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
