Upgrade your ventilation setup with our premium Combi Ducting the ideal solution for indoor grow environments where durability and flexibility matter. Designed for grow rooms to be used with in-line fans, carbon filters, hydroponic systems, grow tents, HVAC systems, greenhouses, bathrooms, kitchens, offices, AV closets and many other ventilation applications this ducting combines the strength of aluminium with the resilience of PVC for long-lasting performance.
Multi-size options โ Supplied in various lengths and diameter sizes.
Enhanced durability โ The aluminium inner layer plus heavy-duty PVC outer shell deliver significantly greater tear-resistance than single-layer foil ducting.
Noise-reduction โ Dual-layer construction and smooth internal surface help reduce airflow noise compared to basic aluminium flex.
Shape-stable spiral design โ Reinforced with spiral-wound wire to maintain cross-section under compression or bending, ensuring efficient airflow
Light-leak prevention โ The opaque outer layer ensures full light-proofing, which protects dark-period integrity and reduces unwanted internal reflections
Flexible installation โ Can be installed with no special tools easily stretched to minimise folds (which reduce resistance) or concertina down for compact routing.
Flame-resistant material โ Designed for HVAC/grow-room use, meeting relevant flame-retardant specifications.
Frequently Asked Questions
Q: Can this ducting be used with any in-line fan or carbon filter?
A: Yes provided the flange diameter matches the ducting diameter you select. The product is compatible with standard extraction systems.
Q: Does the ducting significantly reduce noise compared to standard aluminium flex?
A: Yes its dual-layer construction and smooth interior design contribute to lower noise levels than simple single-layer aluminium ducting.ย
Q: Is this ducting fully light-proof?
A: Yes the outer black PVC layer prevents light leakage, making it suitable for grow-rooms where light control is essential.
Q: How flexible is the ducting for routing around corners or tight spaces?
A: It is quite flexible thanks to the spiral-wire helix and flexible outer layer. It can be bent around corners and compressed to a short length if needed.
Q: Is the product fire-safe for indoor grow setups?
A: Yes the material is flame-resistant and designed for horticultural ventilation use, meeting flame-retardant specifications.ย
Q: What happens if the ducting is left folded or pleated instead of fully extended?
A: For maximum effectiveness and to stop dust collecting in the ducting, always make sure your ducting is fully extended. Folding or pleating the duct increases air resistance and noise, reducing system efficiency.ย
