Product Overview
The ICEMAC IC-CDF Series Mechanical Constant Flow Damper is specifically engineered for stable and precise airflow management within HVAC supply and exhaust duct systems. Utilizing a self-regulating spring mechanism, it
effectively maintains consistent airflow without requiring electrical or motorized power. Ideal for applications experiencing pressure fluctuations, the IC-CDF ensures reliable and maintenance-free operation, catering to airflow velocities from 2 to 10 m/s across a pressure range of 50–100 Pa.
Key Features
- Durable Construction – Galvanized steel casing with aluminium blades ensures corrosion resistance and mechanical reliability.
- Pressure-Independent Operation – Internal spring mechanism maintains consistent airflow irrespective of system pressure variations.
- Electrical-Free Design – Passive operation without actuators, sensors, or wiring simplifies installation and reduces maintenance.
- Flexible Installation – Suitable for horizontal or vertical mounting in ductwork, with direct screw mounting capability.
Applications
- Restroom and WC Exhaust Lines – Ensures steady extraction rates, maintaining optimal ventilation and odor control.
- Zone Supply Terminals – Balances airflow effectively across multi-zone duct systems, compensating for pressure imbalances.
- Passive Make-Up Air Systems – Provides controlled airflow into sensitive environments such as laboratories and electrical rooms.
- Retrofit and Low-Voltage Projects – Ideal for cost-sensitive or architecturally restricted installations where electrical integration is impractical.
Advantages
- Consistent Airflow Regulation – Precise airflow delivery without fluctuations, ensuring optimal indoor environmental quality.
- Maintenance-Free Operation – Self-regulating design reduces lifecycle costs, eliminating routine servicing.
- Easy and Flexible Installation – Compact and adaptable, allowing rapid integration into various HVAC configurations.
- Cost-Efficient Solution – Eliminates the need for electrical infrastructure, lowering initial and operational expenditures.
