AlorAir VentirPro 540S Ventilation Fan

Application

Airborne vapors and excess moisture not only promote mold and pests but can also attack and damage walls and furniture. Ventilation fans let fresh air in by extracting air from basements and crawlspaces. The built-in dehumidifier helps remove humidity from the environment. With the VentirPro 540S exhaust fan, with its 8.7-inch, 5-blade design, steam is quickly expelled outside and its operation at only 55 decibels won’t bother you. This makes it ideal for home use. With its powerful features and low power consumption, this fan is guaranteed to keep you quiet and comfortable.

Improved Air Circulation – The 540CFM axial fan reduces the risk of mold and vapor buildup by improving airflow and eliminating stagnant air. It circulates indoor air and brings in fresh air from outside. This improves air quality and allows you to breathe easier.

Reduce Indoor Humidity –  Ventilation fans are also very effective at reducing indoor humidity, especially when installed in bathrooms and crawl spaces. Stagnant and humid air is exhausted by dehumidifiers to prevent moisture buildup and create a healthy, comfortable indoor environment.

Cost Savings – ventilation fans are much cheaper than any dehumidifier or air conditioner, but they’re sufficient for normal dehumidification of crawl spaces and basements. And the memory function of our sensors automatically turns off when the humidity reaches the set level, so you save on electricity costs.

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.
