-Product Model: 803591121
-Product Name: Air Duct Port Top Cover
-Material specifications: High-toughness and weather-resistant engineering material, anti-aging and anti-brittleness, sealed and fitted structure, meeting the ventilation matching standards for engineering machinery.
-Processing technology: one-piece precision injection molding, precise control of port dimensions, smooth edge treatment, and full-body fit and protection performance verification.
The 803591121 air duct port top cover effectively solves problems such as dust and water ingress into ventilation ducts, debris clogging the ducts, turbulent backflow in the ducts, internal dirt accumulation and corrosion, and reduced ventilation efficiency. The product is compatible with XCMG excavators, cranes, aerial work platforms, loaders, and other engineering machinery. It is mainly installed at the ventilation ducts, heat dissipation ducts, and air exchange ports of the equipment, serving to seal and protect the ports, prevent dust and water damage, and block impurities. It stabilizes airflow circulation in the ducts, preventing duct blockage from affecting equipment heat dissipation and ventilation, and ensuring the long-term stable operation of the entire machine’s ventilation and heat dissipation system. This product is made of high-toughness, weather-resistant material, integrally injection molded, with finely finished edges and anti-aging reinforcement treatment. It has passed dustproof, waterproof, pressure-resistant, abrasion-resistant, and high and low temperature weathering durability tests, possessing core advantages such as tight fit, good protection, resistance to cracking, and long-term durability.
