Delta3™ Sparkout Spark Arrestor


Sparks are a natural byproduct of welding, grinding and metal cutting-but if they are left uncontrolled, the resulting fires can have devastating consequences. Now you can protect your workers, equipment and facilities with the most advanced and efficient inline spark arrestance system available on the market today.

The Delta3™ inline spark arrestor is built on groundbreaking technology that uses centrifugal force to kill sparks before they have a chance to ignite. By stopping sparks right at the source, Delta3 creates a safer work environment and vastly reduces the risk of avoidable work accidents. And our innovative design will help you keep productivity high, operating costs low, and maintenance costs to a minimum.

How? Our Delta3 units are self cleaning to minimize maintenance costs and system downtime. They also provide superior air flow compared to traditional spark arrestance systems, which lowers energy costs and maximizes the life of your filters. Delta3 delivers:

  • Excellent spark control
  • Self-cleaning operation
  • Low pressure drop

How it Works

ACentrifugal action drives sparks and embers against the outer wall of the device, stripping off the thermal envelope that surrounds them so that they are rapidly cooled and extinguished.

BHigh air velocities are maintained on the surfaces inside the device, eliminating particulate deposits so the unit is constantly cleaning itself.

CInternal air turbulence is minimal, which lowers the restriction to airflow. This reduces the energy required for operation and improves filter life.


Delta3 stamped out the competition in comparative tests. It’s the only technology in our comparative testing that extinguished 99.9% of sparks for welding, grinding and plasma cutting applications.

Fire Prevention

Fires require three main elements in order to ignite or be sustained:

  • Fuel Source
  • Oxygen
  • Heat or Ignition Source

In a Fume Collection system servicing a welding or metal cutting process, these three elements come together when a hot spark makes its way into the collector and comes in contact with a filter cartridge. Fume Collection systems move air at high speed and therefore provide an excellent source of Oxygen, so it is critical to employ a system that effectively kills the sparks (the Ignition source) before they reach the dust particulate (the Fuel).
