Ventilation flat duct airRoxy 110 x 55 mm, PVC, length 1000 mm

Flat ventilation duct airRoxy 110 x 55 mm, PVC, length 1000 mm is a rectangular-profile duct section designed for low-profile ventilation routes. Manufactured from rigid PVC, this 1‑metre straight segment provides an internal cross-section of 110 × 55 mm and is intended for use in air distribution and extraction systems where limited installation height requires compact duct geometry. The component is compatible with ventilation fans, vents and grilles that accept flat rectangular spigots and can be combined with additional straight sections, bends and connectors to form continuous runs.

Advantages

The PVC construction ensures corrosion resistance and dimensional stability while remaining lightweight for easier handling during installation. The flat rectangular profile enables routing in narrow cavities and below ceilings with minimal loss of headroom. Smooth internal surfaces support unobstructed airflow and reduce dust accumulation compared with porous materials. The standard 1000 mm length simplifies planning and joining of multiple sections to reach required duct runs.

Suitable for

• Low-height ventilation channels in residential properties
• Connecting domestic or small commercial extractor fans to grilles or vents
• Retrofit installations where ceiling void or floor depth is limited
• Air supply or exhaust runs in bathrooms, kitchens and utility rooms

Key specifications

• Internal cross-section: 110 × 55 mm
• Material: rigid PVC
• Length: 1000 mm
• Profile shape: rectangular / flat
• Surface: smooth internal wall

How to use

Select matching duct components and connectors designed for flat rectangular spigots. Measure and cut to length if a shorter segment is required, deburring any cut edges to avoid airflow turbulence. Join sections using compatible couplers or adhesive suitable for PVC, ensuring airtight connections and correct alignment to prevent airflow restriction. Support the duct at regular intervals with clips or brackets appropriate for lightweight PVC to prevent sagging and maintain slope where condensate drainage is necessary. Inspect connections to fans and grilles to confirm sealing and mechanical stability before commissioning.

Usage recommendations

For optimal performance, avoid sharp bends and abrupt transitions that increase pressure loss; use long-radius elbows where possible and maintain straight runs between fittings. Use a compatible PVC solvent or gasketed couplers recommended by the ventilation system designer to secure joints and preserve airtightness. Regularly inspect accessible runs for dust build-up and clean as part of routine ventilation maintenance.
