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

Product Description

This industrial flame-retardant PP straight air duct is a specialized air delivery pipeline designed for industrial evaporative coolers, central air conditioning and ventilation exhaust systems. Made of weather-resistant modified polypropylene (PP) with flame-retardant formulation and anti-aging additives, it features reliable fire safety, excellent corrosion resistance and ultra-long service life. The hydrodynamically optimized smooth inner wall ensures low airflow resistance and unobstructed air transmission, while the standardized socket connection structure delivers reliable sealing performance and easy on-site assembly. Widely used for air supply and exhaust in factories, greenhouses, commercial venues and warehouses, it effectively solves the problems of easy rusting, short service life and high wind resistance of traditional metal air ducts, serving as a durable, safe and cost-effective piping solution for industrial ventilation and cooling systems.

Applicable Locations

Industrial Factory Workshops: Suitable for air supply pipeline layout of industrial evaporative coolers and cooling units in manufacturing workshops, assembly plants and processing facilities, with long service life to adapt to long-term continuous industrial operation. Agricultural Greenhouses & Livestock Farms: Ideal for ventilation, cooling and exhaust systems in vegetable greenhouses, poultry houses and livestock farms. Its corrosion and aging resistance adapts to humid and ammonia-containing farming environments, with far longer service life than metal ducts. Commercial & Public Venues: Perfect for fresh air supply and exhaust projects in supermarkets, exhibition halls, gymnasiums and office buildings. The flame-retardant performance meets public place fire safety standards, with stable long-term operation. Warehouses & Logistics Centers: Effective for ventilation and cooling pipeline construction in large warehouses, sorting centers and logistics parks, providing durable long-cycle air delivery solutions for large storage spaces. Industrial Exhaust & Dust Removal Systems: Applicable to workshop waste gas exhaust, dust collection and corrosive gas discharge pipelines. Its excellent chemical corrosion resistance ensures stable operation even under harsh exhaust conditions, with a long service cycle. Centralized Cooling & HVAC Projects: Suitable for pipeline construction of centralized cooler groups and commercial HVAC systems. Standardized straight pipes can be freely cut and matched to meet the needs of complex pipeline routing and long-distance air transmission.

Duct Parameters

Feature

High Efficiency: The inner wall adopts hydrodynamically optimized smooth polishing process with extremely low airflow resistance, effectively reducing air volume loss and turbulence noise during transmission, ensuring stable air volume at the end of the pipeline and efficient long-distance air delivery. Automatic Restart Function: As a pure physical ventilation pipe fitting, it requires no independent control system. It is fully compatible with the operation logic of various air coolers and ventilation equipment, and maintains stable air delivery performance synchronously with the host unit without additional debugging. Standardized Connection Design: Adopts national standard socket connection size with built-in high-elastic sealing ring, which achieves reliable airtight performance after direct plug-in, avoiding air leakage and ensuring stable ventilation efficiency. Modular Design: Standardized fixed-length straight pipe production, which can be freely cut and spliced according to on-site pipeline length requirements. It is matched with elbows, tees and other pipe fittings of the same series, supporting flexible combination of complex pipeline routes. Advanced Material Technology: Adopts weather-resistant modified PP material added with anti-aging and anti-UV agents, with excellent flame retardant, corrosion resistant and anti-aging properties. It effectively avoids rust and corrosion problems of traditional metal air ducts, and achieves ultra-long service life.

Advantages

High Airflow Efficiency: The ultra-smooth inner wall greatly reduces airflow resistance and frictional loss, ensuring unobstructed air transmission with minimal air volume attenuation. It supports large-air-volume long-distance delivery, with uniform wind speed and high ventilation efficiency. Energy Efficiency: Low wind resistance design reduces the extra load and power consumption of the air cooler fan, effectively lowering the overall operating energy consumption of the ventilation system, and saving long-term operation costs. Ultra-Long Durable Design: Weather-resistant modified PP material with anti-aging formula, no rust, no corrosion, no embrittlement. Its service life reaches more than 12 years, which is 2–3 times that of traditional galvanized iron ducts and 40% longer than ordinary PP ducts, greatly reducing the frequency of pipeline replacement. Rapid Installation: Lightweight pipe body with standardized socket connection, no welding or flange fixing required. It can be cut and spliced on site quickly, with installation efficiency more than 50% higher than traditional metal air ducts, greatly shortening the project construction period. Low Maintenance Requirements: Smooth inner wall is not easy to accumulate dust and scale, and daily maintenance only requires simple regular cleaning. The pipe body has stable performance with no wearing parts, no anti-rust treatment or regular anti-corrosion maintenance is needed, and the long-term use cost is extremely low. Versatile Compatibility: Standard caliber design is fully compatible with elbows, tees, reducers and other pipe fittings of the same series. It is widely used in industrial cooling, agricultural ventilation, commercial fresh air, industrial exhaust and other scenarios, and matches all kinds of mainstream industrial air coolers and ventilation equipment.
