Ultimate Guide to Waterproof Fans: Choosing IP55 vs IP68 Waterproof DC Fans
Prevent costly downtime in outdoor telecom cabinets and energy storage systems by choosing high-performance industrial waterproof fans with the right protection level.
1. Why Standard Fans Fail
Moisture and salt spray lead to short circuits and bearing seizure. TKFAN's heavy-duty waterproof fan series solves these issues through Full Vacuum Potting.
2. IP Rating Comparison

3. IP Waterproof Rating Chart (IEC 60529 Standard)
| IP Level | Protection Level | Test Conditions & Duration |
|---|---|---|
| IPX4 | Splashing water | Water splashing against the enclosure from any direction. (10 min) |
| IPX5 | Water jets | Water projected by a nozzle (6.3 mm) against enclosure. (3 min) |
| IPX6 | Powerful water jets | Water projected in powerful jets (12.5 mm nozzle). (3 min) |
| IPX7 | Temporary immersion | Immersion in water up to 1 meter depth. (30 min) |
| IPX8 | Continuous immersion | Suitable for continuous submersion specified by manufacturer. |
| IPX9K | High-pressure steam | Protected against high-pressure (80–100 bar) water jets. |
* While IPX8 standards vary, TKFAN’s IP68 waterproof cooling fans are tested to withstand 3 meters depth for 72+ hours of continuous powered operation.
4. Advanced Waterproof Structures & Technologies
To satisfy diverse industrial needs, TKFAN utilizes two core manufacturing processes to deliver custom waterproof fan solutions. Whether you require cost-effective splash protection or a reliable, fully submersible industrial waterproof fan, our engineering ensures peak thermal performance.
Technology 1: Parylene Conformal Coating (For IP55 Waterproof Fans)
For environments exposed to high humidity, dust, or light splashing, we apply an ultra-thin, pinhole-free Parylene coating directly onto the PCB assembly of our waterproof cooling fans using advanced gas-phase deposition.
- Space-Grade Material: Provides 360-degree, uniform coverage on complex electronic components with negligible weight and thickness.
- No Loss of Efficiency: Unlike heavy shielding, Parylene preserves the waterproof fan's original dimensions and dynamic balance.

Technology 2: Full Vacuum Potting & Encapsulation (For IP68 Waterproof Fans)
For extreme applications demanding constant, trouble-free operation underwater, we utilize our signature epoxy resin potting technology to manufacture our premium IP68 waterproof fans under a complete vacuum chamber.
- Total Isolation: The entire motor and stator assembly of the waterproof DC fan are completely sealed inside a solid, high-density resin block.
- Maximum Durability: Eliminates internal air bubbles, keeping water, moisture, and high-pressure oil completely isolated from active electrics.
