FAQs

What makes the CLOUDLINE fan so quiet and powerful?+

The CLOUDLINE fan uses a mixed-flow design with stator blades and dual hydrodynamic wind circles. This allows it to move a high volume of air (352 CFM) through restrictive setups like carbon filters while maintaining a very low noise level of just 34 dBA.

What size grow tent is this 6" kit suitable for?+

This 6" kit is ideal for medium-sized grow tents, such as the AC Infinity Cloudlab 4' x 4' or the Cloudlab 5' x 5'. Its 352 CFM rating provides ample air exchange for effective temperature, humidity, and odor control in these spaces.

How often does the carbon filter need maintenance?+

The included machine-washable pre-filter cloth should be cleaned every few weeks to prevent dust buildup. The filter itself has reversible flanges, allowing you to flip it to maximize its lifespan. The high-grade Australian charcoal provides up to 33% longer performance than standard filters.

Can I upgrade the fan controller?+

Yes. While this kit includes a 10-speed manual controller, the CLOUDLINE fan is part of the UIS platform. You can easily upgrade to a smart controller, like the Smart Controller 69 Pro, to automate fan speed based on temperature and humidity triggers.

How do I get the best results from my ventilation kit?+

For optimal performance, ensure your ducting has minimal bends and is pulled taut to reduce air resistance. Position the carbon filter at the highest point inside your tent to capture rising heat and odors. For a complete walkthrough, check out our in-depth guide on AC Infinity filter kits.
