Introduction
The Warm Air Duct is a high-performance automotive heater duct designed for vehicle HVAC systems. It channels warm air from the engine heater core into the cabin, improving thermal comfort and defrost efficiency during cold weather.
Features
Heat-Resistant Materials
Engineered from EPDM rubber with a working temperature range of approximately -50℃ to +120℃, the duct delivers reliable performance without softening or degradation under heat.
Efficient Construction
Precision molding and leak-proof joint processes minimize air leakage, improving heat transfer efficiency and reducing energy loss.
Smooth Air Flow
The duct features a smooth inner surface that reduces airflow resistance, ensuring stable warm-air delivery throughout the HVAC system.
Parameters
- Diameter: 50-120mm
- Length: 300-1500mm
- Types: rigid plastic, flexible rubber, customized-shaped ducts.
- Materials: heat-resistant EPDM (non-toxic, odorless)
- Manufacturing: precision molding/extrusion and leak-proof joint processing.
- Maintenance: clean interiors annually and check for cracks/loose joints quarterly. When using, avoid sharp objects and do not block outlets.
