The CLOUDLINE A4 is a 4-inch inline duct fan designed to quietly ventilate grow tents, rooms, and closets. It can support air-circulation and exhaust applications, including cooling grow spaces, exhausting odors, transferring heating or cooling, and cooling AV equipment areas.
The system combines a mixed-flow design with an EC motor and PWM control to deliver up to 165 CFM of airflow. Its included wired controller provides 10 speed settings, a power switch, and backup memory for retaining the last selected speed.
Key Features
Quiet Ventilation: Designed to ventilate grow tents, rooms, and closets while supporting air-circulation and exhaust projects.
10-Speed Controller: The included wired controller provides 10 fan-speed options for adjusting airflow and noise levels.
Backup Memory: Retains the last selected fan-speed setting after the fan is powered down.
EC Motor: Uses PWM control for precise, quiet, and energy-efficient operation, including performance at low RPM speeds.
Mixed-Flow Design: Uses a stator blade and dual hydrodynamic wind circles to maintain airflow in high-static-pressure applications.
Dual Ball Bearings: Rated for a 67,000-hour lifespan and allow the fan to be mounted horizontally or vertically.
Vibration-Reducing Base: The plastic mounting base helps diminish noise caused by fan vibration.
Detachable Motor Box: The motor box containing the impeller and blades can be removed from the mounted frame for cleaning and maintenance.
Ingress Protection: IP44-rated construction provides resistance to dust and liquids.
UIS™ Platform: Designed as part of the UIS™ platform for integration with compatible grow devices and smart controllers.
