Cleaning the coolant tank that used to take a whole day is now done in just 10 minutes! Improving cleaning efficiency and reducing unpleasant odors contribute to environmental improvement!

The automobile manufacturer Company I had three people working almost a full day to clean the coolant tanks of machine tools, and this had become the norm (standard operation). Therefore, we introduced the 'APDQO-F'. It allows one person to perform the task, and the working time was remarkably improved to about 10 minutes. Additionally, for machine tools that were difficult to manage, we had been outsourcing the work, which incurred costs. However, after the introduction, we were able to perform the work in-house, leading to cost reductions. [Solution] ■ APDQO-FF Non-woven fabric filter type for drum cans - Replaceable non-woven fabric, disposable type ■ APDQO-FS SUS filter type for drum cans - The filter is made of stainless steel, allowing for repeated use *For more details, please refer to the PDF document or feel free to contact us.

Cutting fluids for machine tools can be reused! Tank cleaning time is drastically reduced!

**APDQO Series** APDQO-FF100 (Non-woven Fabric Filter) APDQO-FS100 (Stainless Steel Filter) APDQO-FB100 (Bag Filter) ◎ Does not use electricity ◎ Automatically stops when full ◎ Equipped with a safety valve as standard **Benefits** ● Enables reuse of cutting fluid ● Improves tool life ● Safe due to air drive with no electric leakage ● Cleaning time as short as 5 minutes **Features** ● Designed specifically for JIS standard 200L open drums ● Capable of separating cutting fluid and chips ● Safety valve and float included as standard **Applications** The air-operated tank cleaning filtration cleaner APDQO-F series is capable of cleaning tanks of machine tools, as well as filtering and separating 'liquids' and 'solids'. Therefore, in addition to filtering chips and sludge from machine tools, it can be used in the following ways: ● Cleaning machine tool tanks (removing chips and sludge and reusing cutting fluid) ● Separating and sorting food waste in food processing plants (restaurants) ● Separating water and sludge from mountains and rivers ● Separating and sorting waste and sewage

The recognition that "the PDF invoice received from the other party must be stored as electronic data" is widely accepted. However, is that response truly sufficient for perfection? ◆ The "receipt" of electronic transactions includes issuance and delivery The Electronic Bookkeeping Act defines "electronic transactions" as the receipt of electromagnetic records related to transaction information. Breaking down the term "receipt" is key to understanding. - "Receipt": Receiving electronic data such as invoices and receipts from business partners - "Issuance": Issuing and delivering electronic data such as invoices and estimates to business partners When downloading a PDF from your company's accounting system and attaching it to an email, or concluding electronic contracts through a cloud-based invoicing service, both the receiving party and the issuing party (your company) are obligated to store the data. 【Utilizing paperlogic DESKTOP for document management】 - Elimination of manual input - Assurance of reliable searchability - Centralized management of receipt and issuance → paperlogic DESKTOP addresses the challenges of complex metadata management in the storage of these issued documents.
