Keep indoor air clean - High-flow powered ventilator fan can quickly increase air circulation, expel radon gas, treated wood gases and indoor odors and prevent them from entering the living space. Creates a fresh living environment for you.

Reduces humidity - Extreme humidity means siding will peel and be damaged more easily. It can also cause mold and mildew to build up and become more difficult to remove. One of the most significant benefits of ventilator fans is that they reduce humidity, and figure it has adjustable humidity so you can set the perfect humidity level for your bathroom, attic, and work area.

Reduces airborne contaminants - 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 sort of mold problem, the blades can also remove any spores that have built up in the air. Slow down the growth of mold and mildew.

Protect the property - Many people store their possessions in the attic, but this part of the home can get hot and humid. When you use a ventilation fan to protect your objects, you don't have to waste the energy of an air conditioner to cool a vacant space. Attic ventilation fans can also protect insulation so you can worry less about cold air seeping inside in the winter.

Humidity can collect in confined spaces or in environments that lack outside air circulation. Prolonged moisture can cause wood to grow and rot, and damp wood can cause even more serious damage by attracting nasty groups like reptiles to chew on and eat away at it. What's more, airborne spores can enter your living space through floors and cracks and even crawl space HVAC, leading to indoor air pollution that endangers the health of you and your family.
The VentirPro 260 features a 6.7-inch wing fan with 260CFM air flow rate, a single fan for home use, and a panel that can be trimmed to match non-standard base openings so you can place it wherever you want to use it. With its features and great prices, you're sure to get the best results.

This unit is compact in size, 13" x 9" yet has a very powerful fan. One needs a 3-prong outlet near where it will be installed. This type of fan is only to pull the air from inside to outside. It also draws out humidity as long as it is the only opening (close all other basement windows). It has a manual knob so you can decide the setting. It will automatically turn off when the temperature outside drops, this was always when I would unplug it for the winter and place a board over it. You may need more than one depending on the size of the area.
Moves a good amount of air

I am actually using this to ventilate me shed. My vents are well positioned but were not getting enough air flow for cross ventilation. I have added this vent fan and it does a great job of moving the air through. The fan has a thermostat you can adjust so it is on at a certain temperature. It works well, it has a bit of noise but generally will not be someplace that will effect anyone. You do need an outlet within like 3 feet of the install.
Lot of power for a small fan - runs pretty quiet

From the Amazon

By 'Samuel W', Reviewed on March 10, 2023
I put this under my house to help the ventilation. This fan runs quiet for the power that it generates. The 260 was a little smaller than my vent opening but I just closed up one side with some tar paper and then used metal tape to make it air tight so it would pull from under the house. The humidity switch is pretty sensitive and shuts off when it hit the right humidity. You do have to tighten the screw on the end to get it to hold onto the post on the fan itself. If I had it to do over I might have sized up just so it would have fit better but the amount of CFM this moves is sufficient for my house. It did not take long to install it and probably took longer running a new outlet. I would recommend not putting this on a light circuit that has newer LEDs because they will slightly blink when this comes on. Works fine still though.
Sturdy and Well Conceived

Quiet and Powerful

I got this ventilation fan for a storm shelter I am building in my basement. I have not installed it yet but have been able to test it out uninstalled. This was easy as it uses a standard 110V outlet plug. Two main things I like about it is quietness and the power. First it moves quite a bit of air, making it great for a storm shelter like mine a larger crawl space. Second, the motor is pretty quiet, even at full speed. For comparison, this fan at max speed sounds similar to a standard box fan on low. Personally, I feel that it is a very nice product and I look forward to getting it permanently installed.
