Pressure relief assembly

A pressure relief assembly comprising:

• a frame comprising a coupling structure, a valve mounting surface, and a valve opening within the valve mounting surface, the pressure relief assembly having a first axial end, a second axial end, and a valve airflow pathway extending from the first axial end through the second axial end through the valve opening;
• a valve body sealably disposed on the valve mounting surface across the valve opening, whereby the valve airflow pathway is obstructed;
• and
• a first spring-loaded detent releasably securing the valve body to the frame, wherein the first spring-loaded detent is configured to release the valve body from the frame upon a minimum pressure differential across the valve opening,
• wherein the valve body is configured to be clear of the valve airflow pathway upon the minimum pressure differential across the valve opening.

• wherein the first spring-loaded detent comprises a detent housing having a first end and a second end, a compression spring disposed in the detent housing, the compression spring extending from the first end towards the second end;
• and a detent engagement surface translatably disposed in the detent housing, wherein the compression spring is compressibly disposed between the detent engagement surface and the first end of the detent housing.
