Our manual smoke exhaust window operates by hand‑driven opening‑closing mechanism without external power wiring. Its straightforward and sturdy framework brings convenient routine inspection and greatly cuts long‑term maintenance expense.

Flexible mounting methods are compatible with diverse roof and curtain‑wall structures.

Ready‑made options are abundant. This smoke vent is widely applied for air circulation and smoke exhausting in small workshops, out‑annex buildings and storage warehouses, and we accept all kinds of small‑to‑medium construction‑project orders.
