APK is pleased to announce the availability of its flexible combustion air intake tube solutions, designed to meet the growing demand for reliable and adaptable combustion air supply components in industrial applications.

The combustion air intake tube, also commonly referred to as a combustion air supply pipe, plays a critical role in delivering stable intake air from upstream equipment—such as air intake silencers and filtration systems—to the combustion air inlet of turbines, boilers, and industrial burners.

Multi-Layer Composite Structure for Reliable Performance

The standard APK combustion air intake tube features a three-layer composite construction:

• Outer Layer: Black PVC for mechanical protection and abrasion resistance

• Middle Layer: Kraft paper to enhance structural stability and shape retention

• Inner Layer: Aluminum foil providing a smooth airflow surface and moisture resistance

This combination offers an effective balance between flexibility, durability, and airflow efficiency, making the product suitable for various industrial combustion air intake systems.

Multiple Names, One Functional Solution

Depending on industry practices and application requirements, this product may be identified by different names, including:

• Combustion Air Intake Tube

• Combustion Air Supply Pipe

• Combustion Air Intake Hose

• Combustion Air Flexible Duct

Although the terminology may vary, all refer to the same functional component within a combustion air intake system.

Custom Material Options Available

In addition to the standard PVC, kraft paper, and aluminum foil structure, APK offers custom material and structural options to suit specific operating conditions. Alternative designs can be developed to accommodate higher temperatures, humidity levels, or special installation requirements.

Custom diameters, lengths, and connection methods are also available, allowing seamless integration into both new installations and retrofit projects.

Applications Across Industrial Combustion Systems

APK combustion air intake tubes are widely used in:

• Gas turbine combustion air intake systems

• Industrial boilers and burners

• Power generation and CHP systems

• Industrial engine air supply applications

The flexible design supports easy installation while helping to absorb vibration and alignment tolerances.

Commitment to Engineering and Manufacturing Quality

As a manufacturer of combustion air system components, APK continues to focus on engineering-driven design, material reliability, and consistent manufacturing quality. Each product is developed to support long-term system performance and stable combustion operation.
