The combustion air intake hose is specially designed for air heaters, providing a reliable and flexible solution for fresh air supply to combustion systems. This hose delivers stable airflow to support efficient combustion while protecting air heater equipment from heat, vibration, and installation stress.
The hose is manufactured using a multi-layer composite structure, typically composed of glass fiber, aluminum foil, kraft paper, and PVC, forming a corrugated tube design. This structure offers excellent flexibility, heat resistance, and mechanical strength, making it ideal for air heater combustion air intake applications.

Designed specifically for air heater combustion air intake
Corrugated tube structure for superior flexibility
Lightweight yet durable composite construction
Good heat resistance and insulation performance
Easy installation in compact or irregular spaces
Cost-effective solution for combustion air systems
The combustion air intake hose is constructed using carefully selected composite materials:
Glass fiber – provides heat resistance and structural strength
Aluminum foil – reflects heat and improves thermal insulation
Kraft paper – enhances shape stability and cost efficiency
PVC layer – improves abrasion resistance and durability
The corrugated tube structure allows the hose to bend easily without collapsing, ensuring consistent airflow even in tight installation environments.
