Gravity Shutter

Designed for efficient and maintenance-free operation, our gravity shutters automatically open with outgoing airflow and close tightly when the system is off—ensuring effective backflow prevention and improved air quality. Suitable for commercial, industrial, and residential ventilation setups, these shutters are manufactured from high-quality materials that offer durability, corrosion resistance, and long-term performance. Zamzam for Engineering Industries ensures precise fabrication, smooth blade movement, and compliance with international HVAC standards, making our gravity shutters a dependable solution for controlled natural exhaust and system protection.
