AC Infinity CLOUDLINE H4 4" Inline Fan, Humidity-Proof with Speed Controller

The CLOUDLINE H4 is a humidity-proof inline fan engineered specifically for mushroom cultivation and other high-humidity grow environments. Its IP65-rated housing protects against moisture, dust, and debris, ensuring reliable operation even in harsh conditions. Powered by an energy-efficient EC motor with PWM control, it delivers quiet, consistent airflow to maintain proper humidity, CO₂ levels, and fresh air exchange. The included 10-speed controller allows precise adjustment for any growing stage, while dual ball bearings and a mixed-flow design ensure smooth performance and long-lasting durability. Perfect for grow tents, mushroom fruiting chambers, and indoor cultivation spaces that demand stable, clean airflow.
