Ventilation Ducts & Equipment – Solutions for Clean Air

How to choose the right duct diameter

Duct diameter must match the capacity of your fan or extractor – standard diameters are 100mm, 120mm and 150mm. Too small creates resistance and reduces system efficiency, while oversized makes installation difficult. Products like Fleksibilna alum. cev AL Stretch fi 120mm 1.5m Texoflex allow flexible connections where bends are needed along the route.

Aluminum vs plastic ducts

Aluminum ducts withstand high temperatures (up to 250°C) and are ideal for exhausting hot air from kitchens or dryers. Plastic ducts resist moisture better but must not be used near heat sources. Brands like TEXOFLEX and TECHNOFLEX offer ducts with internal steel wire for added stability.

Flexible or rigid ducts

Flexible ducts simplify installation in tight spaces and allow direction changes without additional elbows. Rigid ducts provide a smooth inner surface and better airflow, but require precise route planning. For complex installations, combine both types – rigid ducts for main runs, flexible for final connections.

Additional equipment for complete installation

Besides ducts, you'll need check valves to prevent backflow, condensate traps for humid areas, and transition adapters for different diameters. Brands like AIROXY, AWENTA and DOSPEL offer complete sets of connectors, brackets and sealing tapes. GTV provides aesthetic solutions – ventilation grilles that blend into any interior.

Maintaining your ventilation system

Aluminum ducts should be cleaned at least once a year due to grease and dust buildup – clogged ducts can increase energy consumption by up to 30%. Check joint seals periodically, as air leaks reduce efficiency. Don't overstretch flexible ducts during installation as this increases resistance and system noise.
