I Tested And Reviewed 10 Best Fan To Dry Out Crawl Space (2023)

I am extremely satisfied with the performance of this unit so far. I am using it as an attic exhaust fan in a gable vent and it works brilliantly. During the summer months, I have set the thermostat to a specific temperature and the humidistat to "On" to keep the attic cool and prevent condensation. In the winter, I adjust the thermostat to a lower setting and set the humidistat accordingly to prevent condensation buildup. The sound level is pleasingly low and the airflow is excellent.

Although I did not use it for its intended purpose, I placed it in a window to remove fumes from my laser engraver and it works flawlessly. It operates quietly and has a strong suction power.

Installation is a breeze as long as you have enough space around the vent opening and are comfortable drilling holes in masonry. I bought this unit because our house had previous mold issues in the crawl space, and I wanted extra ventilation for peace of mind. The installation process involved marking the holes on the wall, drilling them with a masonry bit, and securing the unit in place. Since there was an outlet nearby, I only needed a short, heavy extension cable to connect it. Although I plan to unplug it during the cold winter months, it's reassuring to know that it has a low temperature lockout feature.

Before installation, I tested the unit and found it to be slightly noisy. However, considering the amount of air it moves, the noise level is not excessive. Once in place in the crawl space, there is a slight noise audible outside next to the vent, but it is not loud enough to cause any concern, especially since it is located next to the HVAC outdoor unit. Additionally, it is situated right under our laundry room, but I cannot hear it running from inside the house.

I am very pleased with this unit and the fact that it provides excellent ventilation for my space. It is capable of pushing a significant amount of air, making it the perfect solution for our crawl space. In fact, I am now considering purchasing another unit to ventilate our attic as well. The installation process was easy, and it can be done by a single person due to its lightweight design. The control panel is simple and straightforward – just plug it in and turn it on. I highly recommend this unit if you are in need of effective and efficient ventilation.

I recently purchased this fan with the intention of using it to vent out a small closet under the stairs. Unfortunately, I discovered that it only activates based on humidity levels or temperature levels, and since I don't have a humidity issue in the closet, it won't work for my specific needs. However, I must say that I am impressed with the sturdiness of this fan. Given its affordable price, I had expected it to be flimsier, but the metal frame is solid and durable.

Another reason I bought this fan was to address the issue of cigarette smoke in my roommate's bedroom. Despite my repeated requests, he continues to smoke indoors, and the smell permeates the rest of the house. This fan has been a lifesaver in that regard. I installed it in the scuttle hole cover of his room, and it effectively keeps the stinky smoke from spreading. I'm extremely pleased with this purchase, although I do wish I could find a way to convince my roommate to move out instead!

In addition to these uses, I also installed this fan in a chicken coop that required ventilation. What I love about this fan is that it can be thermostatically controlled, allowing me to set it to turn on before the coop gets too hot or humid. It has made a significant difference in keeping the coop cooler and drier. Although it is a little loud, I don't spend much time in the coop, so it's not a major issue for me. The installation and adjustment process was straightforward, and the overall quality of the product is excellent, especially considering its reasonable price.

I should also mention that this fan is relatively quiet, making it suitable for use in a studio. While it's not completely noiseless, it doesn't disrupt live recording sessions. I personally chose to hardwire it instead of using the provided outlet plug, and it has been performing well in ventilating my studio.

In terms of installation, it took me around 20 minutes to set up and get the fan working properly. Overall, I am highly satisfied with this product. It is not only effective in its functionality but also comes at an affordable price point.

I purchased this ventilation fan to address the heat buildup in my garage during the summer months, specifically to cool down my bitcoin mining rig. The unit has exceeded my expectations in terms of performance and ease of use. The controls are simple and straightforward, allowing me to easily adjust the settings as needed. The installation process was a breeze, and I was able to set it up without any complications.

