An inline duct fan designed to improve airflow in heating and air conditioning applications, and ventilate home rooms like attics, workshops, bathrooms, and kitchens. Each fan uses an easy-to-use knob controller that adjusts fan speed for your specific airflow boosting needs. It features a unibody framework that helps reduce vibration and ensures smooth and low-resistant airflow. The matte black steel cylinder is fluted and ridged for easy and secure installation in-between ducting. Its balanced steel blades have a 67,000-hour lifespan and spin using permanently lubricated dual-ball bearings to eliminate regular maintenance. The dual ball bearings also allow this fan system to be mounted horizontally or vertically. This kit includes one AC powered booster fan, a speed controller with a power plug, mounting screws, and a cable management set.
The inline variable speed controller can control the fan’s speed and turn it on or off. Turning the knob will increase or decrease the fan speed and optimize airflow and noise levels for your application. It uses a female aviation plug with a metal retainer, tightly securing its connection to the duct fan.
This versatile inline booster fan is made to be installed in-between ducting for various applications that need improved air delivery. In households, it boosts airflow from HVAC units to remove stale air and odor, ventilating attics, workshops, kitchens, basements etc. In grow tents, grow rooms, and indoor gardens, it’s primarily used as an intake fan to bring in fresh air. Please note this booster fan cannot be used standalone in high static pressure applications like room ventilation. Additionally, it is not suitable for use in applications with restricted airflow like systems that use carbon filters. For higher performance, see the CLOUDLINE Series.
A line of duct fans designed to be set in between or at the ends of ductwork to increase airflow in existing HVAC projects like grow tents and other ventilation setups.
Premium Solid Steel Body
This booster fan boasts a matte black aesthetic that expresses the heavy-gauge construction and its high quality. The galvanized steel body has no folded seams, enabling the fan to perform with low noise and no rattling. It also features crimped ridges on the exhaust end for a tight, secure grip on your flex or rigid ducting.
All models include a speed controller to optimize airflow and noise. The soft rotating knob provides ease of use and quick responses to changing conditions.
High Performance Motor
Uses an AC motor that spins smoothly and relatively silent. Capable of high airflow boosting in applications like active intake for grow tents.
Features a 67,000 hour lifespan, using balanced steel blades and lubricated ball bearings that eliminates the need to maintain the fan.
Tight and Secure Lock
The aviation ports are easy to plug in and tightly secures each other using a retainer that also keeps moisture, dust and debris out.
