ATEX-A202 and Harmony ATEX-H9 Spark Arresting Silencers are ABS Type Approved in accordance with ABS Rules for Building and Classing Steel Vessel Rules, 2012, 1-1-4/7.7, 1-1-Appendix 3. Product Type Approval Certificate:  12-HS870175-PDA, dated July 5, 2012.

ATEX-A202 Spark Arresting Cylindrical Silencers
The ATEX-A202 series of diesel engine spark arrestors are constructed of heavy duty 316L Stainless Steel that are excellent for use on stationary, marine, and mobile power units in harsh environments.  They are designed for use on the exhaust of internal combustion engines where the potential for fire hazards exists.  Centrifugal force separates solids from the exhaust gas stream where solids are then deposited in an easily accessible cleanout.   With four models, numerous sizes, and Style 1 or Style 2 inlets/outlets available, the ATEX-A202 series can meet a variety of sound attenuation and installation requirements.

ATEX Harmony™ Spark Arresting Disk Silencers
The ATEX Harmony™ H9 series features a space conserving, spark arresting silencer designed for use on exhaust of internal combustion engines, where fire and explosion hazards exist and where ambient noise levels are relatively low.

Centrifugal force separates solids from the exhaust gas stream. Solids are then deposited in an easily accessible cleanout. The low profile design is ideal for engine enclosures, trailers, marine, or any application in which height and/or low radiated heat is critical.
