SpiroFlex stainless adjustable elbow SpiroFlex 150 (model SX-WN150KN)

SpiroFlex stainless adjustable elbow SpiroFlex 150 (model SX-WN150KN) is a corrosion-resistant pipe fitting designed to change direction in ventilation and ducting systems with a nominal 150 size. The product features an adjustable joint that enables installers to correct alignment and set the required angle on site, reducing the need for precise pre-fabrication. Constructed from stainless steel, the elbow provides enhanced durability and resistance to moisture and common corrosive agents found in HVAC and industrial environments.

Advantages

The adjustable stainless steel elbow offers reliable corrosion resistance and mechanical strength suitable for long-term use. Its adjustable joint simplifies installation by allowing fine angle and alignment corrections without additional cutting or welding. The smooth internal surface supports efficient airflow and helps to limit pressure losses and particulate accumulation. The product's robust construction makes it compatible with common duct connection methods and sealing materials used in ventilation systems.

Suitable for

• HVAC ventilation branches and directional changes in air distribution systems
• Industrial exhaust ducts where corrosion resistance is required
• Retrofit projects where on-site angle adjustment is needed
• Commercial and light industrial installations using 150 nominal size ducting

Key specifications

• Material: stainless steel for corrosion resistance and durability
• Type: adjustable elbow with articulated joint for angle correction
• Nominal size: 150 (suitable for ducts and fittings of 150 nominal diameter)
• Internal finish: smooth to support efficient airflow
• Application: ventilation, air distribution, and industrial exhaust systems

How to use

Position the adjustable elbow at the required change of direction and set the joint to the desired angle by loosening the adjustable mechanism, aligning the two duct ends, and then tightening the connection according to manufacturer guidance or site practice. Ensure mating duct ends are clean and free of debris before assembly. Use appropriate sealing (gaskets, sealant, or tape) and fastening methods compatible with stainless steel to secure the joint and prevent air leakage. Confirm alignment and secure all fasteners before commissioning the system.

Usage recommendations

Inspect the elbow before installation for surface damage or deformation. For systems handling corrosive gases or high humidity, verify compatibility of the specific stainless steel grade with the environment and consider additional protective measures if needed. Follow local ventilation codes and best practices for sealing and support to maintain airflow performance and system integrity.
