Quenchertm; the True In-line Spark Arrester

Quencher Spark Arrestor

Spark Arrestor cools sparks/embers that cause fires and explosions in a dust collector. It isn't just a spark trap.
  • QUENCHER™ in-line spark arrestor device, is easy to apply and use. Most advanced spark suppressor technology available today.
  • Extinguishes and cools sparks / burning embers from welding, grinding, polishing, buffing, belt sanders, furnaces.
  • Prevents fires and explosions in all dust collection and ducted systems.
  • Static device, with no moving parts, requiring no additional dust collection recipient.
  • No water or chemical retardants are injected.
  • Thoroughly mixes stratified air streams.
  • A small investment for safety and big piece of mind
  • NEW! Now available with rolled-edge (for clamp together duct).

How the QUENCHERtm Spark Arrestor works

"...and tested it last night. It was quite amazing. We put through a large continuous stream of sparks from a grinder and viewed it…” Grant Stevens, Polex Ltd.

Laminar flow in ducts (1) creates a hot air envelop (800oF) around the spark/ember (1400oF) and feeds oxygen to the spark, (2) the spark is buoyed up and floats along in the gas stream for 100 feet or more.
The QUENCHER spark arrestor creates extreme turbulence and breaks apart the envelop, strips the oxygen (fuel) away from the burning spark, extinguishing and cooling it. The temperature of the spark is now too low to cause an ignition and fires. The cooled sparks are safely carried along the gas stream to the dust collector.

Spark Arrester applications

Air mixing or air blender devices,  being marketed as spark arresters/coolers, do not create enough turbulence and have gaps in the cells permitting sparks to slip through.

CELL CLEANER / BOOSTER (optional)
To help reduce the issues associated with dust accumulations, an optional CELL CLEANER / BOOSTER device can be installed in front of the Quencher.  This device can be actuated manually or automatically. For more information on this device, ask for our technical bulletin, "Auto Booster – Duct Cleaner”.

AIR MIXER / AIR BLENDING

If we mix two gas streams flowing through well designed transitions that maintain laminar flow, the result is that the gas streams will continue in the duct with little or no mixing of the combined gas streams.

The QUENCHER™ design is such that the whole cross section of the duct produces an effective mixing.
