Explosion venting

An explosion vent is a safety device to protect equipment or technologies against excessive internal, explosion-incurred pressures, by means of pressure relief. An explosion vent will relieve pressure from the instant its opening (or activation) pressure pstat has been exceeded.

The evaluation of an explosion vent's efficiency and its range of application are subject to rules. See the EN 14797.

During normal venting, the explosion is freely discharged, allowing flames to exit the process being protected. When the protected vessel or pipe is located indoors, ducts are generally used to safely convey the explosion outside the building. However, ductwork has disadvantages and may result in decreased venting efficiency. Flameless venting, in combination with explosion vents, can extinguish the flame from the vented explosion without the use of expensive ducting, limitations to equipment location, or more costly explosion protection.

Explosion vents are usually used on:

  • silos and containers
  • dedusting units
  • dryers
  • mills
  • cyclones
  • etc.

Fike explosion vents are high performance protection devices especially designed to provide dynamic nonfragmenting opening when protecting industrial
processing equipment. Fike explosion vents are available in following distinctive types, each offering ideal solutions for specific applications or industries.


Flameless venting

If it is not possible to create safety zone around the equipment protected with explosion vents, it is necessary to use flameless venting systems.

These systems consists of venting panel and flameless vent.

Fike uses 3 types of flameless venting:

  1. Flameless venting with rectangular venting panel
  2. Flameless venting with round venting panel
  3. Flameless venting for elevator - with elevator venting panel
