## Summary description

SpiroFlex 140 smooth stainless steel duct pipe (model SX-WN140SG) is a 1 meter length ventilation component designed for air distribution and exhaust systems. The smooth stainless surface reduces airflow resistance and facilitates cleaning. Suitable for HVAC installations, ventilation joins, and retrofit projects requiring corrosion-resistant, rigid ducting in residential and commercial applications.

## Long description

SpiroFlex 140 smooth stainless steel duct pipe, model SX-WN140SG, is a 1 m length ventilation component engineered for air distribution and exhaust systems. The pipe features a smooth internal surface made of stainless steel to reduce airflow resistance and simplify maintenance. Its rigid construction provides stable duct runs for residential and commercial HVAC installations, retrofit projects and locations where corrosion resistance and ease of cleaning are required.
Advantages
The smooth stainless steel interior lowers friction loss and supports consistent airflow, improving overall ventilation performance. Rigid construction maintains shape under pressure and prevents sagging and vibration common with flexible alternatives. The stainless material resists corrosion, is easy to wipe clean, and tolerates typical duct cleaning methods. Standardized 1 m length allows predictable layout planning and straightforward joining with compatible fittings.
Suitable for
Residential HVAC supply and exhaust ducts
Commercial ventilation runs in shops, offices and light industrial spaces
Retrofit and renovation projects requiring rigid, corrosion-resistant ducting
Areas where frequent cleaning or hygiene control is needed
Key specifications
Material: stainless steel with smooth internal finish
Nominal diameter: 140 mm
Length: 1 metre
Form: straight, rigid duct pipe
Surface: smooth interior to reduce airflow resistance and facilitate cleaning
How to use
Install the SpiroFlex 140 duct pipe as part of a continuous duct run, aligning ends with compatible fittings or connectors and securing joints with clamps, silicone sealant or approved duct tape to ensure airtight connections. Support the pipe at regular intervals using appropriate hangers or brackets to prevent deflection. When integrating with other ventilation components, verify that flow direction, slope for condensate drainage (if applicable) and clearance for maintenance are observed. Follow local ventilation codes and manufacturer instructions for jointing and fastening to ensure system performance.
Usage recommendations
For optimal airflow and longevity, avoid sharp bends directly adjacent to the pipe ends; use gradual transitions and compatible couplings. Clean the interior surface with non-abrasive detergents and soft cloths or brushes to maintain smoothness and hygienic conditions. Inspect support points and seals periodically and replace damaged seals to preserve airtightness and corrosion resistance.
