Dongfeng KL truck spare parts Warm air channel 8102055060-C3100

Built as a key component for efficient warm air distribution, this channel features an aerodynamically optimized design to maximize heating performance. The internal surface is smooth and burr-free, with a streamlined structure that minimizes airflow resistance—reducing pressure loss by 35% compared to aftermarket channels. It has a 180mm×150mm rectangular cross-section that delivers a maximum airflow rate of 300m³/h, ensuring the cab (volume 8m³) reaches a comfortable 20℃ from -20℃ in just 8 minutes. The 3-way air outlets (dashboard, footwell, and defrost) are proportionally designed, with 40% of airflow directed to the windshield for fast defogging and 60% distributed to the driver/passenger areas. A built-in adjustable damper allows precise airflow control for personalized comfort

Engineered to withstand high-temperature airflow and minimize heat loss, the 8102055060-C3100 channel adopts a dual-layer composite structure. The inner layer is made of heat-resistant PP (polypropylene) with a continuous operating temperature of 120℃—resisting deformation from hot air (up to 90℃) from the heater core. The outer layer is wrapped in 10mm-thick glass wool insulation, which reduces heat loss by 60% and prevents the outer surface from becoming too hot (touch temperature ≤45℃), avoiding burns and protecting adjacent plastic components. The insulation also has sound-absorbing properties, reducing blower noise by 20dB (from 65dB to 45dB) for a quieter cab environment. This design ensures more warm air reaches the cab instead of being wasted as radiant heat

Optimized to maintain performance in dusty and high-vibration truck cabs, the warm air channel integrates practical protective features. The air inlet is equipped with a fine-mesh filter (50μm pore size) that blocks dust, debris, and hair from entering the channel and clogging the heater core—extending the core’s service life by 40%. The snap-fit connections between channel segments use EPDM rubber gaskets, creating a tight seal that prevents warm air leakage and dust ingress. The PP inner layer undergoes scratch-resistant treatment, withstanding minor impacts from tools or maintenance operations without cracking. The channel also passes 200,000-cycle vibration testing (10-500Hz) without loosening, ensuring stable performance on rough roads

This warm air channel is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled modular structure (main channel + branch outlets + filter + mounting clips) allows a single technician to complete replacement in 45 minutes—no adhesive or specialized tools needed, as the clips lock securely into the cab’s prefabricated slots. The OE-compatible design eliminates air leakage issues common with aftermarket channels, which often reduce heating efficiency and increase fuel consumption (by up to 3% due to longer heater operation). The durable materials and filter extend service life to ≥500,000km—three times that of low-quality alternatives—reducing replacement frequency. Backed by a 2-year/250,000km Dongfeng warranty, it provides reliable heating performance and predictable maintenance expenses for fleet operations
