Description
Cut down the number of sparks that reach your collector or cyclone. It breaks up the airflow so sparks cool and go out before they get there.
What you get
- No moving parts, no power
- Works at 1500 to 3500 fpm, best at 3000 fpm
- Mount at least ten duct diameters from the collector and from the source (8 in. duct means at least 80 in.)
- 4 in. to 18 in. sizes include two Quick-Fit clamps joining the sections
- Mild steel with blue powder coat
Before you order
- Quick-Fit clamps are sold separately. Plan on one clamp per component in your order.
- Made in the USA by Nordfab in Thomasville, NC. Nordfab is ISO 9001:2015 and ISO 14001:2015 certified.
When this is not the right part for you
- It is not an explosion isolation device. Nordfab is clear that it does not replace spark detection or explosion isolation. It works alongside them.
