Review: This item is a clone of the spider farmers version but 30$ cheaper - This fan is almost exactly the same as the more expensive spider farmers style fan system. The controller works great. The instructions are not the greatest but if you youtube instructions for the spider farmers model it will help you learn this one bc they are the same. Holding up and down arrows will turn the setting off for each setting so if you dont want the alarm on for example just switch to that setting and hold arrow up n down and then it turns it off. Other than that its pretty simple to figure out and my tent has maintained 74 degrees since installing it. Finally a good purchase that was worth the $ spent. So I highly recommend this item
Review: Easy to install and very quiet. - Very easy to assemble, very, very quiet. Can have it on and work on my computer at the same time with no noise pollution. I use it to exhaust my smoke from smoking to the outside without having to use an air cleaner or fan.

## Questions & Answers

**Q: 1. How to determine the required airflow for your room？**
A: Required Airflow(CFM)= Room Volume(cubic feet) × Air Changes per Hour(ACH)/ 60 For example, Room Volume= 20 ft × 15 ft × 10 ft= 3000 cubic feet, Required Airflow=3000 cubic feet × 4 ACH / 60= 200 CFM Then you need to buy a 4" inline fan with 212 CFM

**Q: 2. Is the air pressure related to the distance of the air supply?**
A: Yes, the higher the air pressure, the farther the air supply distance. Hon&Guan EC motor 8 inch inline fan can reach up to 656pa.

**Q: 3. Could you provide a detailed explanation of the different noise levels?**
A: 0-20 dB: Really quiet, almost can't feel a thing. 20-40 dB: Quiet, like whispering softly. 40-60 dB: Regular indoor conversation. 60-70 dB: Noisy, starting to grate on the nerves. 70-90 dB: Very noisy, nerves starting to fray.

**Q: 4. What are the significant advantages of EC motors compared to AC and DC motors?**
A: 1. Higher Efficiency & Low Energy 2. Lower Noise with High Airflow 3. Longer Lifespan 4. Higher Power Density: deliver higher power in a smaller footprint. 5. Environmental Friendliness & Lower Maintenance Costs

**Q: 5. Does it have enough wind power to exhaust the air and impurities from the greenhouse？**
A: At full speed, it can move 830+ cfm without worrying about its lack of airflow, and you can add a filter to facilitate the adsorption of airborne impurities.
