Fresh air circulation and odor control: This ventilation fan improves air exchange in reptile enclosures, helps remove odors, and provides a cooling breeze for your pet. Flexible mounting: Easy to install on the top grid or suspend inside the enclosure without tools. Compatible with a range of enclosure sizes and layouts, so you can position it for optimal airflow. Automatic humidity control: Automatically reduces enclosure humidity by 3-5% within minutes when the humidity reaches your preset threshold. No manual intervention required. Humidity levels are adjusted with an easy-to-use knob. Low-noise, high-performance design: Operates at a quiet 28 dB while delivering rapid air movement at 2700 RPM to expel hot air and keep the habitat cool and comfortable. Use scenarios: - Small to medium terrariums or vivariums where you need consistent air exchange and odor control. - Enclosures with misting or humidity cycles, where automatic humidity reduction helps maintain stable conditions without daily adjustment. - Enclosures with limited mounting options, where top-grid placement or suspension provides flexible, tool-free installation.
