Anti-Vibration & Low-Noise Fan
For Waterproof Camera Housings
This cooling system for waterproof camera housings combines a heat sink with a low-vibration, ultra-quiet fan.
The internal fan promotes air circulation, efficiently transferring heat generated by the equipment to the heat sink. Heat is then dissipated to the outside while maintaining the housing’s sealed structure, helping to prevent internal temperature buildup and hot spots.
An O-ring-based floating mount minimizes the transmission of fan vibrations to the housing and camera. By combining low vibration, quiet operation, and efficient heat dissipation, this system helps maintain a stable operating environment for outdoor cameras and precision equipment.
Features
Sealed structure compatible
It adopts an O-ring sealing structure, making it suitable for waterproof housings and other enclosures requiring a high level of airtightness.
Floating vibration-isolation mount structure
To improve heat dissipation efficiency, forced convection of the internal air is essential.
This system promotes air circulation within a sealed environment by incorporating a vibration-isolated fan structure, which suppresses vibration and resonance noise and ensures stable cooling performance even inside airtight housings.
Ultra-quiet fan for 315
Equipped with an ultra-quiet fan with a noise level of approximately 9.8 dBA (A-weighted).
Even when evaluated based on human hearing perception, this is an extremely low value. It is comparable to the sound of breathing or rustling leaves, meaning that in a typical indoor environment, the noise is effectively masked by ambient sound.

Assembly Instructions
When assembling the vibration-resistant fan structure, please use a thread-locking adhesive (LOCTITE 243) on the all screws.
If a thread-locking adhesive is not used, the screws securing the fan may loosen due to vibration.
