Dear Sir/Madam, I hope this message finds you in good health and spirits. We would like to inform you that starting from our shipments on April 22, 2024, we will be renewing the design and specifications of the "Stainless Steel (SUS) Open Pail (APPQO-SK)." This improvement aims to enhance usability as a product specifically designed for air vacuum cleaners, focusing on weight reduction and quality enhancement. The main change will be in the shape of the handle, while there will be no changes to the material, capabilities when combined with air vacuum cleaners, product name, or JAN code. Please note that there may be instances where old models are delivered from our distributors and retailers. In such cases, we will not be able to accept returns or exchanges, so we appreciate your understanding in advance. We apologize for any inconvenience this change may cause and sincerely ask for your understanding. We look forward to your continued support.

We have published a document titled "Protecting Health with Dust Control! vol.1," which explains health disorders caused by dust. Dust refers to the general term for solid particulate matter suspended in the atmosphere, including fumes generated during welding operations. Various work processes exist on-site, and the materials handled are diverse, resulting in the generation of several types of dust. These dust particles can enter the body through inhalation via the mouth or nose or through contact, leading to harmful health effects. The document introduces the substances that cause health disorders and representative workplaces where they occur. If you are interested, please download the PDF from the related catalog below or feel free to contact us.
