Installed in ducting as part of a dust collection system, the Nordfab Quick-Fit® In-line Spark Trap 2.0 greatly reduces the possibility of fire in cyclones / collectors by decreasing the number of sparks which could reach the cyclone or collector through the ductwork. 

• No moving parts and no power required for operation.

• Minimal pressure loss

• Can quickly and easily be mounted into Quick-Fit ducting systems, or other duct systems with use of a Nordfab adapter, and the trap can easily be removed for cleanout.

• For flanged applications, order our Spark Trap AFL Assembly which includes a Spark Trap and two Angle Flange Adapters.

• Calibration or other assistance from a factory technician is not required.

This is a simple, low-cost tool that can reduce incidents of fire events, reducing costs and disruption and improving safety. System redundancy and complementary measures should be applied.

• Sturdy construction - heavier gauge, powder-coated mild steel

• Available in diameters up to 24"

• Available as an AFL Assembly with angle flange adapters for flanged applications
