Cultiv8 Inline Fan (100mm / 150mm / 200mm)

What is the Cultiv8 Inline Fan used for?

The Cultiv8 Inline Fan is a simple inline duct fan ideal for small to medium grow tents. It's best used for intake, light-duty exhaust, air circulation, or ventilation in drying and propagation spaces. It can also help bring cool air in at floor level or maintain negative pressure in a grow room.

Is Cultiv8 Inline Fan a booster fan or high-pressure fan?

It’s a booster-style axial fan—great for high airflow through short, low-restriction duct runs. It’s not designed for high-pressure tasks like pushing through long ducting or dense carbon filters.

What airflow can I expect from different fan sizes?

The 100mm model typically moves around 140 m³/h, the 150mm about 330 m³/h, and the 200mm around 420 m³/h. Actual airflow depends on your setup, including ducting length and filter use.

How much power does the Cultiv8 Inline Fan use?

The 100mm model draws around 22W, the 150mm about 35W, and the 200mm about 37W. It runs on standard 220–240V AC power at 50Hz in Australia.

Is the Cultiv8 Inline Fan quiet?

For a metal booster fan, it’s relatively quiet—especially when used with short duct runs. Excess noise usually comes from install factors like poor mounting, air leaks, or crushed ducting.

Can I use a speed controller with the Cultiv8 Inline Fan?

It doesn't come with one, but some AC fan controllers may work. Avoid cheap dimmers, as they can cause humming or poor performance. For precise control, consider upgrading to an EC fan system.

How should I install the Cultiv8 Inline Fan?

It can be mounted horizontally or vertically. Use rubber straps or isolators to reduce vibration. Most models include brackets or mounting points, and built-in flanges make ducting connection easy.

What type of ducting works best with this fan?

Use short, straight, smooth ducting in the matching size: 100mm, 150mm, or 200mm. Reducing duct size or using silencers will increase resistance and reduce airflow.

Why does airflow feel weak or uneven?

Performance drops with long or bent ducting, carbon filters, air leaks, or restricted intakes. For strong airflow, keep duct runs short and reduce restrictions wherever possible.

How do I clean and maintain the fan?

Unplug the fan before cleaning. Wipe dust from the blades and housing occasionally. Keep prefilters clean and check for dust buildup if airflow drops or the fan sounds louder than normal.

What fan size should I choose for my grow tent?

100mm is usually fine for tiny or propagation tents. 150mm suits up to 1.2m x 1.2m tents with light loads. 200mm can be overkill in small spaces unless paired with a speed controller.

Can I run the Cultiv8 Inline Fan 24/7?

Yes—these fans are commonly used for continuous operation. Running constantly at low load helps maintain stable humidity and odour levels better than on/off cycling.

What is the Cultiv8 Inline Fan made from?

It typically features a steel body, steel blades, and a ball-bearing motor for long-term reliability. It’s suitable for humid grow spaces, garages, and general ventilation—just avoid direct water contact.

Does the Cultiv8 Inline Fan come with a warranty?

Yes—it's generally sold with a 12-month warranty, though warranty handling may vary by retailer.
