The vent will be opened when pressure inside the protected enclosure exceeds the design threshold, accordingly, reducing the pressure below a dangerous level.

Characteristics:

1. Low investment cost

2. Simple installation

3. Do not install in an enclosed space

4. Not suitable for some hazardous dusts

The vent will be opened when pressure inside the protected enclosure exceeds the design threshold, accordingly, reducing the pressure below a dangerous level without blowing the fire out of the chamber.

Characteristics:

1. High investment cost and larger vent area required than conventional explosion vent

2. Simple installation

3. Can be installed in enclosed spaces

4. Disperse heat and pressure into the internal space when an explosion occurs.

5. Not suitable for some hazardous dusts

The pressure sensor installed in the enclosure will send a signal to the control cabinet when an explosion occurs, accordingly, the control cabinet will affect to the suppressor to spray chemicals or inert gas to extinguish generated fire inside the enclosure.

Characteristics:

1. High investment costs

2. Installation is more complicated

3. Must have regular maintenance and inspection
