5. Setup and Installation
The REPTI ZOO PFS01 fan offers multiple installation options to suit various terrarium types.
5.1 Magnetic Mounting
For terrariums with a metal mesh top, the fan can be easily mounted using its strong magnetic base. Simply place the main fan unit on top of the mesh and secure it with the magnetic bottom lid from underneath. No tools are required for this method.

This image shows the fan unit securely attached to the metal mesh lid of a terrarium, demonstrating the magnetic mounting feature.
5.2 Glass Mounting (using suction cups)
For glass terrariums, the fan can be fixed to the glass using the provided suction cups. Attach the suction cups to the designated points on the fan unit and then press firmly against a clean, dry glass surface inside the terrarium.
5.3 Cable Pass-Through Installation
Some terrariums feature dedicated cable pass-through holes. The fan can be installed by fitting it into these holes, ensuring a snug and secure fit.
This video demonstrates three installation options: using a base support, fixing to glass with suction cups, and installing on a cable pass-through hole. It also shows the fan's effect on air quality and how to set up the device's timing functions.
5.4 Connecting the External Sensor
The external sensor plugs into the 'SENSOR INPUT' port on the fan unit. This allows for more accurate environmental sensing within the terrarium.
This video illustrates the use of the external sensor for precise environmental monitoring and shows how the fan operates based on humidity settings.
6. Operating Instructions
6.1 Setting Humidity Threshold
- Long press the "SET" button to enter the humidity setting mode.
- Short press the "SET" button to adjust the desired humidity value.
- Wait a few seconds for the setting to save and the fan to start if the current humidity exceeds the set threshold.
This video demonstrates how to set the humidity threshold and shows the fan activating when the humidity level in the terrarium exceeds the set value, and turning off when it drops below.
6.2 Manual Fan Operation
To manually start or stop the fan:
- Short press the "SET" button to manually start the fan.
- Short press the "SET" button again to manually stop the fan.
6.3 Adjusting Wind Speed
The fan features a gear adjustment for wind speed. Slide the gear to the left for a larger wind volume and to the right for a smaller wind volume, according to your terrarium's needs.
6.4 High Temperature Alarm
If the room temperature exceeds 100 degrees Fahrenheit, the device will display "HH" as an alarm. This indicates an excessively high temperature environment.
This video provides a comprehensive look at the fan's operational features, including how to set the humidity, adjust wind speed, and the high temperature alarm function.
6.5 Expanding Ventilation with Multiple Fans
The main fan unit includes a deputy fan connection interface, allowing you to connect an additional fan to strengthen the ventilation effect and further enhance air circulation within larger terrariums.
This video shows the effectiveness of using two fans for enhanced ventilation and humidity control in a terrarium, highlighting the expansion capability.
7. Maintenance
7.1 Filter Replacement
The filter element can be replaced easily. Regularly check the filter for dust and debris and replace it as needed to maintain optimal air purification performance.
This video illustrates the simple process of replacing the filter element and reiterates the fan's key features for terrarium air purification.
8. Troubleshooting
- Fan not turning on: Check if the power adapter is securely connected and if the humidity threshold is set correctly. Ensure the external sensor is properly plugged in.
- Fan running continuously: Verify the humidity threshold setting. If the ambient humidity consistently exceeds the set value, the fan will continue to run.
- "HH" displayed: This indicates a high temperature alarm. Check the room temperature and ensure the terrarium is not overheating.
- Reduced airflow: Check the fan's wind speed adjustment. Clean or replace the filter element if it is clogged with dust.
