NUOENWEI High-Pressure Rectangular PCA Transition

1. Custom Eccentric Rectangular-to-Rectangular Design

The eccentric transition structure is designed to connect rectangular duct openings with different centerlines, dimensions, or installation positions. Customers can specify the inlet and outlet sizes, transition length, and offset distance according to their equipment layouts.

This non-standard design helps simplify duct connections where conventional straight transitions or rigid fittings are unsuitable.

2. Heavy-Duty Reinforced Fabric Construction

The flexible body is manufactured using industrial-grade coated fabrics, including PVC-coated fabric, polyurethane (PU), and Hypalon. Single-layer and multi-layer reinforced constructions are available to suit different operating environments.

The reinforced fabric structure provides flexibility while offering resistance to mechanical wear and demanding industrial conditions.

3. Designed for High-Pressure Air Transfer

This flexible duct transition is engineered for specified high-pressure air handling applications. Reinforced fabric layers, suitable material selection, and sealed seams help maintain connection integrity during system operation.

Positive-pressure and negative-pressure configurations can be customized according to the actual operating requirements. The final design should be matched to the required static pressure and airflow conditions.

4. Secure Double-Flanged Connections

The double-flanged edge design provides a convenient connection interface between flexible transitions and rectangular ductwork or mechanical equipment.

Drilled and non-drilled flange configurations are available. Flange dimensions, hole positions, and mounting details can be manufactured according to customer drawings.

5. Multiple Material and Safety Options

Different coated fabrics are available to meet specific environmental and safety requirements.

Optional configurations include flame-retardant materials with UL94-V0 or B1-grade specifications, anti-static surfaces, and UV-resistant fabric options.

Material selection can be adjusted based on operating temperature, exposure conditions, and application requirements.

6. Leak-Controlled Manufacturing Process

Depending on the selected material and construction, the transition joint can be manufactured using high-frequency welding or reinforced industrial stitching.

Additional seam sealing tape can be applied to improve joint integrity and reduce air leakage. Manufacturing methods are selected according to the fabric characteristics and project requirements.

7. Vibration Absorption and Installation Flexibility

The flexible fabric body helps absorb equipment vibration and accommodate minor relative movement between connected components.

It also provides installation flexibility where rigid duct connections may transfer excessive mechanical stress to adjacent equipment.

8. Fully Customized OEM and ODM Solutions

NUOENWEI provides non-standard flexible duct transition manufacturing based on customer drawings, samples, or equipment dimensions.

Customization includes:

• Inlet and outlet dimensions

• Rectangular transition geometry

• Eccentric offset direction and distance

Our custom manufacturing service helps customers obtain flexible transition connectors that match their specific equipment and installation requirements.

1. Airport Ground Air Conditioning and PCA Systems

The rectangular PCA flexible transition joint is suitable for airport Preconditioned Air (PCA) equipment and aircraft ground support air conditioning systems.

It can be installed between PCA blower outlets, air delivery ducts, and other rectangular equipment interfaces. Its flexible structure helps accommodate installation misalignment and reduce vibration transmission during air supply operations.

For airport applications, fabric material, temperature resistance, pressure performance, and connection dimensions can be customized according to the PCA equipment specifications.

2. Industrial Blower Inlets and Outlets

Industrial centrifugal blowers and ventilation fans often require flexible connectors between equipment outlets and ductwork.

This rectangular flexible duct transition provides a flexible connection between differently positioned rectangular openings. It helps reduce vibration transfer and accommodates minor installation deviations in industrial air handling systems.

3. Industrial HVAC and Ventilation Systems

In commercial and industrial HVAC installations, duct interfaces may have different dimensions or centerline positions due to equipment layouts and space limitations.

Custom rectangular-to-rectangular flexible transitions provide an adaptable connection solution for ventilation equipment, air handling units, and rectangular duct systems.

4. Dust Collection and Air Extraction Systems

Flexible transitions can be used in selected dust collection and industrial air extraction systems to connect blowers, filtration equipment, and ductwork.

Material selection and construction should be matched to the dust characteristics, operating temperature, pressure, and potential abrasion conditions.

5. Specialized Industrial Air Handling Equipment

Some industrial machines require non-standard air connections that cannot be accommodated by conventional rigid duct fittings.

NUOENWEI custom flexible transitions can be manufactured according to equipment drawings to support specialized ventilation, air delivery, and exhaust applications.

Important: For applications involving high temperatures, abrasive particles, or demanding negative pressure, the material structure and reinforcement should be evaluated against the actual operating conditions.
