Ventilation clamp Walraven Aero EPDM M8 150mm

Walraven Aero EPDM M8 150mm ventilation clamp is designed for secure support and mounting of round ducts and ventilation pipes in HVAC systems. The clamp features an internal EPDM lining that provides vibration damping and contributes to an airtight fit around ducts with a nominal 150 mm diameter. With an M8 fastening thread, the clamp integrates into threaded rod and support systems commonly used in commercial and residential installations.

Advantages

The EPDM lining reduces noise transmission and protects ducts from surface damage while improving sealing properties. Its metal construction provides reliable mechanical strength for duct suspension and anchoring. The M8 threaded connection enables straightforward attachment to standard threaded rods, minimizing installation time. The clamp's 150 mm clamping range matches common ventilation pipe sizes, simplifying component selection for HVAC projects.

Suitable for

• Mounting and suspending round ventilation ducts with approx. 150 mm diameter
• HVAC installations in commercial and residential buildings
• Duct support clamps in mechanical rooms and ceiling voids
• Applications requiring vibration damping and improved airtightness

Key specifications

• Clamp type: single-piece circular clamp with internal lining
• Internal lining material: EPDM for damping and sealing
• Fastening thread: M8 compatible with threaded rods and bolts
• Clamping diameter: designed for 150 mm round ducts
• Material: corrosion-resistant metal construction suitable for HVAC environments

How to use

Position the clamp around the round duct so the EPDM lining contacts the duct surface evenly. Tighten the fastening bolt or nut on the M8 thread to secure the clamp to a threaded rod, bracket or support profile. Adjust the clamp position along the support system to achieve correct duct alignment and slope, then retighten to the required torque recommended for the installation. Ensure the EPDM lining remains intact and provides continuous contact for vibration isolation and sealing.

Usage recommendations

Inspect the EPDM lining before installation and replace the clamp if the lining is damaged. Use corrosion-appropriate fasteners and follow local codes for spacing of duct supports. For optimal performance, avoid overtightening which may deform the duct or compress the EPDM excessively; tighten to a level that secures the duct without damaging the lining.
