The CLOUDLINE H4 is a 4-inch inline duct fan designed to ventilate mushroom-growing spaces, grow tents, grow rooms, and fruiting chambers. Its IP65-rated construction resists dust, debris, moisture, and spores in high-humidity environments.
A 10-level speed controller provides precise airflow adjustment and retains the last selected setting after power is interrupted. The mixed-flow design, EC motor, and PWM control deliver up to 212 CFM of airflow with a listed noise level of 27 dBA.
Key Features
-
High-Humidity Ventilation: Designed for mushroom cultivation and fungiculture to ventilate grow spaces while supporting fresh air exchange and humidity and CO₂ management.
-
IP65-Rated Construction: Sealed to resist dust, debris, moisture, and spores in high-humidity environments.
-
10-Level Speed Controller: Provides 10 precise fan-speed settings for adjusting airflow and noise levels.
-
Backup Memory: Retains the last selected fan-speed setting when power is interrupted.
-
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 deliver airflow in applications where air movement is restricted.
-
Dual Ball Bearings: Rated for a 67,000-hour lifespan and allow the fan to be mounted horizontally or vertically.
-
Detachable Motor Box: The motor box containing the impeller and blades can be removed from the mounted frame for cleaning and maintenance.
-
UIS™ Platform: Designed as part of the UIS™ platform for integration with compatible grow devices and smart controllers.
