Flat ventilation duct AWENTA KP75-05 75×150 mm, length 0.5 m

Flat ventilation duct AWENTA KP75-05 75×150 mm, length 0.5 m is a rectangular-section duct element intended for air distribution and exhaust systems. The compact 75×150 mm cross-section and short 0.5 m length make this section suitable for routing ventilation in areas with restricted vertical or horizontal space. It is designed to connect with compatible rectangular ducts and fittings in residential and light-commercial HVAC installations, providing a standardized segment for building duct runs.

Advantages

This flat ventilation duct offers a low-profile rectangular shape that simplifies installation in tight cavities and above suspended ceilings. Its standardized dimensions ensure compatibility with common rectangular fittings and connectors, facilitating modular assembly and repair. The short length reduces the need for on-site cutting when routing through constrained zones and helps maintain consistent airflow properties across the network.

Suitable for

• Routing ventilation ducts in spaces with limited clearance such as under beams, in crawlspaces, or above suspended ceilings
• Connecting rectangular duct runs in residential HVAC systems
• Small commercial and retail ventilation installations requiring compact ductwork
• Retrofit projects where replacing round ducts with low-profile rectangular sections improves fit

Key specifications

• Cross-section: 75 × 150 mm (rectangular)
• Length: 0.5 m
• Shape: Flat / rectangular profile suitable for low-height installations
• Application: Air distribution and exhaust systems for ventilation
• Compatibility: Designed to be joined with rectangular duct fittings and connectors of matching dimensions

How to use

Select the flat duct section according to the required cross-section and route it through the installation path, aligning ends with adjacent duct segments or fittings. Use appropriate rectangular connectors, seals, and fasteners to secure joints and preserve airtightness. Support the duct at regular intervals with hangers or brackets to prevent sagging and to maintain gradient where necessary. After assembly, perform a visual inspection and, if required, a leak test to confirm correct installation and airflow continuity.

Usage recommendations

When installing this flat ventilation duct, ensure compatibility with existing rectangular components and use suitable sealing materials at joints to minimize air leakage. Avoid sharp bends that could restrict airflow and maintain recommended support spacing for the duct profile. In environments with higher humidity or corrosive conditions, select corrosion-resistant mounting hardware and inspect connections periodically.
