These 2nd Generation Oscillators are the best we've ever used.  No more clicking noise, these just work.  A next-gen clip fan designed from the ground up to provide precise air circulation for all stages of a plant’s growth. Utilizes a cutting-edge EC motor with PWM control to access a full range of fan speeds, from gentle breezes to a powerful airflow. The ten speed levels are shown with a circular LED display that dims after fan speed is set to leave your plant’s light cycle undisturbed. Adjustable head tilt and swiveling arm provide flexible directional airflow options while the additional oscillation option adds automatic circulation at a wider range. Features a heavy-duty clamp that tightly grips onto grow tent poles of all sizes for a secure vertical hold. Each unit is IP-44 rated to be highly resistant to humidity and temperature. Can be powered through a standard outlet with its 8-foot power plug cord. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment. SMART CIRCULATION CONTROL Features a cutting-edge Electronically Commutated (EC) motor, controlled digitally using precise electronic pulses. This PWM technology enables the fan to access the full range of its speed 0 to 100%. Set the optimal circulation for any plant growth stage, from ultra-gentle breezes for germination and seedlings, to a powerful airflow for vegetative and flowering. Includes a corded adapter that can be used to connect to AC Infinity smart controllers to access climate triggers, grow cycles, scheduling, and more. Controllers are sold separately. RATED FOR GROW ENVIRONMENTS This series was designed from the ground up for a grow space environment. All components are specially sealed to IP-44 standards to be highly resistant to liquids and dust. As a result, the system can maintain peak performance and a long lifespan even in harsher surroundings with high humidity and temperatures. Designed with an EC-motor to provide precise air circulation for all stages of a plant’s growth. Automatic oscillation with digital 10 speeds, producing gentle breezes and powerful airflow. IP-44 rated specifically for the grow environment to be resistant to high humidity and heat. Connects with smart controllers to access climate triggers, grow cycles, scheduling, and more. Impeller: 6.5” | Airflow: Up to 315 CFM | Auto Oscillation | Fits all grow tent poles sizes
