A PUREX Spark Arrestor is a safety device installed before the fume extractor. Its main function is to intercept, cool, and retain sparks or hot particles before they enter the extraction and filtration system. Spark Arrestors - Purex International
How does it work?
The process can be understood as follows:
Machine/Laser → smoke + dust + sparks → Spark Arrestor → PUREX extractor → filters
The machine generates sparks and hot particles.
In processes such as laser applications, contaminated air can carry hot particles along with smoke and dust.
The air enters the Spark Arrestor.
Before reaching the PUREX extractor, the airflow passes through the arrestor.
The sparks strike internal plates or baffle/striker plates.
PUREX indicates that impact against these plates prevents the sparks from continuing toward the extraction unit. Spark Arrestor 890247 - Purex International
The hot particles lose energy and cool down.
PUREX describes this process as extinguishing hot sparks against the baffle plates, cooling the material. Spark Arrestors - Purex International
The material is collected inside the Spark Arrestor.
The cooled residue accumulates inside the unit instead of continuing toward the extractor. Some sections of the enclosure are removable to make emptying and cleaning easier. Spark Arrestors - Purex International
Why is it important?
From a technical standpoint, the Spark Arrestor creates a physical barrier before filtration.
It does not replace the PUREX filters. Its purpose is different:
-
Spark Arrestor: controls sparks and hot material.
-
Extractor filters: capture contaminants present in the extraction airflow.
-
PUREX specifically states that its Spark Arrestors are designed to prevent sparks from entering the extraction unit.
-
PUREX also designs different Spark Arrestors according to inlet/outlet diameter and airflow requirements, specifically to limit the restriction the device introduces into the system
