Round Volume Control Damper
Manufacturing & Industrial
The IGI Round Volume Control Damper (RVCD) delivers a simple, reliable, and costeffective solution for manual or motorized airflow control in standard HVAC round ductwork. The RVCD features a single butterfly blade inside a cylindrical casing, providing smooth proportional flow regulation and positive shutoff. The IGI RVCD can be supplied with a PVC or galvanized steel hand quadrant for manual balancing, or with 24V/230V motorized ON/OFF actuators for BMS-integrated zone control. Galvanized steel is the standard construction; stainless steel (SS304/SS316) and aluminium are available for corrosive or food-industry environments.
Volume Damper
Manufacturing & Industrial
The IGI Volume Control Damper (VCD) delivers a simple, reliable, and cost-effective solution for manual or motorized airflow control in standard rectangular HVAC ductwork. Multiple interlinked blades within a rigid casing provide smooth, proportional airflow regulation across a wide range of duct sizes. The IGI VCD can be supplied with manual control (lockable hand lever) or with 24V/230V motorized ON/OFF actuators for BMS-integrated zone control. Blades are available in opposed or parallel configuration to suit the application. Galvanized steel is the standard construction; stainless steel (SS304/SS316) is available for corrosive environments.
Curtain Type Fire Damper
Manufacturing & Industrial
The IGI Curtain Type Fire Damper (FD-IGI) is a passive fire protection device designed for installation in HVAC ductwork systems. When exposed to elevated temperatures, the UL-listed fusible link melts, releasing the curtain blades which fall by gravity to seal the duct opening, preventing the spread of fire and hot gases between fire compartments.
Backdraft Damper
Manufacturing & Industrial
The IGI BDD operates purely on differential air pressure. When the fan starts and forward airflow pressure exceeds the weight of the blades (or, on the High Pressure model, the counterbalance spring tension), the blades pivot open on their out-of-airstream linkage, allowing air to pass freely. When the fan stops or airflow reverses, the blades fall closed under their own weight, and the overlapping blade-to-jamb profile forms a tight seal that blocks reverse airflow, backdraft, and cross-contamination between connected ducts or fans.
Access Door
Manufacturing & Industrial
The IGI Access Door (ACCD) provides reliable, economical access to internal HVAC ductwork components for servicing and inspection.
Motorized Fire Smoke Damper
Manufacturing & Industrial
The IGI Motorized Fire Smoke Damper (MFSD) is a life-safety device installed in HVAC ductwork to prevent the spread of fire, smoke, and toxic gases between firerated building compartments. Upon detection of smoke or heat, the spring-return actuator automatically drives the damper blades to the fully closed position, maintaining fire-rated separations and protecting escape routes. The IGI MFSD has been tested in accordance with EN 1363-1:2021 and achieves E120 fire integrity — maintaining containment for 120 minutes under standard fire exposure. The unit is supplied with a 24V or 230V motorized spring-return actuator. On power loss or fire alarm signal, the spring mechanism closes the damper without relying on the electrical supply
