SpiroFlex 200/160 mufowo-nyplowa redukcja – 200 mm na 160 mm mufowo-nyplowa

SpiroFlex 200/160 mufowo-nyplowa redukcja – 200 mm na 160 mm mufowo-nyplowa is a circular duct transition component designed to connect 200 mm diameter ventilation pipes to 160 mm diameter pipes. The reduction uses a socket-and-spigot (mufowo-nyplowa) joint to enable straightforward assembly and a secure fit that supports airtight connections in HVAC systems. It is intended for use in ventilation, extraction and air distribution systems in residential and commercial environments where a reliable diameter transition is required.

Advantages

The mufowo-nyplowa joint simplifies installation by allowing quick, tool-light assembly and reduces the need for additional sealing components. The reduction is compatible with standard circular ventilation ductwork dimensions, enabling smooth airflow transition with minimal turbulence when properly installed. Its construction ensures a stable mechanical connection and helps maintain system tightness, which supports energy-efficient ventilation operation.

Suitable for

• Connecting 200 mm circular ducts to 160 mm circular ducts in ventilation systems
• Air extraction and supply installations in apartments and houses
• Commercial HVAC systems requiring duct diameter reduction
• Maintenance or retrofit projects where existing duct sizes must be joined

Key specifications

• Input diameter: 200 mm (circular duct)
• Output diameter: 160 mm (circular duct)
• Joint type: socket-and-spigot (mufowo-nyplowa)
• Application: ventilation, extraction and air distribution systems
• Compatibility: standard circular sheet metal/spiral ducts with matching diameters

How to use

Position the larger end of the reduction onto the 200 mm duct and insert the smaller end into or over the 160 mm duct according to the duct system arrangement and the mufowo-nyplowa joint orientation. Ensure that both duct ends are clean and free of deformation before assembly. Push the socket and spigot fully together until the joint seats, then check for alignment and straightness of the connected ducts. Where required by local practice or building codes, apply an appropriate gasket or silicone sealant at the joint and secure connections with clamps or sheet metal screws placed to avoid disturbing the seal.

Usage recommendations

For best performance, use the reduction within ventilation systems designed for the corresponding airflow rates; avoid using the fitting in locations with extreme vibration or chemical exposure unless materials are specified for such conditions. After installation, verify system airtightness and airflow balance; perform periodic inspections to confirm the joint integrity and re-tighten mechanical fasteners if necessary.
