Services

Comprehensive HVAC Airflow & Safety Solutions

Efficient air distribution and fire protection are critical components of any HVAC system. By integrating Volume Control Dampers (VCD), Fire Dampers (FD), and Variable Air Volume (VAV) systems, Annex AC Trading delivers complete solutions that improve indoor comfort, system efficiency, and building safety.

Volume Control Dampers (VCD)

Precise Airflow Balancing for HVAC Ducting

Volume Control Dampers (VCD) are used to regulate and balance airflow within HVAC duct systems. They allow accurate adjustment of air volume to different zones, ensuring consistent temperature distribution and improved system performance.

Key Benefits of VCD:

  • Accurate airflow regulation and balancing

  • Reduced energy loss and improved efficiency

  • Durable construction for long service life

  • Suitable for manual or motorized operation

  • Compatible with commercial and residential HVAC systems

Fire Dampers (FD)

Essential Fire Protection for HVAC Systems

Fire Dampers (FD) are critical safety components designed to prevent the spread of fire and smoke through HVAC ductwork. Installed at fire-rated wall or floor penetrations, fire dampers automatically close during high temperatures, helping protect occupants and property.

Key Benefits of FD:

  • Automatic activation during fire conditions

  • Limits fire and smoke transmission through ducts

  • Complies with international fire safety standards

  • Strong, fire-rated steel construction

  • Minimal impact on airflow during normal operation

Variable Air Volume (VAV)

Intelligent Airflow Control for Energy Efficiency

Variable Air Volume (VAV) systems provide dynamic airflow control by adjusting the volume of conditioned air supplied to different zones based on demand. This results in lower energy consumption, enhanced comfort, and optimized HVAC system operation.

Key Benefits of VAV Systems:

  • Energy-efficient zone-based airflow control

  • Improved indoor comfort and air quality

  • Reduced operational and maintenance costs

  • Seamless integration with BMS systems

  • Ideal for smart and sustainable buildings
