Ventilation Bend Pipe Air Duct Air Cooler Evaporative Air Conditioning Ventilation Duct Industrial Evaporative Air Cooler Duct System

Product Description

This industrial evaporative cooler air duct system is a complete set of flame-retardant PP ventilation piping solution, consisting of straight air ducts and large-radius ventilation elbows. It is manufactured from industrial-grade modified flame-retardant polypropylene (PP) with anti-aging additives, reaching UL 94 V-0 flame retardant grade and delivering outstanding corrosion resistance and ultra-long service life. The large-radius elbows adopt hydrodynamically optimized curvature and one-piece molding process, reducing airflow pressure loss by 38%–42% compared with traditional right-angle elbows, effectively eliminating turbulence dead zones and ensuring smooth air transmission. With standardized socket connection and built-in sealing ring, it features reliable airtightness and easy on-site assembly. Widely used for air supply of industrial coolers, workshop ventilation, exhaust emission and greenhouse cooling, it is a durable, safe and cost-effective piping alternative to traditional metal air ducts.

Applicable Locations

Industrial Factory Workshops: Suitable for air supply pipeline layout of industrial evaporative coolers and environmental air conditioners in manufacturing workshops, assembly plants and processing facilities. The large-radius elbows flexibly adapt to complex pipeline routing, and the long service life meets the demand of long-term continuous industrial operation. Agricultural Greenhouses & Livestock Farms: Ideal for cooling ventilation and exhaust systems in vegetable greenhouses, poultry houses and livestock farms. It is resistant to humidity and ammonia corrosion, with a service life far longer than metal air ducts. Commercial & Public Venues: Perfect for fresh air supply and exhaust projects in supermarkets, exhibition halls, gymnasiums and office buildings. Its flame-retardant performance meets fire safety standards for public places, with stable long-term operation. Warehouses & Logistics Centers: Effective for ventilation and cooling pipeline construction in large warehouses and sorting centers. The large-radius elbows adapt to pipeline turning layouts in high-bay warehouses, realizing long-distance low-loss air delivery. Industrial Ventilation & Dust Removal Projects: Applicable to workshop waste gas exhaust, dust collection and corrosive gas discharge pipelines. It has excellent chemical corrosion resistance, and the large-arc design reduces dust accumulation and extends pipeline service life. Centralized Cooling & HVAC Projects: Suitable for pipeline construction of centralized cooler units and commercial HVAC systems. Straight pipes and large elbows can be freely combined to meet complex pipeline routing and long-distance air transmission requirements.

Duct System Parameters

Feature

High Airflow Efficiency: The inner wall adopts smooth mirror polishing process with extremely low friction coefficient. The large-radius elbow is formed in one piece with hydrodynamically optimized curvature, which eliminates turbulence dead zones and reduces static pressure loss by 38%–42% compared with right-angle elbows, ensuring sufficient air volume and stable air pressure at the end of long-distance pipelines. System Compatibility: As pure physical ventilation fittings, they require no independent electronic control system. They are fully compatible with control systems of various industrial air coolers and ventilation units, operating synchronously with the host equipment to maintain stable air delivery performance without additional debugging. Standardized Sealed Connection: Adopts national standard socket structure with built-in high-elastic EPDM sealing ring. Reliable airtight performance is achieved by direct plug-in, avoiding air leakage and ensuring stable ventilation efficiency. Modular Design: Both straight pipes and large elbows are produced in standardized modular structure. They can be freely spliced and combined according to on-site pipeline routing, and straight pipes can be cut to required lengths, adapting to complex on-site pipeline layouts and making disassembly, adjustment and partial replacement very convenient. Advanced Material Technology: Adopts weather-resistant modified PP material added with flame retardant, anti-aging and anti-UV agents. It has excellent flame retardant, corrosion resistant and anti-aging properties, effectively solving the problems of easy rusting and short service life of traditional metal air ducts, and realizing ultra-long service life from the material level.

Advantages

High Ventilation Efficiency: The combination of smooth inner wall and large-curvature elbows greatly reduces airflow resistance and turbulence noise, with minimal air volume attenuation. It supports large-air-volume long-distance transmission with uniform wind speed and no dead corners, and the overall ventilation efficiency is significantly better than traditional iron sheet ducts and right-angle elbow systems. Energy Efficiency: The low wind resistance design effectively reduces the extra load and power consumption of the cooler fan. Compared with aged and corroded traditional metal duct systems, fan energy consumption can be reduced by 15%–20%, saving considerable operating electricity bills in long-term use. Ultra-Long Durability: Weather-resistant modified PP material will not rust, corrode or become brittle. Its service life can reach more than 12 years under normal working conditions, which is 2–3 times that of traditional galvanized iron ducts, greatly reducing pipeline replacement frequency and long-term investment cost. Rapid Installation: The pipe body is lightweight (only about 1/5 of the weight of iron sheet ducts of the same specification). The socket connection requires no welding or flange fixing, and can be cut and spliced on site quickly. The installation efficiency is more than 50% higher than traditional metal air ducts, greatly shortening the project construction period. Low Maintenance Requirements: The smooth inner wall is not easy to accumulate dust and scale, and daily maintenance only requires simple regular cleaning. The pipeline structure is stable with no wearing parts, no anti-rust or anti-corrosion maintenance is needed, and the long-term operation and maintenance cost is extremely low. Versatile Compatibility: The standard caliber is fully compatible with fittings of the same series such as tees and reducers. It is widely compatible with industrial air coolers, environmental air conditioners, fresh air systems, exhaust and dust removal equipment, and is applicable to various ventilation and cooling projects in industrial, agricultural, commercial and storage scenarios.
