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.
Exhaust: Don't let unpleasant odors and pollutants flood your home! With the new VentirPro ventilation fan, 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's perfect for keeping any home cool, dry and comfortable. Its built-in dehumidifier works non-stop to ventilate and dry up to 3,600 cubic feet and provides a maximum airflow of 260 cubic meters per minute.

Quiet: At only 40 dBA, this unit operates silently and won't disturb your relaxation time. Whether you're in the attic or the bathroom, you can enjoy the fresh air without worrying about being disturbed by noisy household appliances.

I ordered this fan to place in my greenhouse because it gets very hot and very humid very fast. It was easy to install and seems to be doing its job very nicely. I like the programmable thermostat and just needs set up and it does its thing on its own! It is smaller than I expected, but if helps with the heat and humidity, the $50 price tag is well worth it and I may order another one.
Great price. Great product. Prompt shipping. Pleasure doing business.

A Fan That Pulls Out The Hot Air

From the Amazon

By 'Pall C', Reviewed on April 12, 2023
This definitely blows the air...from one space to somewhere else when the humidity reaches a certain level. The adjustable thermostat is measured in percent of humidity. The temperature control is an automatic feature controlled internally, according to the product description. When this fan runs, it is kind of loud for its size. Kind of sounds like an old window AC. I suppose it would seem quieter if you were way across a room from it. It is not very large, so it could take a while to move enough hot air to feel the difference. The motor and fan seem powerful for its size. This would be well suited for an attic or storage building, shop space, or just about anywhere a space could benefit from venting the air. This unit performs well when needing to pull air out from a limited area. It brings value to a space with its air flow outward. Satisfied with this fan and the air ventilation it provides.
A Versatile, All-In-One, Temperature Activated Exhaust Fan Well Worth Considering.

From the Amazon

By 'M. Tucker', Reviewed on April 05, 2023
This arrived well boxed & protected, and when you open it up the controls are easy to understand and its mounting frame is also easy to figure out. We plugged this in and tested it, and other thermometers in the house were within a degree or two of what this unit would be set on in order to activate it. It is basically plug & play, you just need an outlet fairly close or otherwise be able to run a dedicated cord with an outlet to it. We tested it, but will install later when we will combine several "attic projects" into a one day event. This pushes enough air to make a difference in a small attic or otherwise in a crawlspace. We have cathedral ceilings that take away half our attic, but in the remaining space, which happens to be over bedrooms & bathrooms.I expect this to help cool the attic some when the sun is really bearing down. For a list price of $65.98 when I ordered, with a 5 % off coupon ($3.2995) for a final list price of $62.6905, considering this is very well constructed, control triggers are versatile, & a quick scan looking at other similar exhaust fans, all the facts together seems to point that this is a very good value at $62.69.
Quality Ventilator Fan

From the Amazon

By 'Puck', Reviewed on March 29, 2023
I recently received this crawl space ventilator fan and I am quite impressed with its performance so far. The fan is very quiet and powerful, with a CFM rating of 260. It also comes with a humidistat and thermostat, which helps to regulate the humidity and temperature in the crawl space. The installation process was fairly easy, and the isolation mesh was a nice added feature for keeping unwanted pests out. The fan is also rated IP-55, which means that it is protected against dust and water spray, making it suitable for use in potentially damp areas like a crawlspace or garage. One thing to note is that the fan does require a power source, so make sure you have access to an electrical outlet before purchasing. Overall, I think this fan is a good investment for anyone looking to improve their indoor air quality and regulate humidity in their crawl space, garage, or attic.
Glad we bought it

We have two a/c system, one is in the attic. It gets pretty warm up there. We originally got this to use I am our crawl space or even in our garage, but we eventually decided to use it up in the attic. Hubby said it is fairly easy to install. Not too loud. Hopefully, this will help during hot summer days. We might get another one for our garage.
solidly built...

This was installed as an attic space exhaust fan. We have a detached two car garage, uninsulated, that gets pretty hot during the warmer months. In this scenario, the humidistat function is not primary, as we are using it primarily for airflow to clear the heated air. It moves air well, with an appropriate noise level for the volume of air. Since it is installed in a space not typically inhabited, we installed it with a switch so we can operate it when needed. Works very well, and is very solidly built.
Pretty good vent fan

From the Amazon

By 'J-Zilla', Reviewed on March 21, 2023
I needed the fan for my small storage shed, it had a regular vent window but it was not cutting because it is very humid inside. The high humidity was causing cardboard boxes to get mold. The fan fit the existing vent cutout so installing was very easy, the fan includes mounting screws. For power I used a smart outdoor switch with extension chord. The smart switch protects the cable s power side and provides me with a programmable on schedule. The fan is humidity controlled so it will vent until the humidity level is reached. The build of the fan is pretty good and it also has an IPX rating. Overall I like the vent, it seems to be helping with my humidity issue.
This thing blows, or sucks, or both

(NOTE that checking out the reviews there are different sizes and models mixed together. Mine does not have a timer, but I see complaints about setting a timer) I am replacing the broken unit that is never worked in my house with the ALORAIR 260CFM Crawl Space Ventilator Fan, 6.7 Inch Basement Vent Fan with Humidistat & Thermostat. Initial impression is this thing is stout - and that is good. Everything about it appears to be made well, within tight tolerances, the metal is thicker than expected, the plastics are thicker than expected, the humidistat dial turns smooth, all edges are smooth and will not cut you, really there is nothing to dislike. After installing I have checked it a few times and played with the humidistat. I have found it running, as it should, several times as well. It is not a quiet fan but not inappropriately loud either. One thing I thought was a little funny is the manual says you can trim the faceplate as needed but no longer than a certain size. I do not have calipers to check thickness, but I certainly do not have any tools that will cut metal like that.
Helps remove humidity and heat from my shed

I like that this 6.7" ALORAIR 260CFM Crawl Space Ventilator Fan is pretty lightweight. It has a 6 foot cord, so it does not need to be direct wired. The instructions are hard to understand, but trial and error wins for this old senior. I just needed a fan that can pull the hot air from my shed and help with high humidity. This is just the right size for my shed.
