Ventilation Duct Elbow 15 Degrees PVC-U d50-1250 mm

  Datasheet (PDF)

The HoKa 15 degrees PVC-U ventilation duct elbow is an injection-moulded thermoplastic fitting engineered for directional changes in industrial exhaust air and aggressive chemical fume extraction systems. Designed specifically for ventilation contractors and industrial plant engineers, this circular duct component ensures continuous airflow efficiency and reliable containment across diameters from 50 mm up to 1250 mm.

Technical specifications

This circular ventilation elbow provides an exact 15 degrees angle of deflection while preserving optimal aerodynamic velocity and minimal pressure loss. Its design integrates a curvature radius equal to the diameter (R = D) to prevent turbulent resistance along exhaust routes.

• Angle of deflection: 15 degrees for circular ventilation ducts
• Curvature geometry: Constant centerline radius R = D
• Socket design: Integral female sockets based on DIN 8062 dimensions
• Material formulation: High-grade unplasticized polyvinyl chloride (PVC-U)
• Color: Standard industrial dark grey (RAL 7011)
• Nominal diameter range: Continuous sizing from d50 mm up to d1250 mm

Applications

The component is engineered for air extraction lines exposed to aggressive chemical vapors, humid air, and corrosive exhaust gases. It operates reliably under industrial ventilation pressures in environments where metallic ducting suffers rapid chemical degradation.

Key deployment areas include chemical processing plants, electroplating and surface finishing facilities, industrial scrubber networks, pharmaceutical production zones, and municipal wastewater treatment odor-control lines. It is fully compatible with standard plastic ventilation piping networks handling acid fumes and alkaline vapors.

Installation and jointing

Installation is executed by jointing the integral female sockets directly onto plastic ventilation pipes, utilizing either solvent cementing or plastic hot-gas welding techniques. Calibrated internal stops ensure true axial alignment and correct insertion depth during assembly.

Prior to permanent bonding, the duct spigots and fitting sockets must be thoroughly cleaned and prepared using matching PVC cleaners. Assemblies solvent-welded or hot-gas welded according to professional standards form gastight and pressure-resistant duct joints that eliminate the need for fabricated segmented elbows.
