Gravity Shutter with Counter Weight

Engineered for systems requiring controlled exhaust and dependable closure, our gravity shutters with counter weight ensure smooth blade operation and secure shutoff when airflow stops. The added counter weight mechanism enhances sensitivity and closing accuracy, preventing backflow, dust ingress, and unwanted outdoor air from entering the ventilation system. Ideal for industrial facilities, commercial buildings, mechanical rooms, and environments with variable air pressures, these shutters offer strong durability, corrosion resistance, and long-term performance. Manufactured with precision and compliant with international HVAC standards, Zamzam for Engineering Industries guarantees stable operation, easy installation, and superior protection for all ventilation setups.
