1. Core Classification of Flexible Duct
Flexible ducts are engineered with different materials, functional designs, and safety ratings to meet diverse industry demands. Below are our full product lines with unique advantages for global market needs:
1.1 Aluminum Flexible Duct
Aluminum flexible duct is the most classic and widely used basic type of air duct. Made of high-purity aluminum foil with spiral steel wire reinforcement, it boasts lightweight, high flexibility, and excellent heat dissipation performance. It can be freely bent and twisted to adapt to narrow ceiling gaps, corner turns, and irregular installation spaces, solving the layout limitations of rigid ducts perfectly.
Key Features & Applications: Cost-effective, easy to cut and install, corrosion-resistant, and recyclable. It is ideal for residential ventilation, household HVAC systems, commercial building fresh air systems, and general exhaust ventilation projects. As a cost-standard product, it is the top choice for bulk wholesale and conventional construction projects worldwide.
1.2 Insulated Flexible Duct
Insulated flexible duct is upgraded based on standard aluminum ducts, equipped with a thick layer of thermal insulation material (polyester or glass wool) inside and a protective outer jacket. This layered structure effectively prevents cold and heat loss, avoids condensation water generation, and reduces energy consumption of the air conditioning system.
Key Features & Applications: Excellent thermal insulation, anti-condensation, energy-saving. It is specially designed for central air conditioning systems, commercial office buildings, shopping malls, hotel HVAC projects, and all scenarios requiring constant temperature air supply. It significantly improves air conditioning efficiency and reduces long-term energy bills for end users.
1.3 PVC Flexible Duct
PVC flexible duct is manufactured from high-quality PVC synthetic material with high-tensile spiral reinforcement. Compared with aluminum ducts, it has better waterproof, dustproof, and anti-aging properties, with strong toughness and not easy to crack or deform in low-temperature environments.
Key Features & Applications: Wear-resistant, waterproof, dust-proof, low-temperature resistant, and ultra-cost-effective. It is widely used for ordinary fresh air ventilation, equipment exhaust, kitchen and bathroom ventilation, and temporary engineering ventilation. It is a practical and economical option for medium and low-end ventilation projects.
1.4 Acoustic Flexible Duct
Noise pollution in HVAC systems is a common pain point for commercial and high-end construction projects. Acoustic flexible duct is professionally designed for noise reduction, adopting internal sound-absorbing cotton and multi-layer mute structure, which can effectively absorb airflow noise and vibration noise generated by fan operation.
Key Features & Applications: Superior sound insulation and noise reduction, stable air delivery, no vibration resonance. It is widely applied in high-end office buildings, hospitals, schools, conference rooms, theaters, and residential luxury renovation projects where quiet indoor environments are strictly required.
1.5 Fire Rated Flexible Duct
Safety is the top priority for building ventilation systems. Fire rated flexible ducts are produced with flame-retardant and fire-proof materials, passing international fire safety standards. They feature self-extinguishing, flame retardant, smoke suppression, and high-temperature resistance, which can prevent fire spread through ventilation pipelines in case of fire accidents.
Key Features & Applications: Fireproof, high-temperature resistant, smoke-free, safety compliant. It is a mandatory safety component for high-rise buildings, shopping malls, subway stations, industrial workshops, public infrastructure, and all fire-standard restricted projects, fully meeting global construction safety codes.
1.6 Industrial Flexible Duct (New Upgraded Series ⭐)
To meet the growing demand for heavy-duty ventilation in industrial scenarios, we have newly launched a professional Industrial Flexible Duct series, tailored for harsh industrial environments with high wear resistance, high pressure resistance, corrosion resistance, and long service life. It breaks the limitations of conventional civil ducts and is suitable for all kinds of industrial air delivery, exhaust, dust removal, and material conveying scenarios.
1.6.1 PU Steel Wire Hose
PU steel wire hose is a heavy-duty industrial duct made of high-performance PU material and high-strength steel wire spiral reinforcement. It features ultra-high wear resistance, pressure resistance, tensile resistance, and anti-corrosion, with smooth inner wall to reduce airflow and material conveying resistance. It can withstand harsh conditions such as high wind pressure, dust erosion, and chemical gas corrosion.
Core Applications: Industrial dust removal, factory exhaust, woodworking dust suction, chemical gas conveying, grain and particle material transmission, mechanical equipment ventilation, and other heavy industrial scenarios.
1.6.2 TPU Hose (Expandable Custom Series)
TPU hose is an upgraded version of PU hose, adopting imported TPU thermoplastic polyurethane material. It has better elasticity, low-temperature resistance, oil resistance, and anti-aging performance, with higher flexibility and fold resistance. This series supports customized caliber, length, pressure resistance grade, and special functional modifications to meet personalized industrial project needs.
Core Applications: Precision machinery ventilation, automobile industry exhaust, chemical plant corrosive gas transportation, low-temperature environment ventilation, flexible pipeline connection for automated equipment, and other high-precision and high-standard industrial scenarios.
1.7 Flexible Duct Connector
Flexible duct connectors are essential supporting accessories for the entire duct system, matching all types of flexible ducts. Made of high-quality durable materials, they feature tight connection, no air leakage, easy disassembly and assembly, and good sealing and shock absorption effects. They can effectively avoid air leakage, pipeline shaking, and noise problems at the duct connection interface, ensuring the stable and efficient operation of the entire ventilation system.
Suitable for all HVAC duct splicing, industrial pipeline connection, and engineering system renovation scenarios, it is a necessary supporting product for one-stop duct system procurement.
