About This

Independent Temperature & Humidity Trigger Control: One fan responds to temperature changes while the other reacts to humidity levels. When either reading exceeds or drops beyond the set value + deviation, the corresponding fan starts automatically, maintaining stable air conditions
Dual-Fan High Efficiency Air Exchange: Powerful 220 CFM dual-fan output accelerates airflow circulation, rapidly exhausting humid air, radon, and odors. Helps maintain a dry, breathable environment in crawl spaces, basements, attics, garages, utility rooms, and storage areas
Four Trigger Modes + Timer Scheduling: Supports C/H control modes for both temperature and humidity triggers. C Mode = activates when readings are higher than set range. H Mode = activates when readings are lower than set range. Built-in timer allows delayed start or timed shut-off for either fan, ideal for timer daily circulation
Full 304 Stainless Steel Housing: Constructed with 304 stainless steel and rust-resistant powder coating — built to withstand moisture, condensation, and long-term exposure. Ideal for damp areas such as crawlspace foundations, hydroponic grow tents, storage rooms and utility spaces
Slim Size, Ready to Install & Plug-In Operation: Compact profile fits most vent openings and foundation walls. Comes with a power cord for quick plug-and-run use — no wiring complexity required. Perfect for long-term continuous ventilation in basements, crawl spaces, attics, and enclosed rooms.
Please follow the instructions in the manual to set both the temperature and humidity controls simultaneously to ensure that both fans operate normally
