  • 【With 433 Wireless Remote Control】: The Qicrafe inline exhaust fan, which can be remotely controlled over a distance of up to 100 meters without obstructions, is ideal for air circulation in spaces such as grow tents, hydroponic grow rooms, bedrooms, attics, kitchens, bathrooms, basements, and more.
  • 【Five Key Features】: The inline exhaust fan comes with a temperature and humidity controller, allowing you to set both current temperature and humidity simultaneously. It includes a countdown timer function and a one-touch on/off switch. The countdown can be set for up to 9 hours and 50 minutes. The intelligent inline exhaust fan activates automatically to expel heat, reduce humidity and smoke, and improve air circulation.
  • 【Exclusive 2025 New Design】: Developed based on extensive user feedback, this easy-to-operate controller features the new AHT20 sensor chip with a waterproof and breathable membrane. It offers greater accuracy and extended lifespan, eliminating worries about inaccurate temperature and humidity readings. Comes equipped with a 2-meter sensor probe.
  • 【Powerful Motor and Airflow】: The duct fan is equipped with a high-performance pure copper motor with high rotational speed, delivering a maximum airflow of up to 200 CFM. It features a waterproof rating of Level 4 and a 4-inch vent, ensuring rapid cooling, dehumidification, and exhaust.
  • 【Usage Tips】: You can simultaneously set humidity and temperature activation, as well as delay functions. When the current environment reaches the set humidity and temperature levels, the inline duct fan will automatically start. If the humidity drops 4% below the set level or the temperature falls 2°F below the set point, the fan will automatically stop, ensuring energy efficiency and eco-friendliness.

this fan is a solid choice for enhancing ventilation in small to medium-sized areas, especially where precise environmental control is needed. However, for larger spaces or continuous heavy-duty use, you might want to consider more robust options.

It's the only one I've ever owned, but foe the price this thing is a beast! Use it for my CO2 Laser. Pulls the smoke out like it's supposed to.

DO NOT BUY.I bought this and installed it. It worked for exactly 30 days and I returned it telling Amazon it stopped working. They accepted the return and said they understood and I would get a full refund. Today they received the item, but charged me almost $13 in damages fees for an item they knew stopped working by no fault of my own.Spend your money on a better product.

Speed control option is separate. You have to choose between sensors and speed control. For my needs, air purification, speed control is essential but currently there is no option to buy the speed control variant.

Second time I've bought this fan each time it works for about 5 minutes and then the fan completely stops working but the power stays on I bought it the second time because it has everything you need but it's a waste of time Do not recommend
