③Examples

・Auto Roller (AR) …

A filter is installed on the air intake of machine tool control panels, compressors, and other equipment, and is automatically wound up.

Settings such as the length of each roll and the frequency of winding (e.g., every X days) can be configured using a dedicated app.

・Manual Roller (MR) …

Filters installed on machine tool control panels or compressors are wound up manually.

④Results

We asked customers who are in the process of implementing the system for their feedback!

Even in areas with a large number of machining centers where it’s difficult to use a stepladder, the Auto Roller makes it easy to perform regular replacements—it’s incredibly convenient!

Since the air intake is located high up, and changing the filter using a stepladder in an oily work environment can be dangerous, it’s a real lifesaver that it can be replaced automatically on a regular basis!

I’ve been so busy with work that I couldn’t find the time to change the filter, but it was so easy to do that it saved me a ton of time!


We can also handle large air conditioners using manual rollers!
