Chalwyn spark arrestors are of the quenching type as defined in BS EN 1834-1:2000 clause 5.10.2. In this design the glowing particles emitted from a diesel engine exhaust are repeatedly impacted against internal spark arrestor surfaces to be cooled and broken down before eventual discharge to atmosphere.
