As a company, we are strengthening the measures we have in place to protect the health of our employees.

What is "LEOS"? (Little bit Engineering of SDG)

Based on the SDGs (Sustainable Development Goals), we would like to contribute to the improvement of the working environment of our customers, such as the emission of harmful substances and the collection of dust, in order to achieve Goal 3 "GOOD HEALTH AND WELL-BEING".

We work out solutions for your spot of trouble, by combining our products (such as blowers and Mistresa models) with the various pieces of surrounding equipment. "LEOS" represents what we do as a company. The people coming up with flexible solutions in response to the issues our customers face are our team of experts who hold licenses stipulated in ordinances such as the Prevention of Organic Solvent Poisoning, the Prevention of Hazards due to Specified Chemical Substances, and the Prevention of Hazards Due to Dust. In addition to suggesting solutions, we also respond rapidly to requests for repairs and maintenance of machines. Please don’t hesitate to consult us, no matter what your spot of trouble involves— we will use our engineering skills to create safe, comfortable work spaces.

We will propose the optimum environment improvement according to the use!

    Evaluating Respirators with Fit Testing Fit Testing Service
    SDG conducts quantitative fit testing, an evaluation method that has been adopted worldwide.
    What is fit testing?
    Fit testing is used to determine the suitability of the welding respirators typically worn by workers.
    This service uses a dedicated measuring device to determine whether a particular respirator fits a worker’s face perfectly.
    On April 1, 2023, fit testing becomes a legally required procedure.
