Deflagration Arrestors - 6ZA21

Title/Specs Body Size
6ZA21 3/4", 1", 1-1/2", 2"

The Model 6ZA21 in-line deflagration flame arrestor
is a device that can be fitted to the opening of an
enclosure or to the connecting pipe work of a system of
enclosures. Its primary function is to allow the flow
of gases or vapor of flammable liquids through the
enclosure, but prevent the transmission of a flame.
The element inside the housing provides an
extinguishing barrier to the ignited vapor mixture by
absorbing heat from the flame. The Model 6ZA21 is
used as an independent safety system to ensure
explosion protection.
