Inline Duct Booster Fan
A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. Contains an DC-motor with PWM-control for a quiet and energy efficient performance. Includes an intelligent controller that features advanced programming and functions. Complete kit includes one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, installation manual, all necessary mounting hardware, and a corded AC plug adapter.
Intelligent Controller
The controller can be programmed to adjust fan speeds to respond to varying high and low temperatures, and humidity. For ventilation applications, the controller can be set to run continuously, or triggered to run at customizable speeds when given power, due to its backup memory capability. Additional features includes a countdown timer, alarm system, and eco-mode. Includes detachable 12-foot precision water-resistant probe.
Quiet and Energy Efficient Design
Unlike common duct fans that uses an AC-motor which are loud and unmanageable, this duct fan features an DC-motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.

Product Description
The heavy duty axial fan kit is designed for custom projects and as a replacement fan. The high speed 120 by 120 by 38 millimeter 115V AC axial fan is housed in die cast aluminum with thermoplastic blades. Containing long life dual ball bearings, the fan can run continuously for 67,000 hours and be mounted in any direction. Has terminal connectors but can be converted to AC wire-leads with the included power cord adapter. Does not include fan guards or plug cord, please see model HS1238A-X. The AC Infinity axial fan is UL recognized under certificate E503903, and also CE and RoHS certified.
Heavy Duty Construction
The fan’s housing is constructed of die-cast aluminum painted black and able to perform well in harsh environments and withstand shocks. Its impeller and blades are molded with thermoplastic which have a high resistance to flammability. Impedance protected motors contains windings that have a higher resistance to heat during a rotor lock.
Applications
This high speed fan is suitable in applications where maximizing airflow is the primary objective and a louder noise level is tolerable. Popular uses include tanning beds, LED signs, server racks, industrial machinery, arcade systems, and more. Because this is a standard industrial size fan, it can be used to replace fans found in various Samsung and Eaton servers and UPS systems.
