Legend Spark Trap

Industrial dust collectors are prone to fires without proper spark reduction methods. Cost barriers often prevent installing effective spark arrestors due to suppliers' inability to handle both design and fabrication in-house, resulting in high prices.

US Duct offers top-quality Legend Spark Traps at unbeatable prices. We combine our dust collection and air dynamics expertise with in-house fabrication to maintain high build and performance quality while offering cost savings. Our patented spark trap is both an effective and affordable way to reduce sparks from grinding, welding, and cutting applications.

Innovative Design

Unlike other units that rely on air swirling and require specific installation distances, our patented spark arrestor extinguishes sparks within the chamber by reversing the air flow twice. This design allows installation right at the collector's inlet. Keeping airspeed under ~3500 FPM ensures a pressure drop of no more than 0.8”.
