## Summary description

Niczuk ventilation clamp with lining, size 630, designed to secure round duct connections in ventilation and air-conditioning systems.

## Long description

Niczuk ventilation clamp with lining size 630 is designed to fasten round duct connections in ventilation and air-conditioning systems. The lined band provides a secure mechanical joint while protecting duct edges and improving the seal between mating pipes. The clamp reduces vibration transfer at connections and helps maintain airtightness in industrial and commercial HVAC installations where a lined fastening is required.
Advantages
The lining inside the clamp cushions the joint surface, preventing damage to duct edges and reducing noise and vibration transmission. The round band design ensures even pressure around the connection for consistent sealing. Constructed for HVAC use, the clamp is suitable for repeated assembly and disassembly without degrading the mating surfaces when installed correctly.
Suitable for
 Securing round metal ducts in ventilation systems
 Air-conditioning duct connections in commercial buildings
 Industrial HVAC installations requiring lined fastenings
 Applications where vibration damping and improved airtightness are needed
Key specifications
 Type: Lined round duct clamp
 Nominal size: 630 mm diameter
 Function: Mechanical fastening and sealing of duct joints
 Material characteristics: Metal band with internal lining for protection and damping
 Application environment: Ventilation and air-conditioning systems, industrial and commercial use
How to use
Position the lined clamp over the meeting edges of the two round duct sections so the lining contacts the duct surfaces. Tighten the band evenly around the circumference until the desired compression of the lining is achieved and the connection is secure; ensure not to overtighten to avoid deforming the ducts. Check the joint for even contact and airtightness after installation and re-tighten if necessary following the manufacturer's torque or tightening guidance for similar band clamps.
Usage recommendations
For best performance, inspect mating duct edges before assembly and remove sharp burrs. Use the clamp in environments compatible with the lining material and avoid over-tightening. Periodically inspect installed clamps for loosening, corrosion, or lining wear, especially in industrial environments with vibration or corrosive agents.
