Many industrial processes create sparks that when not properly handled lead to an increased likelihood of fire. Our engineered spark arrestor greatly reduces the risk of fire. Micro Air spark arrestors can be mounted into duct work before the dust collector to help mitigate sparks traveling through the system. The spark arrestors work by allowing the air to slow down through the arrestor baffles & help extinguish sparks. These can be made to mount vertical or horizontal in your duct system before your dust collector.