In terms of functionality, this fan works exceptionally well. I placed it in my garage to vent the hot air out through the ceiling vents, and it has done an excellent job in keeping the space cool. With its flat side, it seamlessly mounts flush to the ceiling over the vent hole. Despite running on a medium low setting, the unit pushes a significant amount of air, effectively reducing the ambient temperature. Before installing the fan, my garage would reach temperatures over 100 degrees Fahrenheit, but now it consistently stays around 85 degrees Fahrenheit. I believe it has the potential to cool the space even further if I were to increase the fan speed, but for now, it serves its purpose of providing circulation in the garage.

While there are numerous options available when it comes to attic fans, I am pleased with my choice. The fan effectively meets my needs by providing proper ventilation to prevent moisture and mold buildup. It moves a substantial amount of air, ensuring good circulation throughout the attic. Although it does produce some noise when running, it is not overly bothersome. The build quality is sturdy, and the installation process was hassle-free.

I recently purchased the ventilation fan for my storm shelter in the basement, and I am quite impressed with its performance. Although I haven't installed it yet, I was able to test it out uninstalled, and I must say that it exceeded my expectations. One of the standout features of this fan is its quietness. Even at full speed, the motor operates with minimal noise, comparable to a standard box fan on low. This makes it perfect for use in areas where noise might be a concern, such as a storm shelter or a crawl space.

Another aspect that I appreciate about this fan is its power. It moves a significant amount of air, which is essential for proper ventilation in my storm shelter. With its ability to circulate the air effectively, I can rest assured that the air quality in my shelter will be maintained at a high level.

Furthermore, the installation process was a breeze. I simply pre-drilled the necessary holes, screwed the fan in place, and plugged it into a standard 110V outlet. I particularly appreciate that there was no complex wiring involved, as I would have been hesitant to purchase it otherwise. Within just 30 minutes of unboxing the fan, I had it up and running, ready to provide efficient ventilation.

Though I have yet to permanently install the fan, I am confident that it will perform exceptionally well. Its ability to move air and maintain a quiet operation make it an excellent choice for various applications. Whether it's for ventilating a shed or improving air quality in an attic, this fan offers a reliable solution. I would highly recommend considering this product for anyone in need of a powerful and quiet ventilation fan.

I recently installed two fans in my crawlspace to improve air circulation and eliminate stagnant air. I must say that I am highly impressed with the results. The fans are so quiet that you can barely hear them from outside the house. Not only has the crawlspace become much drier, but the air also feels fresher and the unpleasant smell has significantly improved. I would rate the installation process with 4 stars, as I found the flange or cover plate to be slightly smaller than I had hoped, making it a bit challenging to install. However, it's worth mentioning that working in a small crawlspace is inherently difficult, so this was expected.

One thing that was not immediately evident from the product description is that the controls and power cord are located towards the crawlspace, allowing for exhaust through the plain-looking cover. Unfortunately, I don't have power in my crawlspace, so I had to make a small modification. I removed 16 small screws and flipped the fans, placing the controls and power cord on the outside. This way, I could protect them from the weather. Although after the reversal, the unit produced a noticeable whistle, I was able to reduce it significantly by cutting out the sheet steel grids.

I initially installed these fans to circulate fresh air beneath my raised house. The installation process was relatively easy, although I would advise carefully considering the size of the unit, as it has a fairly large footprint. I had to make some customizations to fit it properly. After a year of continuous operation, I can confidently say that these fans have been doing an excellent job, even in harsh environmental conditions. I have noticed a significant improvement in both air quality and humidity levels since their installation. I highly recommend these fans, especially for those living in humid areas.

This is a good fan, but I want to emphasize the importance of measuring your foundation block properly. In my case, the hole was 8×16-1/2", and I didn't feel comfortable drilling into the corner. I ended up purchasing some treated plywood to create a larger base. The fan itself is remarkably quiet, making it virtually unnoticeable from inside the house. However, after almost two years of use, one of the fans stopped working. Fortunately, I was able to find an aftermarket fan for a reasonable price of $19, and now everything is working perfectly again.

