Precaution 1. The dry box only dehumidifies and cannot humidify. Therefore, when the ambient humidity is lower than the target humidity, the humidity displayed by the dry box will be basically consistent with the ambient humidity.

2. The dry box cannot control temperature, and it only monitors the actual temperature inside the cabinet, which fluctuates with the ambient temperature.

3. To achieve optimal dehumidification performance, ensure the glass door is tightly sealed against the cabinet body during operation.

4. Items must be fully dried before being placed inside the cabinet. Do not put damp items directly into the cabinet.

5. Humidity inside the cabinet will rise when the door is opened to put in or take out items. This is normal. It is caused by external air entering the cabinet or the humidity of the newly placed items being higher than the internal humidity. (The increase in internal humidity depends on the door opening duration, external air humidity and moisture contained in the items.)

6. The dehumidification speed is related to the ambient humidity and the dampness of stored items. Higher ambient humidity, more items or wetter items will require longer dehumidification time, and vice versa. If the target humidity range cannot be achieved after prolonged dehumidification, perform an empty cabinet test to verify the dehumidification function of the dry box.

Product Features 1. Heat-free effective dehumidification
It is designed for moisture-proof storage to preserve original filament performance.

2. Adjustable & accurate humidity control
The adjustable humidity range: 25-60%RH, matching storage requirements for different filaments and optical devices. The external digital display shows the real-time temperature and humidity. Data can be read without opening the cabinet door to prevent humidity disturbance inside the chamber.

3. Silence & low power consumption
The dry box runs at the low noise and power consumption, ensuring energy-saving and stable long-term operation.

4. Large capacity with flexible layout
The cold-rolled steel cabinet with a transparent tempered glass door allows direct visual check of the filament state. It is also compatible with camera lenses and precision electronic parts.

5. Secure locking & reliable sealing
The mechanical key lock prevents unintended opening and dust ingress, and protects valuable filaments and photography devices. The well-sealed cabinet body reduces external moisture intrusion.

6. Multi-purpose usage
One cabinet for multiple purposes: moisture-proof storage of 3D printing filaments, photography equipment, electronic components and collectibles.

　

Digital Display

The digital temperature and humidity display screen supports easy reading of temperature and humidity values. It is compact in size and sensitive in response, provides real time environmental monitoring.
　

　

Door

The transparent visible door allows clear observation of stored filaments without opening the cabinet. It is equipped with a key lock mechanism to secure the door for dust proof and moisture proof purposes.
　

　

Dehumidifier

The dehumidifier features multi-gear knob adjustment to set target humidity for different filaments with simple and intuitive operation. The modular integrated structure facilitates disassembly and maintenance.
　

　

Rear Panel

The rear ventilation and heat dissipation panel with the multi-groove structure accelerates heat dissipation of the dehumidifier module and prevents local heat accumulation inside cabinet. It is easy to assemble and disassemble.
　

Operation Method 　

A. Machine Placement:
1. Place the unit on a horizontal and solid surface. Maintain a clearance of no less than 5cm between the unit and surrounding objects or walls.
2. Do not place the unit in locations with drastic temperature fluctuations, direct sunlight, heavy dust, strong airflow, or dark and humid conditions. These environments will reduce or destabilize dehumidification performance.

B. Power On
Connect the power supply. The green operating indicator light on the core module will turn on, and the unit starts working.
Caution: Do not use an incorrect power supply. The unit is only compatible with the power adapter with the output of DC 5V and the current of 2A or higher.
Operation Sequence Note:
1. Insert the adapter plug into the AC power socket.
2. Then insert the DC plug of the adapter into the DC socket of the unit.

C. Humidity Setting & Adjustment
1. Select and adjust the humidity according to the stored items.
2. Turn the knob to the corresponding position, close the door, and run the unit empty for 8-12 hours. After the humidity stabilizes, check whether the reading on the hygrometer falls within the required humidity range.
3. If the humidity is located within the required range, open the door, place items into the dry box, and close the door.
4. If the humidity is located outside the required range, adjust the knob position:
(1) If the displayed humidity is higher than the required range, turn the knob slightly clockwise
(2) If the displayed humidity is lower than the required range, turn the knob slightly counterclockwise.
5. After fine adjustment, close the door and wait for internal humidity to stabilize, and then check the displayed humidity. If it is located within the required range, proceed to the Step 3. If it is located still outside the range, repeat the Step 4 until the target humidity is achieved.
