Polypropylene (PP) Air Conditioning and Ventilation Ducts
Polypropylene (PP) air conditioning and ventilation ducts are designed for industrial HVAC systems operating in demanding environments where vapors, gases, and corrosive chemical substances are present. The ducts are manufactured from high-quality thermoplastic materials with excellent chemical resistance, providing a reliable, safe, and long-term solution for conveying clean or contaminated air in industrial facilities.
Thanks to the combination of resistance to acids and alkalis, low weight, and full engineering flexibility, polymer duct systems offer an advanced alternative to metal ducts in environments requiring high resistance to corrosion and humidity.
Key Advantages
-
Exceptional chemical resistance to acids, alkalis, and aggressive gases
-
Ideal solution for industrial air conditioning and ventilation systems
-
Lightweight construction for easy installation and suspension
-
Smooth internal surfaces for efficient airflow and reduced contaminant buildup
-
No rust, no corrosion, and no need for protective coatings
-
Long service life, even under harsh operating conditions
Range of Materials According to Project Requirements
In addition to polypropylene (PP), air conditioning and ventilation ducts can also be manufactured from other thermoplastic materials, depending on the process conditions, temperature, and conveyed media:
-
PP-R / PPR – Suitable for higher temperature systems and advanced industrial applications
-
PP-H (PPH) – Higher rigidity and improved pressure resistance
-
HDPE – Excellent resistance to mechanical impact and outdoor environments
-
Other polymeric materials – According to specific chemical and engineering requirements
Material selection is performed following a full engineering evaluation of the operating conditions.
