AC Infinity Cloudline PRO S-Series Inline Fan (with Speed Controller)

Powerful EC Extraction with 10-Speed Precision Control

The AC Infinity Cloudline PRO S-Series Inline Fan pairs a powerful EC-motor inline fan with an included 10-speed intelligent speed controller, giving fine control over extraction without needing full sensor-based automation. It is UIS-upgradeable, so you can bring it into an automated temperature, humidity or VPD setup later by connecting it to a compatible AC Infinity UIS controller. Dual ball bearings and a mixed-flow blade give it a long service life and strong airflow at lower noise than comparable AC-motor fans.

Key Benefits

• Powerful EC motor for efficient, high-airflow extraction and heat removal
• 10-speed intelligent controller included for precise manual adjustment
• UIS-upgradeable for automated temperature, humidity or VPD control later
• Five sizes: 100mm (~205 CFM / 348 m3/h), 150mm (~402 CFM / 683 m3/h), 200mm (~807 CFM / 1,371 m3/h), 250mm (~1,200 CFM / 2,039 m3/h) and 315mm (~1,604 CFM / 2,725 m3/h)
• Quieter running than comparable AC-motor fans at similar airflow
• Dual ball bearings rated for a 67,000-hour L10 life

Tent Running Warm, Humid or Smelly at Any Fan Speed?

A fan too small leaves a tent muggy, warm and holding onto smell; one oversized and run flat out wastes energy and dries things out too fast. The S-Series lets you pick the right size for the space and fine-tune across 10 steps, balancing extraction, noise and energy use instead of being stuck at one fixed speed.

How to Use

• Fit the fan into your ducting run, typically drawing air through a carbon filter for odour control
• Connect the supplied 10-speed controller and set a level that holds temperature and humidity in check
• Raise speed in summer or heavy flower, lower it in winter to cut noise and energy use
• To automate later, connect the fan to a compatible UIS controller instead
