Ventilation Clamp Walraven Aero EPDM M8 Ø140 mm, model 4115140

Walraven Aero EPDM ventilation clamp for Ø140 mm round ducts provides a secure, vibration-damped support for HVAC and ventilation installations. The clamp is designed to accommodate an M8 threaded rod for suspension and fixation. A resilient EPDM lining protects duct surfaces, reduces transmission of vibration and helps maintain an airtight connection around the duct circumference. The component is suitable for use in residential and commercial buildings where reliable duct suspension and sealing are required.

Advantages

The EPDM lining delivers both mechanical protection and sound-dampening properties, while the robust metal clamp body ensures stable load-bearing performance. Compatibility with standard M8 threaded suspension systems simplifies installation and integration with existing mounting hardware. The design minimizes risks of duct deformation and mitigates noise transfer from mechanical equipment to the structure.

Suitable for

• Suspension and support of round ventilation ducts with 140 mm outer diameter
• HVAC installations in residential, commercial and light-industrial buildings
• Areas requiring vibration isolation and airtight sealing of duct connections
• Integration with threaded rod M8 suspension systems and pipework supports

Key specifications

• Designed for round ducts with outer diameter: 140 mm
• Lining material: EPDM rubber for vibration damping and sealing
• Mounting interface: accepts M8 threaded rod for suspension
• Construction: metal clamp body with elastomer insert for protection

How to use

Position the clamp around the duct so the EPDM lining contacts the duct surface evenly. Close and secure the clamp body according to the manufacturer's fastening method, ensuring the duct is centered and not pinched. Suspend the clamp from an M8 threaded rod, adjusting the rod length and securing nuts to achieve the required elevation and alignment. Verify the clamp provides continuous contact with the duct and that the EPDM lining forms a tight seal without compressing the duct material beyond recommended limits.

Usage recommendations

Inspect the EPDM lining for damage before installation and replace the clamp if the lining is degraded. Avoid overtightening the clamp to prevent deformation of lightweight ducts. For installations exposed to aggressive chemicals or direct sunlight, confirm EPDM compatibility with the specific environment. Follow local building codes and ventilation standards for spacing and load requirements.
