Spark Arrestor

ISTIQ Spark Arrestors are designed for exhaust systems that require reducing the risk of sparks or hot particles being discharged from engines, generators, boilers, process equipment, and other combustion-related systems. They are commonly used in diesel generator exhaust systems, industrial plants, oil and gas facilities, factories, utilities, and sites where exhaust discharge safety is an important consideration.

A spark arrestor is not the same as an exhaust silencer. Its main function is to help trap or separate sparks and burning particles from the exhaust stream before they leave the system. In many installations, the spark arrestor may be used together with an exhaust silencer to provide both spark control and exhaust noise reduction. This is especially useful for generator sets and industrial engines installed near sensitive, flammable, or high-risk areas.

The design of a spark arrestor must consider exhaust gas flow, temperature, velocity, pressure drop, connection size, material selection, maintenance access, drainage, cleaning requirements, and installation position. If the unit is poorly selected or not properly maintained, it may create excessive restriction in the exhaust system or lose effectiveness over time.

Depending on the application, ISTIQ Spark Arrestors can be designed with a suitable casing, internal separation elements, flanged connections, drain points, inspection access, lifting provisions, and high-temperature materials or coatings. For genset and engine applications, proper coordination with the exhaust piping, silencer, expansion joint, support structure, and discharge stack is important to ensure the system remains safe, durable, and practical to service.

For clients who need a safer, more complete exhaust system, ISTIQ Spark Arrestors provide a practical engineering solution that supports exhaust safety, equipment protection, and responsible site operations.
