## Summary description

Ventilation clamp with lining 100 BK by Niczuk, model 81210210000. A metal pipe/clamp accessory designed for securing Ø100 mm ventilation ducts with an external protective or decorative lining (BK). Suitable for fixing round ventilation pipes, exhaust ducts and HVAC installations in residential and commercial buildings. Provides stable mechanical support and helps reduce air leakage and vibration.

## Long description

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.
