The Model SSN is designed especially to meet the requirements of the latest generations of low emission diesel engines (NRMM stage III A / B, stage IV and V; equivalent US Tier 3 & 4 : Euro 5 and 6 (other harmonised standards) and engines fitted with exhaust treatment devices such as DOC (catalysts) DPF (particulate filters) and SCR (NOx abatement) Post 2014.
Developed with the aid of C.F.D (Computerized Fluid Dynamics) this new range has much lower system flow resistance than conventional spark arrestor designs, enabling them to achieve the low back pressure requirements of high gas flow engines. (At optimum flow rates back pressure is approximately half that of other equivalent models) This smoother, less turbulent internal gas flow reduces the secondary noise regeneration often associated with spark arrestors making them much quieter across the power range.
Exhaust gas flow rates and back pressure limits vary between engine manufacturers. Please consult us with your requirements for further information.

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.
