Spark Arrestors

When operating vehicles in potentially explosive atmospheres, the selection and fitment of a type approved spark arrestor is an important safety and legal requirement. Choosing a high quality, well designed, engineered and constructed product is absolutely critical for potentially dangerous environments.

At Eminox we don’t make compromises! All our spark arrestors have been Type Approved in accordance with EN 1834 parts 1, 2 & 3 to comply with ATEX Directive (European Directive 94/9/EC) requirements. They are all manufactured from 316 stainless steel to resist the possibility of failure through corrosion and are rigorously tested to ensure durability and extremely effective removal of potentially dangerous incandescent material.

You’ll find Eminox spark arrestors in the most demanding of environments in a wide range of industries where flammable vapours, powders and gases exist, including petrochemical, pharmaceutical, paints, adhesives and foods. We supply spark arrested exhaust systems to OEM’s such Terex-Demag; Liebherr and Deutche Grove.

Particulate matter (soot and ash particles) from diesel engines can be heated by the combustion process to incandescent temperatures, capable of igniting flammable gas or dust atmospheres. Eminox spark arrestors remove this danger by two methods:

• The dwell time of the particles within the exhaust system is increased so that much of their energy is dissipated as heat loss before they emerge from the tailpipe.
• The rotating flow causes attrition of the particles so that they are reduced in size, rendering them unable to transport enough energy to ignite the explosive atmosphere.

For safe and correct operation, it is critical that the spark arrestor is designed for use as part of a complete exhaust system. Our engineers design exhaust systems with type approved Spark Arrestors that are within the engine manufacturer's back pressure limits and have the appropriate silencing properties.
