Combiconnect Air Connections 315 mm 10 m. is a semi-rigid flexible duct designed to move large volumes of air in Indoor cultivation. Laminated aluminum and polyester with steel spiral and PVC coating; quick installation, long runs, and reliable sealing with clamps or aluminum tape.

The Combiconnect Air Connections 315 mm 10 m. duct combines flexibility and robustness to design efficient ventilation networks in cabinets and rooms. The multilayer wall of aluminum + laminated polyester houses a steel helix that keeps the section open even in wide curves, reducing pressure losses and preventing collapses.
The outer coating in PVC protects against friction, moisture, and abrasions, providing mechanical resistance in demanding installations.
The Ø315 mm diameter fits with extractors, carbon filters, silencers, elbows, and large-format wall sleeves, sealing joints with metal clamps or reinforced aluminum tape to achieve airtightness.
The 10 meter roll minimizes joints and leakage points, promoting a stable flow with less turbulence. Within cannabis cultivation accessories, this duct is key to maintaining negative pressure, controlling odors, and stabilizing temperature and humidity.
At Hydroponics Blanes, a Grow Shop in Spain recognized as a trusted Grow Shop, it is available with technical advice and discreet shipping, as well as options in cheap indoor grow tents and all the elements to complete the installation.
In professional Indoor cultivation, a large diameter duct ensures continuous exchange without restricting the flow. Combiconnect Air Connections 315 mm 10 m. allows you to trace straight runs and gentle curves, connecting extractor, filter, and outlets with few joints.
The result is a more homogeneous microclimate, with less aerodynamic noise and better carbon filter performance.
It is used to convey air in high-flow extraction and intake circuits. It facilitates controlled turns without collapsing the section, provides mechanical resistance through the steel spiral, offers external protection with PVC, and allows for quick perimeter sealing to maintain pressure and prevent leaks.
This indoor cultivation accessory integrates with 90º elbows, Y/T branches, reducers, and Ø315 wall sleeves. The semi-rigid construction preserves the duct geometry, reduces vibrations, and limits turbulence compared to overly soft tubes. Ideal in flowering rooms, drying rooms, and technical rooms where stability and constant flow are critical.
It is used to connect inline extractors with carbon filters, divert outlets to the facade or roof, supply intakes, and organize ventilation networks with several branches. It also allows the creation of main collectors that distribute air to different areas, maintaining balance between lines and minimizing losses.
1) Measure the route and cut the necessary length; protect the end after cutting.
2) Present Combiconnect Air Connections 315 mm 10 m. at extractor, filter, elbow, or branch inlets, respecting wide bending radii to avoid restricting the passage.
3) Secure with metal clamps of Ø315 or reinforced aluminum tape; perform perimeter sealing for maximum airtightness.
4) Support long sections with clamps or hanging straps to eliminate flapping and vibrations.
5) Turn on the system and check for absence of leaks, abnormal noises, and flow drops; adjust alignments if necessary.
High flow capacity in main lines; semi-rigid structure that does not collapse in curves; steel spiral for stability; PVC coating that protects the laminate; fewer joints per 10 m roll; quick installation with clamps/tape; integration with cannabis cultivation accessories and compatibility with cheap indoor grow tents.
