Maintenance of soundproof room
From Japan

I was looking for a mismatch of the one I used before for the soundproof room and it reached this. However, the noise was bigger than the one I used before, so I did not use it after all. Looking at the specifications, there was not much difference in noise, but it was surprisingly big when used, and it was not useful for speech recording. Although it may not be a problem in the factory etc., since it is used indoors, next time I will buy a fan with super quietness.
Small room ventilation

Noise like bearings grounder is big 2 points. Because it is used like a small ventilation fan, I can stand it, but it is noise that many people feel unhappy in case of using purpose such as cooling equipment.

Cooling effect is sufficient with sufficient air volume, operation noise is not bothersome. It is satisfactory enough.
Replacement with the AC fan that was attached to purchase equipment
From Japan

More than 10 years ago, I replaced the AC fan that was attached to the equipment I had purchased because it was out of noise (noise). Since the mounting screw hole was small, it was replaceable without any problem except it spread to 4 mm. (It was not that much load to spread the screw hole.) Since the same AC fan is attached to the same equipment, we are considering replacing it at this time.

Used for waste heat of detector cabinet

By exchanging the fans that were originally attached, there was exactly the same thing so I ordered it immediately. Mounting holes pass 3 mm screws, but 4 mm screws do not pass. The fan which was originally attached was slightly struggled because 4 milliseconds was used. I was lost as to whether to tap a hole or fix with a tapping screw, but in the end I chose to drill a hole with a 4 mm drill. Since the frame itself was aluminum, the processing itself was easily expandable with ordinary iron drills. There is no problem with the silence and power of the fan, and it works smoothly. I think it is a very good product.
Small greenhouse, changing fan for improvement
From Japan

Since detailed data was verified on the net before purchase, satisfactory fans could be purchased. In the store I got acquainted last year, wind noise is large because of few products, so I replaced it this time. Thanks to that, I finished it as a convincing one. The price was also cheap, the fans reached quickly and above all, and it was able to improve in a short period of time.
