Designed to quietly ventilate tents, exhaust odors, transfer heating/cooling to rooms and cool AV cabinets. It features the same build quality and innovations as the CLOUDLINE series delivered in a value package. Includes a wired 10-speed fan controller; also compatible with all CLOUDLINE series smart controllers. Mixed-flow design combined with an EC powered motor for truly quiet and energy efficient performance. Duct size: 10 cm | Dimensions: 17.5 x 30.2 x 18.8 cm. | Airflow: 165 CFM | Noise: 29 dBA | Bearings: Double Ball Product Description: This inline fan system includes CLOUDLINE's core innovations and premium build quality to bring you a value package. Designed to quietly cool tents, rooms and closets, and provide ventilation in various air circulation and exhaust projects. With an in-line mixed flow design, the duct fan can maintain airflow even in high static pressure applications. The motor box containing the impeller and fan blades can be detached from the assembled frame for easy cleaning and maintenance. The complete kit includes an inline fan unit, a speed controller, UIS to 4-pin Molex dongle, installation manual and all necessary mounting hardware. Precise Speed Controller The speed controller allows you to adjust the duct fan speed to optimal noise and airflow levels for various environments. This inline fan is equipped with the same CLOUDLINE series EC motor that is precisely controlled by PWM (Pulse Width Modulation), allowing it to run smoothly at extremely low RPM speeds without generating motor noise. Ten speed options are available with power switch and backup memory. This model can be connected to the following smart controllers to share the same programming and power supply as other EC motor CLOUDLINE fans: B-Series Temperature Controller Temperature and Humidity Controller T Series Driver 67 Quiet and Energy Efficient Design The inline fan features a mixed-flow design using a stator blade and dual hydrodynamic wind circles. This gives it high static pressure, allowing it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours, allowing the duct fan unit to be mounted in any direction. In addition, the inline fan is constructed with a plastic mounting base to decrease noise as a result of fan vibration. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments. Applications This quiet inline fan system is found more in tents and hydroponic rooms to provide cooling and ventilation to plants. Its low noise level and advanced control functions make it suitable for bathroom and attic environments as well as for cooling AV equipment rooms, cabinets, racks and cabinets.
