AC Infinity CLOUDLINE A4 100mm Fan, 280 m³/h, 10 Modes + Speed Controller

The AC Infinity CLOUDLINE A4 Quiet Inline 100 mm is a quiet and efficient duct fan designed for use in environments with high humidity and dust levels. It features variable speed control and compatibility with control systems, offering the high quality of the CLOUDLINE series at a more affordable price.

The device is designed for efficient yet quiet air circulation in grow tents, grow boxes, and other spaces requiring ventilation. The kit includes a wired controller with a 10-step speed scale, allowing you to adjust operation to current needs.

The PWM-controlled EC motor ensures energy-efficient and smooth operation with low noise levels and minimal heat generation. The mixed-flow design, combining impeller blades with additional aerodynamic elements, maintains adequate airflow even in high-resistance systems.

PRODUCT DESCRIPTION
The fan combines the proven technological solutions of the CLOUDLINE series with robust construction, offering efficient and quiet cooling and ventilation in various applications. Thanks to its mixed-flow design, it maintains a stable airflow even at high static pressure. The motor module with the impeller can be easily detached from the mounting frame, facilitating cleaning and maintenance. The package includes the fan, a speed controller, a UIS adapter (4-pin Molex), a manual, and a set of mounting hardware. The device is part of the UIS™ platform, enabling integration with smart controllers and other devices.

PRECISE SPEED CONTROL
The included controller allows you to set one of 10 speed levels, enabling you to optimally balance performance and noise levels. The PWM-controlled EC motor ensures very smooth operation even at low speeds, without unwanted noise. The device features a settings memory function and a power switch. It can work with temperature and humidity controllers as well as other UIS-compatible control systems.

QUIET AND EFFICIENT DESIGN
The use of a mixed-flow design with additional aerodynamic elements allows for effective operation in installations with limited airflow. Dual ball bearings ensure a service life of up to 67,000 hours and allow for installation in any position. The IP44 protection rating guarantees resistance to dust and moisture, making the unit well-suited for harsher conditions.

WIDE RANGE OF APPLICATIONS
The fan is used, among other things, for cooling electronic equipment (rack cabinets, AV), ventilating living spaces, bathrooms, and attics, as well as in hydroponic systems. Thanks to its quiet operation and speed control, it is a versatile solution for a variety of ventilation systems.
