ventilation clamp with lining 100 BK Niczuk 81210210000

Ventilation clamp with lining 100 BK by Niczuk is a metal mounting accessory designed to secure round ventilation ducts with a 100 mm outer diameter that include an external protective or decorative lining (BK). It provides a stable mechanical connection between the duct and supporting structures, suitable for use in residential and commercial HVAC systems. The design reduces vibration transfer and helps maintain duct alignment while limiting air leakage at the fixing point.

Advantages

The clamp combines a robust metal band with an integrated lining that protects the duct surface from abrasion and prevents damage to the outer finish. Its geometry ensures even pressure distribution around the duct circumference, delivering stable support and minimizing deformation of thin-walled pipes. The lined surface reduces direct metal-to-metal contact, decreasing vibration transmission and helping preserve acoustic performance of the ventilation system.

Suitable for

• Securing Ø100 mm round ventilation and exhaust ducts in HVAC installations
• Mounting ducts where an external protective or decorative lining (BK) is present
• Applications requiring reduced vibration transfer and minimized air leakage at attachment points
• Residential and commercial ventilation systems, including kitchen and bathroom exhausts

Key specifications

• Material: metal clamp with integrated protective lining
• Intended duct outer diameter: 100 mm
• Function: mechanical support and fixation of round ventilation ducts
• Effect: reduces vibration transmission and helps limit air leakage at the mounting point
• Suitable environment: indoor HVAC installations in residential and commercial buildings

How to use

Position the lined clamp around the Ø100 mm duct so the lining contacts the duct surface evenly. Align the clamp with the supporting structure, then tighten the fastening mechanism until the clamp secures the duct without compressing or deforming it. Ensure the clamp is placed at recommended intervals along the duct run to provide adequate support and prevent sagging. Check that the lining remains intact and that the clamp does not create sharp pressure points on the duct outer surface.

Usage recommendations

Use these clamps in combination with appropriate suspension or support hardware rated for the load and environment. Avoid overtightening to prevent damage to lined or thin-walled ducts. Inspect clamps periodically for corrosion or lining wear, and replace if protection is compromised.
