For optimal performance, just remember to check the airflow of your system; in some cases, a slightly larger diameter may be recommended to limit pressure losses.
- Is the 10m Kombi-Alu/PVC duct with a diameter of 200mm suitable for tight bends in a small space?
The Kombi-Alu/PVC duct of 10 m with a diameter of 200 mm is semi-rigid and offers good robustness, but its flexibility is limited. For tight bends in a confined space, this large diameter makes bending difficult, with a risk of reducing the air passage or damaging the duct.
It is therefore preferable to provide a sufficiently wide bend radius or to opt for a smaller diameter if the installation requires very pronounced curves. For tight spaces, specific bends suitable for the 200 mm diameter can also be considered to facilitate installation without compromising air flow.

The Combi Duct in Aluminum/PVC 200 mm - 10 m has excellent flexibility, ideal for complex tunneling under LED lighting. Its flexible structure allows for efficient management of direction changes without causing significant losses in efficiency or airflow.
To ensure optimal performance, simply avoid folds or tight bends and keep the duct well stretched. With a properly sized extraction system, this duct ensures excellent sealing and efficient airflow, even in technical configurations.
- Is the Combi alu PVC 200mm duct suitable for extraction in humid environments, and what are its performance parameters in terms of tightness and flexibility?
The Combi Alu/PVC 200 mm duct over 10 m is perfectly suited for extraction in humid environments thanks to its lining that ensures good tightness, limiting odor leaks and risks related to condensation. To maintain this tightness, it is important to securely fix the duct with clamps or aluminum tape.
It also offers great flexibility, capable of fitting into tight spaces and supporting bends without kinking or causing a significant loss of flow, greatly facilitating installation in constrained environments.
In summary, this duct is robust and suitable for humid conditions, provided that the installation is well-managed and the sizing of the extraction system is checked to ensure its effectiveness.
- What is the flexibility of this aluminum/PVC duct 200mm for installation on a ventilation system with bends?
The Kombi-Alu/PVC-Mantel 10 m – 200 mm duct is designed to provide good flexibility, ideal for installations in ventilation systems requiring bends. Its structure, combining an inner aluminum layer and an outer PVC layer, ensures both mechanical strength and adaptability to curves.
It can therefore be bent to fit the configuration of your ventilation network while maintaining good performance. For optimal use, it is recommended to handle the duct without excessively forcing the bends in order to preserve its integrity and lifespan.
- Is it possible to connect a 200mm aluminum/PVC duct to a 180mm extractor without significant loss of efficiency?It is perfectly possible to connect a 200 mm diameter aluminum/PVC duct to a 180 mm extractor using an appropriate reducer. The difference in diameter results in a reduction of the cross-sectional area by about 19%, which may slightly increase the air speed, but if the junction is made properly with a quality adapter, this loss of efficiency remains very low and negligible in most domestic installations.
Ensure to use a well-fitted reducer 200 mm → 180 mm to ensure airtightness and avoid turbulence, which will guarantee optimal performance of your ventilation system.
- Can this 200mm alu PVC duct be easily connected to standard extractors and filters in an indoor growing installation without specific adapters?
The Combi Alu/PVC 10m - 200mm duct is perfectly compatible with standard 200mm extractors and filters, a very common size in indoor growing. No specific adapter is needed for the connection. It is simply important to securely attach the duct with clamps or aluminum tape to ensure airtightness and prevent leaks.
However, its semi-rigid nature somewhat limits flexibility, so it's essential to avoid sharp bends that could damage the duct or restrict airflow. With these precautions, the installation remains straightforward and efficient.
- What is the friction loss coefficient per linear meter for this aluminum/PVC duct of 200mm?
For the Kombi-Alu/PVC-Mantel 10 m – 200 mm, the friction loss coefficient per linear meter is generally estimated at around 10 Pa/meter. This value is based on a hydraulic roughness coefficient equivalent to that of new PVC (C ≈ 150), due to the smoother aluminum inner surface combined with the PVC.
This estimation may vary slightly depending on the air flow, but it serves as a reliable basis for your ventilation calculations. If you would like a calculation tailored to a specific flow rate, please let us know this parameter for more precise advice.
- What is the maximum thermal resistance of this 200mm alu pvc combi duct when used with a powerful LED extractor in SCROG?The 200 mm Combi duct made of Alu/PVC is designed to withstand high temperatures thanks to its double aluminum-PVC layer, making it ideal for use with a powerful LED extractor in SCROG.

- What is the maximum air flow capacity for this 200mm aluminum/PVC duct over 10m without significant pressure loss?
For the 200 mm diameter Kombi-Alu/PVC duct over 10 m, the maximum air flow capacity without significant pressure loss is around 650 to 700 m³/h. This estimate is based on an average air speed of about 6 m/s, which helps limit pressure drops and noise while ensuring good air passage due to its cross-section of 0.0314 m².
Its semi-rigid design with an internal aluminum layer and external PVC provides a degree of flexibility and robustness, ideal for installations requiring adjustments without reducing the flow. However, it is important to avoid overly tight bends or deformations on the duct, as these would increase pressure loss.
- Does the 10m Alu PVC sheath withstand prolonged outdoor use without degradation or loss of waterproofing?
The Combi Alu/PVC 10m - 200mm diameter sheath is designed to provide good mechanical and thermal resistance due to its structure combining aluminum and PVC. It ensures effective sealing against light and odor leaks when installed correctly, with appropriate fixings for the connections.
For prolonged outdoor use, it can hold up without degradation or loss of waterproofing, provided it is carefully installed, avoiding tight bends and protecting the sheath from climatic aggressions (UV, rain, temperature variations). However, it is not specifically formulated to withstand severe weather conditions for very long periods, so it is advisable to regularly check its condition under these circumstances.
- Is the Combi alu/PVC duct 200mm compatible with standard domestic ventilation systems for home automation integration?
The Combi Alu/PVC 10m - 200mm diameter duct is perfectly compatible with standard domestic ventilation systems, such as VMCs, extractors, and classic ventilators. Its semi-rigid design in aluminum and PVC ensures good thermal resistance and effective sealing against air and odor leaks, which is ideal for reliable integration into a home automation system.
It fits equipment with a diameter of 200 mm, a common format, and its flexibility allows for easy installation even in confined spaces.
