Aluminum Flexible Duct Prodmax FLEX 115mm 1m (model RF 115)

Aluminum Flexible Duct Prodmax FLEX 115mm 1m (model RF 115) is a lightweight, bendable ventilation duct with a nominal internal diameter of 115 mm and a length of 1 meter. It is made from corrugated aluminum material designed for air distribution, extractor fan connections and general ventilation tasks in residential and light-commercial installations. The flexible construction enables routing through restricted spaces and alignment with matching 115 mm fittings for a secure mechanical connection.

Advantages

The flexible aluminum construction combines low weight with sufficient form stability for temporary bends and moderate routing. Corrugated walls provide flexibility while maintaining an open air passage; the material resists corrosion and is suitable for standard ventilation air flows. The 115 mm diameter matches common extractor fan outlets and duct connectors, simplifying installation and reducing the need for adapters. Its 1 meter length offers a balance between reach and compact handling during installation.

Suitable for

• Connecting domestic extractor fans to exhaust vents
• Routing ventilation air in bathrooms, kitchens and utility rooms
• Temporary or semi-permanent ducting in light-commercial spaces
• Situations requiring flexible routing through studs, joists or cabinetry

Key specifications

• Material: corrugated aluminum
• Internal diameter: 115 mm (nominal)
• Length: 1 meter
• Construction: flexible, corrugated tube
• Application: ventilation and extractor fan connections

How to use

Measure the required routing length and confirm that both the fan outlet and the receiving duct or grille accept a 115 mm diameter connection. Trim the duct to the needed length using tin snips or a suitable cutter, taking care to deburr cut edges. Slide the duct over the mating collar or spigot and secure with a clamp, foil tape or hose clip to ensure a mechanical seal. Avoid sharp kinks and compressions that would restrict airflow; support long runs to prevent sagging.

Usage recommendations

For reliable performance, ensure the duct run is as straight and short as practicable, with gentle bends rather than tight folds. Use corrosion-resistant clamps or aluminum foil tape to maintain an airtight joint. Do not use this duct for conveying combustible gases, high-temperature exhausts, or corrosive chemical vapors. Inspect connections periodically and replace the duct if visible damage or severe deformation is present.
