FAQ
What material is this ducting made from?+
This ventilation ducting is manufactured from flexible PVC, offering durability and resistance to moisture. This makes it suitable for use in damp environments like bathrooms or kitchens without degrading.
Is the ducting rigid or flexible?+
It's designed to be fully flexible, allowing you to manoeuvre around obstacles during installation and reducing the risk of damage when fitting into tight spaces. The flexibility also helps minimise noise transmission.
What is the maximum operating temperature for this ducting?+
The PVC construction allows for operation up to approximately 60°C. However, we recommend avoiding prolonged exposure to direct sunlight or extreme temperatures to maintain its integrity and prevent deformation.
How should I connect this ducting to an extractor fan?+
You’ll typically use appropriate ducting tape – specifically designed for PVC – to create airtight connections. Ensure the fan outlet matches the 150mm diameter before applying the tape for a secure and efficient fit.
Can I cut this ducting to length?+
Yes, you can easily cut the ducting to your required length using a utility knife or scissors. Just ensure you have suitable protective gloves when handling the material to avoid injury.
What’s the typical application for a 3m length of this size?+
A 3m length is frequently used in kitchens where extending ventilation away from cooking areas and towards external walls is beneficial, or in small workshops needing airflow across a larger space.
Does this ducting require any special fittings?+
While not strictly necessary, additional connectors (elbows, T-pieces) may be useful to navigate corners and direct the airflow precisely. Ensure all fittings are compatible with 150mm diameter ducting.
How do I ensure a tight seal when joining the ducting?+
Applying a generous layer of self-adhesive ducting tape along the seam is crucial for creating an airtight seal. Overlap the tape slightly onto both surfaces to prevent air leakage and maintain optimal airflow performance.
What’s the typical lifespan of this PVC ducting?+
With proper installation and maintenance, this PVC ducting can typically last 5-10 years. Avoid exposing it to UV light or harsh chemicals which can accelerate degradation.
Is there a minimum bend radius I should consider for this ducting?+
To maintain airflow efficiency, we recommend a minimum bend radius of approximately 150mm for the 150mm diameter ducting. Bends smaller than this will significantly reduce ventilation performance.
