Control impurities – The air inside can be more polluted than the air outside. Our ventilation fan creates a powerful ventilation system that will help expel a build-up of pollutants, bacteria, moisture, and unpleasant odors.

Reduce humidity - Extreme humidity means walls can flake paint and get damaged. It also causes mold to build up and is harder to remove. One of the most significant advantages of exhaust fans is that they allow for less humidity.

Guard Health - Often, aggressive chemicals are used to clean spaces and these chemicals can cause health problems when inhaled. This can become a serious problem, especially for children and the elderly. If the bathroom is already facing some kind of mold problem, the blades can also remove any spores that have built up in the air. It also helps slow the growth of mold.

Protecting belongings - Many people store their belongings in the attic, but this area of the home can get very hot and humid. When you run an exhaust fan to protect your boxes, you don't have to waste the energy of an air conditioning unit to cool an unoccupied space. An attic exhaust fan also protects the insulation so that you can worry less about cold winter air seeping inside.

Mold can enter your home through open doors, windows, vents, and heating and air conditioning systems. Mold spores grow quickly when they land in areas of excessive moisture, such as roofs, pipes, walls and plant pots where leaks may have occurred. Many building materials provide the right nutrients to encourage mold growth. Exposure to damp and moldy environments can lead to a variety of health effects. Some people are sensitive to mold. For these people, exposure to mold may cause symptoms such as nasal congestion, wheezing, red or itchy eyes or skin.
The VentirPro 720 uses a 10-inch aerosoil fan that generates 720 CFM of airflow to provide more efficient ventilation and covers up to 7,400 cubic feet of space. The single fan can be trimmed to match non-standard foundation openings so you can place in basements, attics, garages and any space where air circulation is needed.

Exhaust: Don't let unpleasant odors and pollutants flood your home! With the VentirPro720 ventilator, you can safely and effectively remove all unpleasant odors from the air. This powerful fan is designed to remove air pollutants quickly, without any chemicals or complicated processes.

Dehumidification: It is perfect for keeping your room cool, dry and comfortable. Its built-in dehumidifier works non-stop with a maximum airflow of 720 cubic meters per minute and ventilates and dries up to 7,400 cubic feet.

Safety: This unit has a built-in thermostat that turns on a self-protection mechanism when it detects an outdoor temperature below 33°F/3°C, stopping the dehumidifier from operating and preventing fan failure.

I installed this fan in my crawl space, venting to the outside through one of the vent holes in the foundation wall. Living in NC the humidity is off the charts in summer and I started getting a moldy smell from the AC floor vents last summer when the humidity levels get high. This fan works hard, but has made a substantial difference to the buildup of condensation in the crawl space and cold ducts. So far no moldy smells. The build quality is good and the noise levels are not too high. I cannot tell if the fan is running when I am in the house. Installation was quite straightforward and I had a power point nearby to simply plug the fan in. Its been running without issue for several months now.

This is a well made and very useful fan for different applications, and it is so simple to install. It is a little noisy but being used outside this does not bother me. I am actually using mine as a exhaust vent in my chicken house. Does great when set on 50% humidity. I do recommend this fan.

Solves the issue in my attic

I got this to use in our attic. We have had some issues with moisture and humidity even after adding things to the eaves that were supposed to help. This fit easily into the opening in the attic. I like that it has a switch dehumidastat that can be set to what humidity you want. It also has a freeze protection thermostat that will shut down the fan when the temperature falls below 35. So far it is working fine. My husband had no issues installing it.

Easy to install and runs quietly. Being able to set humidity and temperature make all the difference in the world. The price is not bad considering how well this is made, it feels like it will last for many years. I would buy again.
Solid quality for humidity control, not so much for temp.

I used this fan in my attic to pull cooler air from the North side of the house. Because I live in a drier region of the country, the air in the attic will not be as humid, just hot. Even when I set the humidity setting at the lowest, I find that it will only turn on during the morning and evening when the humidity is up. So I had to install a temperature switch and turn the setting to "ON". I wish they had included a temperature control, but now this fan works great as I intended. It feels like 10 degrees cooler with this fan on.

I purchased this for a mobile mechanic trailer that i own. Having problems with condensation and rust on tools. I mounted this high on rear door and you can really feel the air moving! The freeze feature is a real bonus here in the northeast. Installation was very easy. Been testing this for a week so far tools have been dry. Being waterproof is perfect for my outdoor application. This is also draws very little power, which will allow me to use it when not hooked up to shore power thru my inverter.
One works great, one failed after 8 hours of use
