We are receiving inquiries about our humidity control device for various applications. In response to the feedback, "It seems good, but I'm not sure if it really works," we are currently running a popular campaign for a 【free】 demo unit rental! The rental period is 1 to 2 weeks! Please experience the easy installation and operation by using it yourself. It is designed to be lightweight and compact, making it possible to share among multiple departments. Please take this opportunity to try it out!

The popular filter-equipped air blow gun, Unipo Air Gun, now has a new model made of PP in its lineup. Compared to the existing ABS model, it has improved chemical resistance!! Of course, the filter part maintains the same high filtration precision of 0.01μ!! Please give it a try.
