal is configured to reduce noise generated by movement of the membrane flap as the membrane flap moves from the open position to the closed position. The noise-dampening seal provides a sealing interface with the membrane flap in the closed position.

Abstract: A pressure relief assembly includes a main body (100) including at least one air passage chamber defined between one or more outer walls. At least one flap (320) covers at least one air opening within the air passage chamber(s). The outer wall(s) include one or more first latch members (120). A cover (200) includes one or more second latch members (202) that are configured to securely latch to the first latch member(s).
