Smart, self-contained ventilation for outdoor coops

The ecoCalm Solar Exhaust Fan blends clean solar power with practical control to create a healthier, more comfortable space for your poultry. With dual 5.5 inch fans and a compact, weather-ready design, it brings gentle airflow exactly where you need it.

Powered by a bifacial solar setup and a rechargeable battery, this unit can run for up to eight hours on a full charge when sunlight is ample. It automatically shifts between solar and stored power as conditions change, so ventilation remains available even on cloudy days or after sundown.

Smart power and back-up

  • The system uses a dual-source approach, balancing daytime solar power with stored battery energy for night use.
  • Automatic mode switching helps maintain airflow without manual intervention.
  • The built-in intelligent thermostat lets you tailor when the fans activate based on ambient temperature.

Outdoor-ready design

  • IP44 weatherproof blades and a weatherproof plug ensure durability in exposed spaces.
  • A long 11.8 inch to 43.4 inch cable gives flexible installation options, from windows to walls.
  • Easy mounting makes it suitable for chicken coops, greenhouses, sheds, garages, and more.

Airflow and efficiency

Two balanced 5.5 inch fans deliver a robust 169 CFM, designed for spaces up to 850 ft³. A 16W rear panel can capture light from both sides, boosting potential power generation and supporting battery charging when sun is available. The overall setup can improve ventilation efficiency under bright sun by leveraging dual-surface light capture.

Practical use cases

Picture a coop that stays cooler on hot days and maintains better air quality during seasonal changes. In a greenhouse, the same unit helps vent excess heat while staying ready to operate when light fades. The system is built for real-life scenarios, offering benefits as possibilities rather than guarantees.

What you get

  • Dual 5.5 inch fans for effective ventilation
  • 12–41W potential power generation from the bifacial panel under ideal conditions
  • Battery back-up for extended operation when sun is limited
