Its energy-efficient design and durable construction make it a reliable choice for anyone looking to enhance their indoor air quality.

## Description

Inline Duct 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 EC-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 all necessary mounting hardware. 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 include a countdown timer, alarm system, and eco-mode. Includes a detachable 12-foot precision probe that is water-resistant. Quiet and Energy Efficient Design Features an EC-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.

## Features

- MICROMALL 6” Inline Duct Fan are used in indoor grow facilities and vertical farms, heating and cooling transfer, commercial drying and air filtration applications. Our inline blowers can also create negative pressure environments, simulate wind, exhaust odors and smoke as well as intake fresh air from outdoors.
- SMART PROGRAMMING: Intelligent controller with temperature and humidity programming, fan speed control, timer, and alarm system.The controller has precise temperature and humidity sensors on a 12-foot wired probe.
- QUIET AND ENERGY SAVING PERFORMANCE IS VERY GOOD: The mixed flow design and the PWM controlled EC motor can be controlled using precise electronic pulses and intelligent programming. This can make the inline fan run more quietly and reach low speed without generating noise or heat.
- PACKAGE DETAILS: Quiet 6” Inline Duct Fan, smart programmer, wired sensor probe, AC power plug, two conduit clamps and required installation hardware.
- DUCT DIAMETER: 6” (150mm) — Airflow: 370- 402 CFM —Power: 50W —Input Voltage: AC110~220V, 50/ 60Hz —Speed: 2500RPM/min —Noise: 32 dBA —Pressure: 502 Pa — Bearings: Dual Ball —Size: 12.48x 8.03x 9 in. —2 Years Warranty.

## Questions & Answers

**Q: If it controls humidity do you still need a humidifier in your tent?**
A: The humidity control aspect is meant to remove humidity, not add it. An exhaust fan would naturally remove humidity by sucking t out of the tent. Downside is if you want the temp at 75 and the humidity at 50%, and the humidity rises above 50%, the fan would kick in, which would ultimately drop the temp and humidity at the same time.

**Q: What parts of this are metal and how much heat can it handle**
A: You can set the high temperature operation on the controller, if the set temperature is 86℉ and the room is over 86℉, the fan will start to run, the controller will control the speed of the fan according to the temperature of the room, the fan Airflow: 370 CFM

**Q: Would it work to install this fan through the house wall so that I can bring the cool, outdoor evening air indoors without having the windows open.**
A: You can do this.But ,I do not recommend bringing out door air directly into the house, it has to be conditioned first and its often better to just recirculate air. Depending on the amount of airflow you were looking for, that would be the determining factor. These units move quite a bit of volume of airflow and are primarily used in filtering or moving air from room to room.

**Q: How do you calibrate the temp probe via controller?**
A: There is a digital display

    Perfect for my needs
  

*by S***. on Reviewed in the United States on February 19, 2021*

I have 2 grow tents 2'x2'x4'T & 3'x4'x6'T. I initially bought 1 for my small tent & was so impressed I purchased a second for my larger tent. Both tents stay within the parameters I have set them too which has increase my yields nicely. I highly recommend this for any size tent within the parameters of mine.

*by A***R on Reviewed in the United States on December 3, 2021*

I like the fact that it has a digital thermostat. It's some wat quite it can be installed with one person but better if u got help.

### ⭐ 1.0 out of 5 stars







  
  
    Very cheap. Might as well spend the extra $40 for a legit one.
  

*by M***N on Reviewed in the United States on April 19, 2021*

The rivets that held the fan assembly to the minting bracket immediately popped off when I went to install the unit. I zip tied the fan together got it installed and the humidity controller wouldn’t power on.. it was a complete waste of time and effort. Word of advise don’t Rivet metal to plastic and expect it to hold.
