EXPLOSION VENTS 

The following only applies to AAF-supplied explosion vents. Additional and/or 

different steps, equipment, etc. may be needed for vents and other equipment not 

supplied by AAF. Further, the following is a non-exhaustive list of 

recommendations, and users must carefully read, among other things, the 

manufacturer’s explosion vent guide for further instructions.  

 

10.1

 

Installation of the Explosion Vent 

If an explosion vent is ordered with the FabriPulse M, the explosion vent is 

shipped separately from the collector. Ensure no damage has been done to the 

explosion vent during shipping or handling.  

 

The FabriPulse M will have a frame constructed as part of the unit where the 

explosion vent is mounted. The number of explosion vents and location of the 

explosion vent will be detailed on the collector drawing.  

 

10.2

 

Assembly 

Ensure no damage has been done to the explosion vent during shipping or 

handling. The FabriPulse M will have a frame constructed as part of the unit where 

the explosion vent is mounted. The number of explosion vents and location of the 

explosion vent will be detailed on the collector drawing.  

 

Gripping the opposite sides, carefully remove the  explosion vent from the 

crate that it was shipped. Avoid excessive flexure of the explosion vent while 

handling.  

 

CAUTION: The edges of the explosion vent can be sharp. 

 

CAUTION: Incorrect installation of the explosion vent can cause the panel 

to not open at the rated burst pressure.   

 

Place the explosion vent over the protruding bolt holes of the frame. Make 

certain the dome is protruding outwards. Install the outlet frame.  

 

Install bolts and nuts and tighten to  20-25 ft-lbs per manufacturer’s 

recommendation.
