The "Dry Vacuum Pump" is a high-efficiency vacuum system with an endless casing. Due to the integrated rotor and shaft design of the three-lobe Roots rotor, it operates with low noise and low vibration. Since it does not use internal lubricants, there is no backflow of oil to the high vacuum side, allowing for a clean vacuum. There is also no scattering of oil mist on the discharge side, protecting the working environment and the health of the operators. It can operate from atmospheric pressure and maintains stable performance over a wide pressure range. 【Features】 ■ Easy disassembly and internal inspection due to the split casing ■ Long-term continuous operation is possible without wear, making maintenance simple ■ Drain recovery of condensable gases is also possible ■ Simple structure with excellent durability ■ Shaft sealing uses a dry seal method For more details, please refer to the catalog or feel free to contact us. 【For inquiries, please contact our authorized dealer, HRD!】

The "FT6/CT6 series" is a roots-type dry vacuum pump. It is package-free and low-cost, making it ideal for replacing rotary pumps. The "CT6 series" is water-cooled, while the "FT6 series" is air-cooled. Additionally, we offer the "CT6-PC series," which is a packaged version of the "CT6 series," and the "MCT7 series," which combines with a mechanical booster. 【Features】 ■ 6-stage roots-type dry vacuum pump ■ Oil-free and dry gas contact parts for clean exhaust ■ High vacuum, high efficiency, and energy-saving ■ Eliminates performance differences due to power recycling ■ Package type can operate in various modes For more details, please refer to the catalog or feel free to contact us. 【For inquiries, please contact our authorized distributor, HRD!】

Here is a case study regarding a consultation we received about challenges in cleaning operations while proposing vacuum pumps in various manufacturing environments. The vacuum pump used by the customer was already equipped with a tar filter, but there was an issue where tar was bypassing the filter and entering the pump. We investigated the cause of why the tar could pass through the filter. We proposed a prototype that could meet the current conditions with slight customization of our existing product. After testing the prototype, the customer was able to successfully capture the vaporized tar, and they continue to work comfortably with it. 【Case Overview】 ■ Issue: Frequent failures due to tar passing through the filter and stopping the vacuum pump ■ Solution: Proposed the HS Collector, a vacuum pump protection device with many specifications ■ Result: Successfully liquefied and captured the vaporized tar *For more details, please download the PDF or feel free to contact us.
