Combat Contaminants - Dust and contaminants often accumulate in enclosed spaces. Our 7-blade high-airflow fan creates a powerful ventilation system that helps you get rid of bacteria, moisture, and unpleasant odors.

Reduce Humidity - Extreme humidity causes walls to peel and paint to deteriorate. It can also lead to mold growth, which is harder to remove. One of the main benefits of exhaust fans is that they can improve humidity with a built-in dehumidifier.

Protects Health - Proper ventilation significantly reduces indoor air pollution and provides fresh, clean air, which reduces the risk of headaches, allergies, asthma, and other respiratory health problems.

Quiet Operation - With a noise level of only 55 decibels, it doesn't cause any booming sounds. Whether it's installed in the bathroom, attic, or basement, its independent work will never interrupt your activities!

Particulate matter, carbon dioxide, humidity, and mold are the main causes of air pollution in the home, and with poor ventilation, they can easily penetrate deep into the lungs and cause cardiovascular disease. High humidity and low sunlight below ground are the preferred environments for these creepy crawlies. Your basement and crawl space can bring any dangerous airborne substance into your living space.

The Ventripro 720S ventilation fan is the ultimate solution for efficient air circulation in your home. This powerful fan features a 10-inch blade that generates a powerful 720 CFM of airflow to ventilate rooms up to 7,400 cu. ft.

Simple operation: simple shape, control panel with buttons, no complicated electronic interface. Easy to install and change location, and you can easily put it in the bathroom, attic, or garage.

Energy-saving: memory function, when the humidity is higher than the set value, the fan will automatically turn on. When the humidity is lower than the set value, the fan will turn off. So you don't have to worry about it running all the time in the basement and consuming electricity.


Proper Use and Maintenance
INSTALLATION MATTERS: Crawlspace fans must be installed in electrical control boxes and motors facing inside the crawlspace.
1. Confirm that the doors and vent covers of the buildings around the installation are open.

2. In order to ensure the stable installation of the crawling space ventilator, it is necessary to mark four points on the wall to confirm the installation position.

3. Install the crawl space ventilation fan to the wall with 4 screws and observe the horizontal direction of the fan.

4. Note: If the mounting surface is a base block or brick. Before the fan is installed, a 5/16-inch hole needs to be drilled with a masonry drill bit. Install wall anchors at the openings and secure them.

If installed on a mesh of wood aggregate, edge joists, or existing crawlspace vents, secure crawl space vents with screws, washers, and nuts at the four corners of the metal panel of the vent.

I installed this on the inside of my crawl space so it works in reverse of how it is intended. I am sucking the air out and blowing through the vent into the open air. I live in a very humid location and the crawl has a musty smell, but ever since installing these fans there is no smell. So happy about it because the smell was leaking into my vents and blowing into my home.
Great product.

Actually using this to help keep our basement dry, which has been flooding from all the recent rains in the US north-east. Set it in a basement window, in a piece of plywood, so that I can draw air in or out, as needed. It is a bit loud, so I turn it off when I am down there doing laundry or whatever- but it works really well.

Great fan. It fit in a space I needed to vent air in. I got it installed with no effort at all. It blows well and the sensor triggers automatically so I do not just have to let it run all the time. Very good pricing since another model I was looking at before this was almost double the price!
Great value & quality

Our house is on a crawl space and we have had a lot of rain so we needed something (a fan) to help get it dried out and to hopefully keep it that way. This was super easy to install, put it on the vent, plug it in and WALLAW it was done. Much easier than so many others that we have looked at. So far it has been good. It seems like it is made very well and of great material as it is pretty heavy and the fan blades were not bendable. We could hear it but the noise was not overly loud so that was good because as long as we could hear it we knew that it was working pretty much. We have got two more vents on other sides of the house and decided to get fans for them as well to try and get the job done as quick as we could so we bought another fan (of another brand) and it was not as good and was much louder. So I think that we will stick with this one. Highly recommend this brand and seller due to the fact that this one came really quickly. It was packaged very well and you could tell that this seller really cares about their product and their customers.
Works well

This product was boxed well with protective foam on both sides. Fan comes with a cord so there is no need for any wiring. Fan can be set to auto and adjusted by control knob humidity settings. It will turn on when the humidity reaches the set point on control knob, or you can set fan to on and it will run continuously. Fan is pretty powerful, not to loud and runs real smooth. Looks to be built well. The instruction booklet was easy to read and understand.
Wow, just perfect

So as we have been remodeling our home i told my wife I wanted to install some fans in our crawlspace. Imagine my surprise when she got this and asked " Like this?" Heck yeah exactly what I wanted. It has always been just insane to me that people spend hundred of thousands on a home but neglect the crawlspace. I want to ensure I have zero rot from my crawlspace. After putting in a vapor barrier I installed this fan. It was so easy to install. It is definitely circulating bad air out from my crawlspace. It is keeping the air in the crawlspace fresh. This is heavy duty and comes with all the bells and whistles you need. I am getting another one because I want cross circulation of air. The price is unbeatable. I am very glad my wife got this.
Great exhaust fan- easy to mount and powerful.

My garage is not insulated and there are no windows, so the only heat relief is to hope the whirly bird vent up top takes the heat out- or open the main roll up door. I mounted this fan up on the outer- wood wall and ran a new Romex line with a plug-in box- to a location within 6 ft of this fan- and plugged into it. Down below- I have a switch wired into this extra power line so it can be turned off/ on without climbing a ladder. Seems to be very powerful and moves a lot of air out. I know that insulation would help a lot- but that is in the future- so for now this excellent fan system is going to have to do. This fan is very well-made, and the humidity control makes the fan somewhat automatic. Great commercial grade exhaust fan!
