Ventilation flat horizontal duct tee AWENTA KP75-26, rectangular 75×150 mm

Flat horizontal ventilation tee AWENTA KP75-26 for rectangular ducts with cross-section 75×150 mm. Designed to branch airflow in ventilation and air-exhaust systems, this flat horizontal tee connects rectangular ducts and enables a smooth change of flow direction while keeping a low installation profile. The component is intended for use in situations where space-saving flat ductwork is required and where reliable airflow distribution is needed in residential and commercial ventilation installations.

Advantages

The flat horizontal tee provides a compact connection that preserves airflow efficiency and reduces turbulence at the branch point. Its rectangular, low-height design allows installation in shallow or confined ceiling and wall cavities. The tee is compatible with standard flat duct dimensions and simplifies routing of ventilation and exhaust air without the need for large circular fittings. Constructed for typical ventilation environments, it supports straightforward integration into existing flat duct systems.

Suitable for

• Domestic ventilation and extractor fan ducting in limited-height cavities
• Commercial and office HVAC systems where flat ducts are used
• Renovation projects requiring space-saving branch connections
• Air distribution and exhaust systems with rectangular 75×150 mm ducts

Key specifications

• Rectangular cross-section compatibility: 75 × 150 mm
• Configuration: flat horizontal tee for branching airflow
• Application: ventilation and air-exhaust systems
• Installation orientation: horizontal branch
• Form factor: low-height rectangular fitting for space-constrained installations

How to use

Position the flat horizontal tee at the required branch location within the rectangular duct run and ensure the mating duct ends are clean and free from obstructions. Slide or insert the duct ends into the tee openings and secure connections according to local ventilation practice, using appropriate sealants, tape, or mechanical fasteners to maintain airtight joints. Check alignment to avoid kinks or sharp bends in connected ducts and verify that the branch direction is correct for the intended airflow. After installation, test airflow and inspect for leaks.

Usage recommendations

For best performance, use this tee with rectangular ducts sized 75×150 mm and maintain smooth internal transitions. Seal joints properly to minimise air leakage and noise. Where necessary, provide access panels or removable sections for inspection and cleaning of branch lines.
