Description
- This is a manual inline blast gate designed for 100mm (4 inch) exhaust and ventilation hoses. It installs between two hoses or duct sections and uses a sliding gate to quickly open or completely block airflow.
- I personally use this to close off my window exhaust vent when my 3D printer isn’t running, preventing cold air, heat loss, smells, or outside drafts from coming back into the room. It’s a simple, effective solution for any vent that doesn’t need to be open all the time.

- Inline design – connects two hoses or ducts together

- No electronics or moving parts beyond the slide
