  Product Description

  An inline duct fan specially designed for mushroom cultivation and fungiculture to quietly ventilate grow tents, grow rooms, and mushroom fruiting chambers. By installing this fan, you can control humidity and CO₂ levels to keep them stable while ensuring fresh air exchange in these spaces. It is built with IP65-level sealing that lets you place it in harsh environments, resisting moisture and spores. It also features a fan speed controller with 10 exact levels to produce your ideal airflow. This precision output is powered by the inline fan’s EC motor that utilizes PWM control to operate quietly and energy-efficiently. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to unite with the AC Infinity app over WiFi to achieve your ideal environment.

  Precise Speed Controller

  The speed controller lets you set between ten precise fan speed levels to optimal noise and airflow levels in mushroom-growing environments. This exact airflow control is enabled by the cutting-edge EC motor that is precisely controlled using PWM (Pulse Width Modulation). This allows it to run smoothly at extremely low RPM speeds without generating motor noise. It also features backup memory that retains the last speed setting whenever power is cut off from the controller.

  Quiet and Energy-Efficient Design

  This inline fan utilizes a mixed-flow design with a stator blade and dual hydrodynamic wind circles, enabling it to deliver airflow even in applications where air movement is restricted. In addition, it is built with dual ball bearings that have a 67,000-hour lifespan, allowing you to mount it in any direction. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance.
