Website Renewal! Celebrating 122 Years, When it Comes to Dry Vacuum Pumps and Rotary Blowers, Think of Unosawa Ironworks.

Energy-saving and maintenance-free! Compact air-cooled dry vacuum pump for clean processes.

The "KTS type" is a lightweight and compact air-cooled dry vacuum pump. Due to its durable Roots design, it has a long maintenance cycle and can also exhaust water vapor. It is ideal for non-corrosive gas applications that require clean vacuum and high reliability without oil back-diffusion. 【Features】 ○ Clean vacuum ○ Air-cooled ○ Lightweight and compact ○ Strong against water vapor and mist ○ Low noise and low vibration For more details, please contact us or download the catalog.

• Vacuum pump

Multi-purpose series! Rotary blowers developed based on extensive experience and achievements.

The ARJ type is a rotary blower (Roots blower) that incorporates a three-lobe rotor and combines the technology of Unosawa Group Co., Ltd. to achieve high performance, low noise, and low vibration. This series is highly standardized and can be used widely from low pressure to high pressure and from low flow rates to high flow rates. It also accommodates special gases, low-temperature fluids, and high-temperature fluids. 【Features】 ○ High reliability ○ Support for special specifications ○ Selection of optimal shaft sealing structure ○ Support for special materials and surface treatments ○ High pressure resistance specifications available For more details, please contact us or download the catalog.

• Positive Displacement Pump

Extremely robust against condensate! Vertical dry vacuum pump for chemical processes.

The "TRV Series" is a versatile dry vacuum pump (Roots vacuum pump) uniquely developed as a vacuum pump that is strong against condensable gases. The gas flow path is arranged to flow from the top to the bottom in a Down-Flow manner, allowing mist and liquids condensed inside the pump, which are drawn in with the gas, to easily flow down to the discharge port and be expelled or collected under atmospheric pressure. Therefore, it is an extremely robust pump against the inflow of mist and condensate from gases. In addition to the standard FC material, corrosion-resistant materials are also available for selection. 【Features】 ○ Strong against liquids ○ Energy-saving and high-performance design ○ Low temperature rise ○ Capable of drawing high-temperature gases ○ Small installation footprint For more details, please contact us or download the catalog.

• Other pumps

Ideal for the suction of condensable gases! General-purpose dry vacuum pump for chemical processes.

The "TRM Series" is a general-purpose dry vacuum pump (Roots vacuum pump) with many years of experience and numerous achievements. It can operate efficiently and stably at a consistent temperature thanks to the intermediate cooler. Additionally, it is capable of recovering condensates such as solvents and is suitable for suctioning condensable gases in vacuum drying, distillation, and degassing processes. The dry vacuum pump can cover a wide exhaust speed range from approximately 2m³/min to 35m³/min, and it can also accommodate special specifications made of corrosion-resistant materials such as stainless steel. 【Features】 ○ Wide operating range ○ Completely dry ○ No water contamination ○ Long-term continuous operation For more details, please contact us or download the catalog.

• Vacuum pump

Wide variety of shaft seals are available!

The ARJ type is a rotary blower (Roots blower) that incorporates a three-lobe rotor and combines the technology of Unosawa-Gumi Iron Works, Ltd. to achieve high performance, low noise, and low vibration.

From July 15 (Tuesday) to July 20 (Sunday), 2025, the "42nd Daihatsu Japan Open 2025 Badminton Championships" was held at the Tokyo Metropolitan Gymnasium. We would like to report on the motion capture experience session conducted by Yonex Co., Ltd. at the venue. During the experience session, participants were asked to swing three different types of rackets from different generations, focusing on whether there were differences in their top speeds. The measurement was conducted using the same Raptor-12HS system utilized at the Yonex Performance Innovation Center (Blue Lab). This was a valuable opportunity to experience the research equipment that is not currently open to the public and to see what kind of measurements are being conducted! ---[Yonex Co., Ltd.

Hello, this is the public relations department of KAITAKU Co., Ltd. in Okayama City, Okayama Prefecture! Recently, our wooden lightweight hyper CLT sheet has been officially registered with the Ministry of Land, Infrastructure, Transport and Tourism (NETIS number: TH-250021-A). The decisive difference between hyper CLT sheets and conventional temporary materials lies in the "exit" after their durability period ends. The hyper CLT sheet (NETIS number: TH-250021-A) is not discarded after its role on site is finished; instead, it is reused as chip fuel for biomass power generation. • Made: It is made from **wood (thinned timber)**, resulting in low environmental impact. • Used: It significantly contributes to reducing CO2 on site. • Converted to energy: Once its durability period is over, it becomes chip fuel for biomass power generation, ensuring that no resources are wasted. In this way, a **"complete circular" system** is established that connects materials to energy. Additionally, these initiatives can serve as a strong appeal for creativity related to construction performance. Please try the hyper CLT sheet (NETIS number: TH-250021-A)!

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. Many implementation examples are also presented, so please take a look at the case study page.
