Ricom elbow PP-AL 45° DN60/100 for ventilation ducts

Ricom elbow PP-AL 45° DN60/100 for ventilation ducts is a circular ventilation fitting designed to change the airflow direction by 45 degrees in systems using DN60/100 ducting. Manufactured from polypropylene with an embedded aluminum layer (PP-AL), the elbow combines chemical resistance and low weight of plastic with increased stiffness provided by the metal layer. The product is intended for residential and light commercial air distribution and exhaust installations where compact, corrosion-resistant fittings are required.

Advantages

The PP-AL construction provides improved rigidity compared with plain polypropylene fittings, reducing deformation under tension and during installation. Its polypropylene surface is resistant to common household chemicals and condensate, while the aluminum layer enhances mechanical durability and dimensional stability. The 45° angle allows smooth directional change with minimal pressure loss compared to sharper bends, and the circular DN60/100 size ensures compatibility with standard small-diameter ductwork.

Suitable for

• Residential ventilation supply and extract systems
• Kitchen or bathroom exhaust ducts in apartments and houses
• Light commercial ventilation where DN60/100 circular ducts are used
• Retrofit projects requiring compact directional fittings

Key specifications

• Material: polypropylene with aluminium inner/outer layer (PP-AL)
• Angle: 45 degrees
• Compatible duct size: DN60/100 (circular ducting)
• Application: air distribution and exhaust in small-diameter systems
• Surface: smooth polypropylene for easy cleaning and reduced flow resistance

How to use

Install the Ricom PP-AL 45° elbow by connecting it between two DN60/100 duct sections, ensuring a snug fit and proper alignment to maintain airflow direction. Use compatible clamps or adhesive joints recommended for PP-AL materials if a sealed connection is required. Verify that the elbow orientation provides the desired 45° change and check for secure fastening to prevent movement or air leakage during operation.

Usage recommendations

For best performance, inspect mating duct ends for burrs or damage before assembly, and ensure joints are clean and dry. Avoid exposure to continuous temperatures beyond the typical operating range of polypropylene-based fittings and consult system specifications for maximum allowed temperatures. Periodic visual inspection is recommended to confirm the elbow remains securely connected and free from obstructions.
