Fan coil units (FCUs) and ventilation fans are the most widely used terminal equipment in commercial and residential HVAC systems. After long-term continuous operation, fan blades, aluminum fins, coil surfaces, and internal wind cavities easily accumulate dust, grease, pollen, mold, and sticky dirt. This buildup causes weak cooling/heating capacity, low
Noise pollution is one of the most common issues in modern HVAC systems. Fan vibration, airflow turbulence, and duct resonance often generate persistent humming and buzzing noise, affecting indoor comfort in residential, commercial, and public buildings. Traditional rigid ducts and standard flexible ducts can hardly solve airborne and structure-borne noise
Commercial kitchen exhaust ducts, industrial ventilation pipework, and long-running HVAC duct systems inevitably accumulate thick layered grease, carbonized oil sludge, and sticky dust deposits over time. Traditional liquid cleaners flow off quickly and fail to adhere to duct inner walls, resulting in incomplete cleaning and residual grease buildup. Foam Duct
In residential ventilation, commercial HVAC systems, and light industrial exhaust projects, flexible ductwork is essential for solving complex piping layouts, short-distance air delivery, and equipment connection transitions. Among all flexible duct types, PVC Flexible Duct stands out as the most cost-effective, lightweight, and highly adaptable solution. Made of high-toughness PVC
In modern commercial ventilation, central air conditioning systems, and industrial HVAC projects, ordinary flexible ducts often suffer from cooling/heating loss, condensation dripping, and low thermal efficiency. As a premium integrated HVAC duct solution, Insulated Flexible Ducts combine flexible air delivery, professional thermal insulation, and anti-condensation performance in one product. It
In metal processing, HVAC component manufacturing, mechanical maintenance, and industrial workshop operations, metal workpieces and equipment are constantly exposed to heavy grease, machining oil, dust sludge, and humid environments. These contaminants not only affect surface appearance and assembly accuracy but also cause metal oxidation, rust formation, and shortened equipment service
