Spread Cooled Air Down the Whole Room, Not Just One Corner
The OptiClimate Air Distribution Tube is a long air sock with holes that distribute cooled air throughout the room. Without one, chilled air drops out of the outlet in a single cold blast and leaves a warm, still pocket at the far end – the uneven airflow that gives you excessive stretch and slow growth at one end and sluggish plants at the other. It is made from high-quality anti-static, light-reflective white LDPE film with a thickness of 180 Mu, perforated with small round holes over a 120° area, so air is directed through one third of the circle and blown out at high velocity.
Key Benefits
- Even distribution along the full 5m or 10m run instead of one cold spot under the outlet
- 120° perforated arc aims air where you want it and keeps velocity high enough to move the canopy
- 180 Mu LDPE film holds its shape when inflated and takes handling
- Light-reflective white surface keeps light in the room rather than absorbing it
- Anti-static, so dust does not cling to the tube
- Sized to the unit: 250mm for OptiClimate Pro 3 3500 and 6000, 315mm for Pro 3 10000 and 15000
How to Use
- Match the diameter to your unit – 250mm for the Pro 3 3500 and 6000, 315mm for the Pro 3 10000 and 15000
- Fit the collar over the outlet spigot and clamp it so no air escapes at the joint
- Suspend the run from the ceiling at or above canopy height, straight and free of kinks
- Rotate the tube so the 120° hole pattern faces the way you want the air to travel
- Choose the length to suit the room: 5m for a single bay, 10m for a longer run
- Check it inflates fully once the unit runs; a slack tube means a restriction or a leaking collar
