Advwin Solar-Powered Exhaust Ventilation Fan Kit

Upgrade your poultry housing ventilation with Advwin Solar Exhaust Fan System! This dual-fan kit is perfectly designed for chicken coops, greenhouses, sheds, barns and small enclosed spaces, supporting free combination of air exhaust & fresh air intake to keep the internal environment cool, dry and breathable all year round.

Features:

• All-Day Power: 25W high-efficiency solar panel charges 30% faster than standard 15–20W models—fully charged in about 4 hours of sunlight. Built-in 2500mAh battery supports 5–8 hours of night use and slow-charges even on cloudy days to prevent downtime.
• 3 Smart Modes: High/Low for hot days, Timer mode (1h on / 1h off or 1h on / 2h off) for mild weather, and Auto-Sense mode with infrared detection. Set once and forget—cooling made simple. Controller Memory Function: Retains your last settings and resumes automatically after restart—no repeated setup needed.
• Infrared Auto Start/Stop – Auto-Sense Smart Mode: In Sensor Mode, the fan runs for 10 minutes when an animal is detected, then stops automatically to save energy. If animals are detected again, it restarts. Turn off Sensor Mode for continuous operation. Perfect for chicken coops or pet houses—add more units for larger spaces.
• Exhaust and Intake Mounting Way: Includes two powerful fans, 3 m fan-to-controller cable, and 3 m controller-to-panel cable—longer than standard cords for flexible setup. Mount both fans on one side for instant cooling or cross-vent for better air circulation and odor control.
• Durable & Weather-resistant Build: Durable ABS + metal housing resists rain and sun. Protective fan guards keep poultry safe. Works anywhere off-grid—chicken coops, sheds, RVs, tents, or greenhouses. The included full mounting accessories let you finish installation on walls, roofs or wooden panels quickly.
