Stainless Steel Crawl Space Vent Fan with Humidistat Dehumidistat

The AlorAir underground ventilation system can easily address the issue of a perennially confined crawl space that lacks outside air circulation, causing moist air to collect in the space. Prolonged moisture leads to mold growth and wood rot, which can compromise the structural integrity. Additionally, airborne particulates can enter the living space through floors, cracks, and even crawl space HVAC systems, creating an unhealthy environment for you and your family.

The crawl space ventilation fan simply discharges the moist air from the confined space, allowing fresh air from the outside to enter, more effectively removing excess heat, moisture, dust, and odor in various spaces, whether it's a crawl space, basement, garage, or carpentry workshop.

The fan system features several key advantages: - Isolation mesh to prevent particulates from entering the machine and affecting normal operation, while also stopping particulates from crawling into your living space. - A stainless steel mounting frame with high water resistance and protection, allowing the fan to cope with various weather conditions. - A knob control panel with a dehumidistat, enabling easy humidity setting within a 10-80% RH control range, without a complicated electronic interface.

The fan's built-in features ensure optimal performance and longevity: - A built-in dehumidistat maintains the desired humidity level, and an antifreeze thermostat stops the exhaust fan when outside temperatures are too low, extending the machine's service life. - A memory function automatically starts the fan when humidity exceeds the set value, and stops it when humidity falls below the set value. - Canned ball bearing motors reduce energy consumption and noise levels. - The wall-mounted installation is suitable for a working humidity range of 10-80% and an operating temperature range of 35-158°F, with a noise level below 55 dB.

Proper installation is crucial for the crawl space ventilation fan's effective operation. It must be installed in electrical control boxes with the motor facing the crawl space. Key steps include: 1. Confirming that the doors and vent covers of the surrounding buildings are open. 2. Marking four points on the wall to determine the installation position. 3. Securing the fan to the wall with four screws, ensuring the horizontal direction is correct. 4. If the mounting surface is a base block or brick, drilling 5/16-inch holes and installing wall anchors before mounting the fan.

The AlorAir VentirPro series offers various fan models to suit different crawl space sizes, with airflow capacities ranging from 260 CFM to 720 CFM. All models are ETL-certified and come with a 2-year warranty, supported by a professional customer service team.
