Spark Arrestor

A spark arrestor can be defined as an element that intercepts flammable debris from combustion sources in order to prevent fires. Early spark arrestors, commonly designed as spiral shaped cones, were employed in steam locomotives to separate embers from the exhaust through centrifugal force. Read More... Spark Arrestor

The True In-line Spark Arrestor / Suppressor / Trap Spark Arrestor cools sparks/embers that cause fires and explosions in a dust collector. It isn't just a spark trap! Most advanced spark suppressor technology available on the market today. In 2003, QAM re-engineered a forgotten technology discovered and used (in the USA), in the 1960's, for mist eliminators, wet scrubbers and spark traps (in Japan). Extinguishes and cools sparks / burning embers from welding fumes, plasma cutting table, grinding, polishing, buffing, belt sanders, furnaces, biomass boilers, and any application which creates a possible spark hazard. Prevents fires and explosions in all dust collection and ducted systems. Static device, with no moving parts, requiring no additional dust collection recipient. No water or chemical retardants are injected. In-line spark arrestor device, is easy to apply, install, use and maintain. Available in any duct size and airflow required, we can custom design your spark arrestor to fit any of your facility's requirements. Rolled-edge (for clamp together duct) option. Stainless steel, high abrasion, high temperature (up to 2000 degF)optional construction.

Spark Arrestor List

When it comes to engines, there are two main types of arrestors- centrifugal and screen. Centrifugal spark arrestors use baffles or stationary vanes to catch flammable debris using centrifugal force. These are commonly used in agricultural and construction equipment like combines, bulldozers, and tractors.

Screen arrestors, on the other hand, are much more simple and used in smaller engines and also often in the tops of flues on buildings. These consist of a metal mesh that traps large particles and prevents them from leaving the exhaust system. In addition to their use with engines, spark arrestors are also used in conjunction with dust collecting systems in the industrial setting.

These are effective in preventing fires and explosions by extinguishing, cooling, and rerouting sparks and burning embers that are caught in flow of dust collection and ductile systems.

These are essential in settings where grinding, plasma/laser cutting, welding, torch cutting, and flame spray occur. There are a few different designs of spark arrestors and manufacturers are often producing newer and more effective models. Some of the newest technologies are designed to channel flammable debris in a circulating manner, which allows the embers and sparks to lose more energy before they are deposited in a safe location.
