Clamp band AWENTA OP7 for ducting Ø150–170 mm

AWENTA OP7 clamp band is a metal fastening band engineered to secure circular ducts and ventilation components with diameters from 150 to 170 mm. Designed for use in HVAC systems, this clamp band creates a reliable mechanical joint between round ducts, vents and fittings, providing stable connection and resistance to axial movement. The simple, robust design allows quick installation and dependable performance in ventilation, extraction and air distribution lines.

Advantages

The clamp band offers a durable metal construction that withstands regular mechanical stress and provides long-term clamping force without deformation. Its adjustable diameter range covers common circular duct sizes, reducing the need for multiple sizes on site. The product enables a tight mechanical connection that helps maintain airflow integrity and limits air leakage at joints.

Suitable for

• Securing round ventilation ducts with diameters 150–170 mm
• Joining ducts to fittings, vents and extraction hoods
• Installation and maintenance of HVAC and exhaust systems
• Temporary or permanent mechanical fastening where a metal clamp is required

Key specifications

• Material: metal fastening band suitable for ventilation applications
• Compatible duct diameter range: 150–170 mm
• Intended connection type: circular ducts, vents and fittings
• Function: provides mechanical clamping to limit axial movement and reduce joint leakage

How to use

Position the clamp band around the overlapping ends of the round duct and fitting so the band sits evenly over the joint. Tighten the fastening mechanism until the band firmly compresses the duct edges to create a secure mechanical connection; avoid overtightening to prevent deformation of thin-gauge duct material. Verify alignment and rotational position of the ducts and ensure the clamp is seated evenly around the circumference for an effective seal and stable joint.

Usage recommendations

Use appropriate hand tools for tightening and check compatibility with the duct material to prevent damage. For applications requiring airtight connections, combine the clamp band with suitable sealing tape or gaskets. Inspect clamped joints periodically as part of routine HVAC maintenance to ensure continued integrity.