I recently purchased and installed the crawl space fan to help with the high humidity in my crawl space. After installing a dehumidifier and this fan, I noticed a significant decrease in humidity levels overnight. The controls on the fan are very user-friendly, making it easy to set manually or adjust to a specific humidity level.

The fan itself is of high quality and comes with a controller that allows you to set it to turn on/off automatically based on humidity levels. I didn't personally test the humidity setting, but the fan runs smoothly and cycled on/off based on the humidity levels in my living room. The fan has a high power of over 500 cfm, which means it's not completely silent when running.

The fan is made with a stainless steel faceplate and comes with clear instructions and installation hardware. Although I don't have a crawl space, I found other uses for this fan, such as improving circulation in the lower level of my house, exhausting the garage on hot summer days, or reducing AC usage by exchanging hot air inside the house with cooler air outside.

I must mention that the fan is well-built and comes well-packaged. The bearings are smooth, and I believe it will last for years. I checked the power consumption, which is 64 watts and 0.8 amps. The motor efficiency is 67 percent, although I'm not entirely sure how this affects its performance. Overall, I consider it to be a good product.

One reviewer mentioned using the fan to address condensation issues in their crawl space. They installed it near the HVAC unit, where most of the condensation occurs. After a few days, they noticed a significant improvement, with less accumulation of water and a decrease in the musty smell. However, they mentioned that the unit is noisy and can be heard in the room directly above the fan.

I recently purchased this fan to help with ventilation in my attic, and I must say, it has exceeded my expectations. I had been searching for a fan that would automatically turn on and off based on temperature changes, and this fan does exactly that. No need to hire an electrician or go through complicated installations – it's a plug and play solution.

Not only does this fan keep my attic cool, but it also helps me save electricity by reducing the need for air conditioning. I was pleasantly surprised to discover that it can also be activated by humidity levels, making it perfect for basements or crawl spaces. Plus, it's weather resistant, so I don't have to worry about it getting damaged.

Another user mentioned that they installed this fan in their crawl space to combat humidity and odor. While they did mention that they needed multiple fans to achieve the desired results in their larger crawl space, they did notice a slight drop in humidity after a month of use. However, they experienced an issue with the fan shutting off and being unable to power it back on.

But here's the good news – the company, Alor Air, reached out to the user personally and provided excellent customer service. They promptly sent a replacement fan free of charge and went above and beyond to assist the user. This level of dedication and support deserves five stars.

I recently installed this fan in my crawl space and it has exceeded my expectations. Although I installed it in reverse, sucking the air out and blowing it into the open air, it has effectively eliminated the musty smell that was present in the crawl space. Living in a humid location, this fan has been a game-changer for me as the smell was even leaking into my vents and spreading throughout my home. I am extremely satisfied with the results.

Furthermore, I have also utilized this fan to keep my basement dry during heavy rains in the US north-east. I placed it in a basement window using a piece of plywood, allowing me to draw air in or out as needed. While it is a bit loud, I simply turn it off when I'm in the basement doing laundry. Overall, it functions exceptionally well and has proven to be effective in keeping my basement dry.

During the remodeling of my home, I expressed my desire to install fans in the crawl space to my wife. To my surprise, she found this particular fan that perfectly met my requirements. I have always believed in taking care of the crawl space to prevent any rot issues, and this fan has played a crucial role in ensuring fresh air circulation. Installing it was a breeze, and it has lived up to its heavy-duty reputation. I am so impressed with its performance that I plan on purchasing another one to achieve cross circulation of air. The price point is unbeatable, and I am grateful that my wife found this gem.

In my garage, where there are no windows and insulation is lacking, heat relief has been a challenge. However, this fan has come to the rescue. I mounted it on the outer wall and ran a new Romex line with a plug-in box to ensure easy access for turning it on and off. The fan is incredibly powerful and effectively moves a significant amount of air out of the garage. While insulation is on my to-do list, this fan has proven to be a reliable solution in the meantime. Its durability and humidity control feature make it a great commercial-grade exhaust fan.

The exhaust fan under review is a versatile and efficient solution for improving air circulation in various spaces.
