Q-Ball E Flameless Venting for Mechanical Conveyors

The Q-Ball® E guarantees safe explosion pressure relief in the operating area. Efficient cooling inside the Q-Ball® E prevents the flames from escaping and eliminates pressure effects because of the explosion. The Q-Ball® E is suitable for flameless venting of mechanical conveyors with low design strength such as elevators.

Explosions with KSt values up to 200 bar × m/s can be handled. The connecting dimensions of the Q-Ball® E perfectly complement the standard sizes of mechanical conveyors such as elevators. This avoids the need for work-intensive adjustments of the flanges.

Due to the low weight of the Q-Ball® E, any reinforcements of the conveyor‘s shaft also become unnecessary. With the newly developed principle of full body flameless venting, the Q-Ball® E ensures maximum relief efficiency. The necessary relief area can thus be reduced to a minimum.



The Q-Ball® E is suitable for low-strength plant components as well as plants at risk of dust explosions such as elevators with KSt values ≤ 200 bar × m/s.

Applications & Industries

  • Aspiration plants
  • Breweries
  • Elevators
  • Filters
  • Conveyors
  • Wood processing
  • Food production
  • Mixers

  • Animal feed production


The flame gases, which can reach temperatures of up to 1,500°C, are cooled extremely efficiently in the special stainless-steel mesh filter inlet developed by REMBE®. This reduces the volume of escaping gas and thus extinguishes the explosion.


  • Maximum venting efficiency through a full body flameless venting
  • Easy maintenance through an integrated inspection opening
  • Integrated signaling for a reliable monitoring
  • Can be utilized flexibly indoors and outdoors
