CADPXS Crawlspace Ventilation Fan – 220 CFM with Humidistat, Dehumidistat & Freeze Protection

Overview

The CADPXS Crawlspace Ventilation Fan is a compact, dual‑fan system designed to promote airflow between your crawlspace and the outdoors. With a robust 220 CFM output and a slim 18 x 9 x 2 inch footprint, it quietly moves air through tight spaces, helping to balance humidity and refresh air in areas like crawl spaces, basements, attics, garages, hydroponics tents, and similar spots where airflow matters.

Built‑in humidity controls give you practical RH management. The humidistat covers a 20% to 80% range, while the dehumidistat targets moisture levels to reduce damp conditions and support consistent air quality. The unit also helps vent odors and gases associated with treated wood and other materials, aiding in preventing localization of fumes into living areas when feasible.

Temperature Guard and Safety

A freeze protection thermostat works in concert with the dehumidistat to prevent operation when outdoor temperatures dip below 35°F. This safety feature helps ensure the unit remains reliable across seasonal changes and protects the system during cold periods.

Simple Setup and Wide Application

Easy to operate, the vent fan uses a knob control panel for quick adjustments. Just plug it in and set the desired run time, then let it work. A 6.56 ft grounded power cord provides flexibility for placement in crawl spaces, basements, attics, garages, hydroponics tents, and other sheltered areas.
